Layers and perimeters

<p dir="ltr">3D printers work by laying layer over layer of plastic to create a 3D object. Each new layer must be supported by the one beneath it. If part of your model starts in mid-air and is not supported by anything below, you need to add an additional support structure to ensure a successful print.</p>
<div class="tip-callout">It is worth considering altering the orientation of the model or splitting the model into multiple parts in order to possibly reduce overhangs and consequently the amount of supports generated.</div>
<p dir="ltr">PrusaSlicer can both detect areas that need supports and generate them in these places <strong>automatically</strong>.</p>
<p dir="ltr">You can also set supports manually using:</p>
<ul>
<li dir="ltr"><a href="http://help.prusa3d.com/article/paint-on-supports_168584">Paint on supports</a></li>
<li dir="ltr"><a href="http://help.prusa3d.com/article/modifier-meshes-custom-supports-and-other-magic_114258#custom-supports">Support enforcers and blockers</a></li>
</ul>
<p dir="ltr">Supports can be turned on from the <strong>right panel</strong> or in the <strong>Print settings - Support material - Generate support material</strong>.</p>
<p dir="ltr">There are 3 different Support styles in PrusaSlicer</p>
<ul>
<li dir="ltr">Grid</li>
<li dir="ltr">Snug</li>
<li dir="ltr"><a href="http://help.prusa3d.com/article/organic-supports_480131">Organic</a></li>
</ul>
<p dir="ltr">When the print finishes, depending on the model geometry and material used, the support structure is often easily removable with bare hands. You can use pliers to get a better grip in otherwise hard-to-reach places. A scalpel or a utility knife can also be used to cleanly remove a piece of support that seems to be stuck to the model.</p>
<div class="warning-callout">Pieces of supports can be surprisingly sharp and are sometimes violently ejected in a random direction after removal. When you encounter hard-to-remove supports, <strong>consider wearing protective glasses</strong> (this sounds stupid until you get hit in the eye for the first time).</div>
<h3 dir="ltr">Supports everywhere</h3>
<p dir="ltr">Supports can grow from both the print bed and any model surface when necessary. </p>
<p dir="ltr">This ensures that every overhang and part starting mid-air will get supported. However, small imperfections may appear on the surface where supports started growing from.</p>
<h3 dir="ltr">Supports from build plate only</h3>
<p>Creates only supports that have their base at the print bed.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only-300x171.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only-600x343.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only-768x439.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only-800x457.jpg 800w" alt="" /></p>
<p style="text-align: center;"><em>Supports from build plate only (left), supports everywhere (right)</em></p>
<h3 dir="ltr">For support enforcers only</h3>
<p dir="ltr">Automatic support generation is enabled only for areas marked with a support enforcer. This option is essentially a shortcut that turns <strong>Print settings - Support material - Generate support material</strong> on, but <strong>Print settings - Support material - Auto-generated supports</strong> off.</p>
<h3 dir="ltr">Supports on/off for individual models</h3>
<p dir="ltr">It’s possible to print multiple objects at once each with its own support settings. By default, all models are affected by the global settings. You can overwrite them by <strong>right-clicking</strong> on a model in the 3D view and selecting <strong>Support material</strong>. Alternatively, you can right-click on the editing icon in the Object list.</p>
<p dir="ltr">A new window will appear in the right panel called <strong>Object settings to modify - Support material</strong>. Changing these settings will affect only the relevant object and its instances. You can remove the settings overwrite by clicking on the red cross icon. When you do so, the global settings will once again be applied.</p>
<p dir="ltr"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-300x149.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-600x299.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-768x383.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-800x399.png 800w" alt="" width="495" height="247" loading="lazy" /></p>
<h3 dir="ltr">Support enforcer/blocker</h3>
<p dir="ltr">The automatic supports can sometimes appear in hard-to-reach places, resulting in a tedious removal of support structures. If you think such a part of the model could be printed without supports, but neither the <strong>Overhang threshold</strong> setting nor selecting <strong>Supports on built plate only</strong> helped, you can adjust supports manually.</p>
<div class="tip-callout">Starting with PrusaSlicer 2.3, you can also use <a href="http://help.prusa3d.com/article/paint-on-supports_168584">Paint on supports</a>.</div>
<p dir="ltr"><strong>Right-click</strong> on a model and choose either a <strong>Support blocker or Support enforcer</strong>.</p>
<p dir="ltr"><span style="color: #2dc26b;"><strong>Simple mode</strong></span> - Enforcers/blockers are always box-shaped</p>
<p dir="ltr"><span style="color: #f1c40f;"><strong>Advanced mode</strong></span> - Box/Cylinder/Sphere/Slab shapes</p>
<p dir="ltr"><span style="color: #ba372a;"><strong>Expert mode</strong></span> - Option to load external geometry as a blocker/enforcer</p>
<p dir="ltr">Support blockers and enforcers can be manipulated with the familiar Move, Rotate, and Scale tools. You can also quickly duplicate them with copy&amp;paste.</p>
<h3 dir="ltr">Support blocker</h3>
<p dir="ltr">Support blockers are useful when you’re generally happy with the automatic supports and you simply want to remove some of them. Focus on placing blockers where the supports meet the object, the rest of the support structure below will be removed automatically.</p>
<h3 dir="ltr">Support enforcers</h3>
<p dir="ltr">Support enforcers are great in situations, where only a few parts of the object need to be supported, but the automatic algorithm places supports all over the model. In this situation, don’t forget to switch the support mode to For support enforcers only. </p>
<p dir="ltr">It’s less common, but you can also use support enforcers with the automatic generation on.</p>
<p dir="ltr">Another interesting use of support enforcers is to split long bridges into smaller ones by placing a support in the middle of the bridge. You can repeat this process and print shorter, near-perfect bridges while still making the supports easy to remove.</p>
<div class="note-callout">Some options will only appear when <a href="http://help.prusa3d.com/article/simple-advanced-expert-modes_1765">Expert mode</a> is selected.</div>
<h3 dir="ltr"><strong>Generate support material</strong></h3>
<p dir="ltr">Supports are disabled unless a model has an overwrite for this setting</p>
<h3 dir="ltr"><strong>Auto-generated supports</strong></h3>
<p dir="ltr">When off, the overhang detection is off. Only support enforcers generate supports.</p>
<h3 dir="ltr"><strong>Overhang threshold</strong></h3>
<p dir="ltr">The Overhang threshold value represents the most horizontal slope (measured from the horizontal plane) that you can print without support material (90=vertical).</p>
<p dir="ltr">Changing this value is a quick way to adjust the amount of generated supports.</p>
<p dir="ltr">The lower the value, the less support will be generated.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold-300x171.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold-600x342.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold-768x437.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold-800x455.png 800w" alt="" /></p>

<h3 dir="ltr"><strong>Enforce support for the first</strong></h3>
<p dir="ltr">Generate support material for the specified number of layers counting from the bottom, regardless of whether normal support material is enabled or not and regardless of any angle threshold. This is useful for getting more adhesion of objects having a very thin or poor footprint on the build plate.</p>

<h3 dir="ltr"><strong>Raft layers</strong></h3>
<p dir="ltr">The object will be raised by this number of layers and support material will be generated under it. When the print finishes, you can grab the raft and peel it away from the part.</p>
<h3 dir="ltr">Raft contact Z distance</h3>
<p>The vertical distance between the raft and the object. Ignored for soluble interfaces.</p>
<h3>Raft expansion</h3>
<p>Expansion of the raft in the XY plane for better stability.</p>
<h3>Style</h3>
<p>Style and shape of supports. The default <strong>Grid</strong> supports have a very well-defined minimum area, making them very stable. However, they tend to leak out of regions they support along the walls of the object. The <strong>Snug</strong> supports maintain the shape of the overhang, so they do not leak to the walls. The trade-off is the possibility of lower stability of tall and thin support pillars.</p>

<p style="text-align: center;"><em>Grid supports (left), Snug supports (right)</em></p>
<p><a href="https://help.prusa3d.com/article/organic-supports_480131"><strong>Organic supports</strong></a> offer a completely different approach to supporting overhanging areas. Branches of support structures grow from the sides and automatically get denser beneath parts that need the support. The Organic supports are easily removable, do not scar the surface, and are fast and cheap to print.</p>
<figure class="image" style="text-align: center;"><img decoding="async" title="Support material" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/07/30cd916294dd7ac737ac7c09e1edfbb9.jpg" alt="" width="2011" height="1119" loading="lazy" /><figcaption>Grid supports (left), Organic supports (right)</figcaption></figure>
<h3 dir="ltr"><strong>Top contact Z distance</strong></h3>
<p dir="ltr">The vertical distance between the object and the support material interface.</p>
<p dir="ltr">Setting this to 0 will prevent PrusaSlicer from using bridge flow and speed for the first object layer.</p>
<p dir="ltr">Values between 50-75% of the layer height seem to work well.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-300x191.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-600x381.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-768x488.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-800x508.jpg 800w" alt="" /></p>
<h3 dir="ltr">Bottom contact Z distance</h3>
<p>Similar to Top contact Z distance, but affecting the gap at the bottom of the support tower (when supports start on top of a model and not on the build plate).</p>
<h3 dir="ltr"><strong>Pattern</strong></h3>
<p dir="ltr">Rectilinear - default, usually the easiest to remove</p>
<p dir="ltr">Rectilinear grid - sturdier and less prone to breaking during printing compared to rectilinear infill, harder to remove</p>
<p dir="ltr">Honeycomb - sturdy, somewhat difficult to remove</p>
<h3 dir="ltr"><strong>With sheath around the support</strong></h3>
<p dir="ltr">Creates a single perimeter around the supports, which makes them sturdier, but more difficult to remove.</p>
<h3 dir="ltr"><strong>Pattern spacing</strong></h3>
<p dir="ltr">Spacing between support material lines. Increase to make support removal easier. Support interface layers bridge over support material lines, if you increase this value too much, these bridges will start to sag and have an imperfect connection with the model.</p>
<p dir="ltr">The pattern spacing also sets the internal resolution of PrusaSlicer's supports grid. If you're using Paint-on supports or Support enforcers and you're unable to force supports exactly where you want them to be, try lowering the pattern spacing to get more resolution.</p>
<h3 dir="ltr"><strong>Pattern angle</strong></h3>
<p dir="ltr">Rotates infill pattern angle on the horizontal plane.</p>
<h3 dir="ltr">Closing radius</h3>
<p>For Snug supports only. Gaps smaller than the closing radius will be filled in.</p>
<h3 dir="ltr"><strong>Top interface layers</strong></h3>
<p dir="ltr">Interface layers form a more uniform surface between the object and the support material. These are preferably set to a much denser pattern than the non-interface layers so that you can both maximize the surface area of the support in contact with the model to prevent sagging while minimizing print time and material used with a bigger non-interface pattern spacing.</p>
<h3 dir="ltr">Bottom interface layers</h3>
<p>Similar as Top interface layers, but affecting the number of interface layers at the bottom of the support tower (when supports start on top of a model and not on the build plate).</p>
<h3 dir="ltr"><strong>Interface pattern spacing</strong></h3>
<p dir="ltr">Spacing between interface lines. Set to 0 to get a solid interface.</p>
<h3 dir="ltr"><strong>Interface loops</strong></h3>
<p dir="ltr">When enabled, the top layer of supports is covered with loops - continuous polylines.</p>
<h3 dir="ltr"><strong>Support on build plate only</strong></h3>
<p dir="ltr">Supports can start only on the print bed. Enabling this option is a really quick way to get rid of excess supports mostly on organic shapes. Make sure to check the preview and verify that all parts are either supported or at an overhang angle manageable by the printer.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only-300x178.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only-600x356.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only-768x455.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only-800x474.png 800w" alt="" /></p>
<p dir="ltr" style="text-align: center;"><em>Supports everywhere (left) vs Supports on build plate only (right)</em></p>
<h3 dir="ltr"><strong>XY separation between an object and its support</strong></h3>
<p dir="ltr">Sets the width of a gap between the model and supports. Bigger XY separation decreases the contact area of supports but makes them easier to remove and less prone to fusing to the model.</p>
<p dir="ltr">If expressed as a percentage (for example 150%) it will be calculated over the external perimeter width.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-300x151.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-600x301.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-768x386.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-800x402.jpg 800w" alt="" /></p>
<h3 dir="ltr"><strong>Don’t support bridges</strong></h3>
<p dir="ltr">Prevents support material from being generated under bridged areas.</p>
<h3 dir="ltr"><strong>Synchronize with object layers</strong></h3>
<p dir="ltr">Supports will be printed at equal layer heights as the model itself. This is useful with multi-material printers, where the extruder switch is expensive.</p>
<p>Synchronize with object layers can only be enabled with soluble supports (contact Z distance 0). </p>
<p>Not synchronizing with object layers allows the support layers to grow faster than the object layers (if not excessively slowed down by the cooling logic) and independent layer height also allows PrusaSlicer to follow the gap between the object and the support top surface precisely. We may consider this to be configurable even for non-soluble supports in the future.</p>

Customer support

<p>As there are ways of remotely transferring files and starting prints, an SD card or USB flash drive is the most common and reliable way to get your files to your machine. Though common and convenient, flash memory is not the most reliable in itself and your storage can be corrupted or fill up without any obvious signs. Therefore, we have put together a small guide on how to maintain, format, and purchase memory for your Original Prusa printer.</p>
<h3>Make sure your SD card is not locked!</h3>
<p>The SD card has a latch on the side. Before using your SD card, make sure that the latch is not set to the Locked position. In case it is locked, you will not be able to save files on the card, and the printer will not be able to open the SD card.</p>
<p><img decoding="async" style="max-height: 350px; display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-01.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-01-300x293.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-01-410x400.jpg 410w" data-hd-height="350px" data-hd-align="center"></p>
<h3>Storage over 32 GB</h3>
<p>There is no upper size limit on compatible storage media, but <strong>the built-in Windows formatting tool does not support formatting storage media from a size of 32 GB or more to FAT32.</strong> It will only provide the option for exFAT, which is currently not supported by our printers. There are similar limitations under various versions of Apple's OSx, where a third-party application must be used to format it correctly.</p>
<p>To format such a drive you need a third-party application, like Rufus, FAT32 format, or EaseUS Partition Master. <strong>Be careful when using such programs</strong> so you do not <strong>accidentally format the wrong storage media</strong>, like your hard drive. However, 8-16 GB is more than enough for most use cases, as a G-code file rarely exceeds 100 MB.</p>
<h3>How do I format the USB drive/SD card?</h3>
<p>If your SD card or USB drive is full or if you can't read the content of the drive, but the drive is recognized by windows, most often all you need to do is to format the drive.</p>
<div class="note-callout">If your USB drive or SD card does not even show up in your computer file explorer it is probably corrupted beyond repair, or at least beyond the scale of this article. If you get an error like the one in the picture below and it does not show up anywhere, off to google you go, but you might have to consider this card/USB drive lost and get a new one.</div>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-02V3.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-02V3-600x238.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-02V3-800x317.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-02V3-300x119.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-02V3-768x304.jpg 768w" alt="" width="631" height="250"></p>
<h3>How to format on Windows</h3>
<p>On Windows, this is very simple. Locate your USB drive or SD card in my computer, right-click, and choose format.</p>
<p><img decoding="async" style="max-height: 350px; display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-300x288.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-417x400.png 417w, https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-768x737.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-625x600.png 625w" data-hd-height="350px" data-hd-align="center"></p>
<p>A new small window will pop up. Most of the time you can simply leave everything to default, but the most important thing is that the <strong>File System is set to FAT32.</strong> This and the Volume Label (Name of the drive) is the only thing you want to touch here. Click Start and your drive will be formatted in a matter of seconds.</p>
<div class="warning-callout">Formatting any drive will delete all the content of the drive! Back up your stuff!</div>
<p><img decoding="async" style="max-height: 300px; display: block; margin-left: auto; margin-right: auto;" title="https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-04-166x300.png 166w, https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-04-222x400.png 222w" src="https://cdn.help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-04.png" data-hd-height="300px" data-hd-align="center"></p>
<div class="note-callout">If the USB stick will not work even after this procedure, it is either broken or its "partitioning scheme" is set as GPT, which is incorrect. <strong>It must be set as MBR (Master Boot Record).</strong> For how to change this, please see <a href="https://docs.microsoft.com/en-us/windows-server/storage/disk-management/change-a-gpt-disk-into-an-mbr-disk">Microsoft's official documentation</a>.</div>
<h3>How to format on Mac</h3>
<p>On Mac, it is a few more steps, but still very accessible. Again, you want to choose <strong>FAT32 as your file system</strong>, but you also have the option of changing the "partitioning scheme", which <strong>should always be MBR (Master Boot Record).</strong></p>

<h3>How do I get the kit or assembled printer owner discount?</h3>
<p>As stated on our website: <a href="https://www.prusa3d.com">Prusa3D</a>, if you purchase an assembled MK3S+ printer, we offer a 10% discount on your upcoming five subsequent purchases of an <strong>assembled printer of the same type</strong> and on 30 spools of selected filaments per year <strong>(not applicable to the</strong> <strong>MK4</strong>). If you choose to purchase your printer as a kit, we offer a 5% discount on 30 spools of selected filaments per year. In both cases, the discount is automatically activated in your account as soon as your first kit or printer is shipped.</p>
<h3>Can I have my printer signed by Jo?</h3>
<p>Yes, Josef can sign the machined aluminum card, which can then be attached to the printer in your preferred location, but please know it can delay the expedition for over a month. He is very busy these days. If it's OK with you, you can ask for the signature in an email or via Live Chat.<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2024/01/bab6f918412df530b7522cb2db60b3bf.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="FAQ - Frequently Asked Questions" alt="" width="421" height="255" loading="lazy" /></p>
<h3>What are the printer dimensions?</h3>
<p>The dimensions are (W×L×H or X×Y×Z):</p>
<ul>
<li>An assembled <strong>MK4/S, MK3.9</strong> printer measures 500×550×400 mm | 19.6×21.6×15.7 in, and 7 kg, without filament spool. </li>
<li>MK4 print volume: 250×210×220 mm | 9.84×8.2×8.6 in.</li>
</ul>
<p> </p>
<ul>
<li>An assembled <strong>MK3/S/+, MK3.5/S</strong> printer measures 500×550×400 mm | 19.6×21.6×15.7 in, and 7 kg, without filament spool.</li>
<li>MK3/S/+, MK3.5 print volume: 250×210×210 mm | 9.84×8.2×8.2 in.</li>
</ul>
<p> </p>
<ul>
<li>An assembled <strong>XL </strong>printer measures 580×700×900 mm | 22.83 ×27.56 × 35.43 in, and has a maximum weight of 25.3 kg. The width includes the Wi-Fi antenna and filament side sensor, and the height includes the cables to the extruder(s). </li>
<li>The assembled <strong>XL</strong> printer measurements with side spool holders and top enclosure cover (separate future add-on) are 800×800×900 mm | 31.49×31.49×35.43 in.</li>
<li>XL print volume: 360×360×360 mm | 14.17×14.17×14.17 in.</li>
</ul>
<p> </p>
<ul>
<li>An assembled <strong>MINI/+</strong> printer measures 320×330×380 mm | 12.6×13×15 in, and 5 kg.</li>
<li>MINI/+ print volume: 180×180×180 mm | 7×7×7 in.</li>
</ul>
<p> </p>
<ul>
<li>An assembled <strong>SL1S</strong> printer measures 225x237x400 mm | 8.8×9.3×15.7 in, and 11 kg.</li>
<li>SL1S print area: 127×80×150 mm | 5.0×3.1×5.9 in.</li>
</ul>
<p> </p>
<ul>
<li>An assembled <strong>SL1</strong> printer measures 220×240×415 mm | 8.7×9.45×16.3 in, and 11 kg.</li>
<li>SL1 print area: 120×68×150 mm | 4.7×2.6×5.9 in.</li>
</ul>
<div class="note-callout">Keep in mind that our MK-series and MINI/+ printers need some more space when in use. Especially in front of and behind them, as the heatbed is moving outside their footprint. More specific info is available specifically for your printer version, on its dedicated <a href="http://help.prusa3d.com/article/printer-handbooks_125045">handbook</a>. </div>
<div class="tip-callout">If you are building an enclosure, you can add even more space in every direction, for better access and manipulation. For the MMU, add 150 mm / 6 in, in height, and think about <a href="http://help.prusa3d.com/article/spool-placement_112035">where to put the 5 spools</a> (behind the printer or above).</div>
<h3>What is the printing precision/tolerance of the Original Prusa?</h3>
<p>According to our testing, the precision tolerance of a well-assembled Original Prusa printer is 0,1 mm on the Z-axis and 0,3 mm on X and Y. It can be as little as 0,05 mm on all axes, after making additional calibrations such as the Extrusion multiplier calibration and Extruder linearity correction.</p>
<p>However, please note that the material is also relevant: it can shrink while cooling down, and low-quality filaments with uneven diameters will cause uneven extrusion. The optimization of the model for 3D printing (overhangs, etc.) is also important. Our printers are tested even for the 0.25 mm nozzle, which is more precise compared to the standard/stock nozzle with a 0.4 mm diameter. </p>
<div class="tip-callout"><a href="https://manual.slic3r.org/troubleshooting/dimension-errors">This article</a> studies the accuracy of FDM printing in more detail.</div>
<h3>What tools do I need when working with my Original Prusa?</h3>
<p>All necessary tools (pliers, screwdriver, hex keys, wrenches…) are included in the package. If you are wondering what else you could need, here is a list of some nice-to-have things:</p>
<ul>
<li>3.5'' side-cutter/flush-cutter pliers</li>
<li>White permanent marker</li>
<li>Compressed air</li>
<li>A big bottle of IPA 91% to clean the sheet</li>
<li>Acetone (only with the smooth sheet)</li>
</ul>
<h3>What is the life expectancy of the printer?</h3>
<p>According to our testing, the average maintenance interval of our printers is around 800 print hours. When it needs to be serviced, most frequently, it’s the nozzle that needs to be changed, and then it can continue printing for many hundreds of hours more.</p>
<div class="note-callout">The ideal air temperature is from 20 - 30 °C (68 - 86 °F) and the ideal air humidity is 25 %.</div>
<h3>What is the power consumption of a PRUSA printer?</h3>
<p>The average power consumption that we have measured on an MK-series printer, at 26 °C (room temperature), is 80 W when printing generic PLA and 120 W when printing generic ABS.</p>


FAQ - Frequently Asked Questions

<p>Food-safe 3D printing is not as simple as it might seem. Here we outline some of the challenges. We also recommend you to check out <a href="https://blog.prusaprinters.org/how-to-make-food-grade-3d-printed-models_40666/">our blog article</a> where we present our research of the process.</p>
<h3>Materials</h3>
<p>PETG, and sometimes PLA, are hailed in the 3D printing community for being chemically neutral and as practically food-safe materials. Your soda plastic bottles, food containers, and salad boxes are made from PET, a close relative of PETG.</p>
<p>The problem, with all 3d-printed objects, in general, is that they are made from layers. The grooves in between those layers are a seedbed for bacteria as they are almost impossible to clean properly, and will hold residue.</p>
<p>Another issue is color-pigment and unknown additives. These might not be as neutral to your body as pure plastic. It is also hard to say exactly how much there is of these substances. Natural/pure PETG-filament without any color, would be your best bet, but it's hard to say exactly what is in it. Some filaments are FDA-approved, but often with an asterisk like "Approved except red, orange, and pink". In <a href="https://blog.prusaprinters.org/how-to-make-food-grade-3d-printed-models_40666/">our blog article</a> we map out which of our Prusament filaments you can and can not use.</p>
<div class="tip-callout">There are, however, food-safe certified epoxy coatings that you can apply to your printed model.</div>
<h3>Application</h3>
<p><strong>Waterbottle, no. Cookiecutter, maybe.</strong> There should not be much problem to 3d-print your own custom cookie-cutters, but as the layer-lines will collect food, bacteria will grow, so this will be something you want to throw away after some use.</p>
<p>The same goes for soap and detergent if you think you can just wash it. The layer lines can absorb these chemicals, which later can be released into something you want to consume.</p>
<h3>(M)SLA resin printers have practically no lines. Can't I use this?</h3>
<p>Again, no. There can be uncured resin and other contaminants on and in the print. There are bio-compatible resins out there, but these are highly specialized and very expensive. They also rely on special considerations when curing and in post-processing.</p>
<h3>Nozzle</h3>
<p>The nozzle you use also makes a difference. The standard brass nozzle is <strong>not considered food-safe</strong>, as it wears out. It is a consumable. Where does the worn material go? Into your print. Therefore, a soft brass nozzle just won't do. You would need a stainless-steel or a titanium nozzle if you are even considering printing with food in mind.</p>
<h3>So what can I do?</h3>
<p>There are epoxy resin coating-materials out there that have been deemed suitable. There is also the option of using 3d-prints simply as a mold with suitable materials and manufacturing methods. We have done some research and you can read more about food-safe 3D printing in <a href="https://blog.prusaprinters.org/how-to-make-food-grade-3d-printed-models_40666/">this blog article</a>.</p>
<h3>Conclusion</h3>
<p>It is theoretically possible, but special preparations and post-processing is required. If you really want to, it is not as simple as getting some PETG, and printing what you want. Do proper research, so you do not put anyone's health or safety at risk!</p>
<div class="warning-callout"><strong>We do not recommend using 3d-prints as food-containers etc!</strong></div>


Food safe FDM printing

<p>Every Original Prusa printer has a unique serial number assigned to it. This is found on a silver sticker on every machine and is also hardcoded to the main controller board. Serial numbers issued before November 2021 start with "<em>CZPX</em>", while after November 2021 we introduced a new format starting with "SN". All serials are registered in our internal database and they allow us to confirm your printer as genuine.</p>
<div class="tip-callout">For some printer models, placing the serial sticker on the frame is part of the <a href="http://help.prusa3d.com/guide/8-electronics-assembly_174100#175963">assembly process</a>!</div>
<div class="note-callout">The best way to reference your printer is the <strong>order number</strong> you received when purchasing the printer. This can be found on the invoice or in <a href="https://www.prusa3d.com/account/orders/">your order-history in the eshop</a>.</div>

<h4>Third-party purchases</h4>
<p>In case a printer was not directly purchased from our <a href="https://www.prusa3d.com/">e-shop</a>, the warranty is valid for <strong>one year</strong> from the date on which the printer was delivered originally (not the second-hand purchase). To use the warranty, make sure that you get from the seller the original invoice of the printer and make an <a href="https://account.prusa3d.com/">account in our e-shop</a>.</p>
<h3><strong>How to handle a warranty case</strong></h3>
<p>Any warranty case must be submitted to our official <a href="http://help.prusa3d.com/article/customer-support_2287">support channels (chat or email)</a>. In case the product was bought from a reseller, contact us first so that we can help you diagnose the problem, then turn to your reseller for spare parts if needed.</p>
<p><strong>Documentation needed</strong> for a warranty case:</p>
<ol>
<li>The number of the original invoice containing the product and the product's <a href="http://help.prusa3d.com/article/original-prusa-serial-number_134171">serial number</a>.</li>
<li>A brief description of the problem along with clear evidence of its presence (e.g., <a href="http://help.prusa3d.com/article/photo-and-video-documentation_112155">Photo and video documentation</a>).</li>

<h3>Notes about warranty</h3>
<ul>
<li>In case we have provided a free replacement part, the warranty does not reset. In compliance with European and Czech law, the original warranty period still applies.</li>
<li>In case you have sent a product back to us for repair, the warranty duration is "paused" while it is on its way back to us, in repair, and on its way back to you. In other words, the warranty is extended by the number of days that the product is gone for repair.</li>
<li>We do not have any agreement with any third-party Extended Warranty provider. If you are using such services, refer to the Terms and Conditions of your contract to see if and how it applies.</li>
</ul>
<h3>Limited warranty on consumables</h3>
<p>Some parts of our products inevitably "get used up" over time. For these parts, specific conditions apply, unless failure has occurred due to a defect in materials or workmanship.</p>

Warranty

<p>One of the best things about getting your very first 3D printer kit is the assembly. Building your first 3D printer may take some time, however, it's <strong>the perfect way</strong> to get to know the machine in detail. Not only that, but it's also a lot of fun to put the whole machine together.</p>
<p>The length of the assembly depends on the type of printer and generally takes several hours, complicated setups can take a day or two. However it is not a race, so take your time, follow the instructions, and <strong>enjoy the construction! </strong></p>
<h2>Our manuals </h2>
<ul>
<li>Our manuals are written in <strong>English, Czech, Spanish, Italian, German, French, and Polish. </strong></li>
<li>We try to make our manuals easy to understand so that truly everyone, from children to elderly persons can enjoy our printers. However, if you struggle with any chapter, do not hesitate to contact our <a href="http://help.prusa3d.com/article/customer-support_2287">customer support</a> at any time. </li>
</ul>
<h2>Common assembly errors </h2>
<ol>
<li>Do not rush with the assembly as going fast through usually means that some mistakes are made in the process. And it's more time-consuming to fix them than doing everything properly right from the start.</li>
<li>Once you see anything labeled in <span data-hd-color="rgb(192, 80, 77)"><strong>RED,</strong></span> always double-check that you followed these instructions correctly. These are usually essential steps in the whole assembly. Not following them might cause future problems, delays, and in the worst-case scenario even damage to the product.<br /><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/asdd.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/asdd-600x389.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/asdd-800x519.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/asdd-300x195.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/asdd-768x498.jpg 768w" width="674" height="437" loading="lazy" /></li>
</ol>
<h2>How hard can it be?</h2>
<ol>
<li>The complete assembly is quite straightforward if you follow the manual precisely. </li>
<li>Each chapter is labeled with a <strong>level of difficulty. </strong>That should give you an idea of what you can expect.</li>
<li><strong>Don't be afraid! Tens of thousands of users made it so you can make it too!</strong></li>
</ol>


<p>All of our printers come with an instructional Handbook. This is not merely a collection of tips and tricks but <strong>is the instruction manual for your machine.</strong> They cover everything in regard to your printer, from setup, calibration, slicing, printing, and troubleshooting. <strong>All handbooks are available in a range of languages.</strong></p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2025/02/613837c97859a1bd3ee9de43edda2784.jpg" sizes="(min-width: 1024px) 820px, 100vw" alt="" width="600" height="599" loading="lazy" /></p>
<p>The Handbooks are structured so you will not be thrown into the deep end of 3D printing, but will gradually learn how to best utilize your machine. Early on it even covers a glossary, as this technology brings with it a lot of its own terms and definitions, which are important to know, and progress from there.</p>
<p>This <a href="https://help.prusa3d.com/">knowledge platform</a> is an extension of these handbooks. For convenience, you will always be able to find the latest revision of the handbooks from this article.</p>

Printer Handbooks

<p>3D printing is an automated additive manufacturing-process, where a 3D printer creates a physical model based on digital data (a 3D object). All types of 3D printing are based on the same principle: creating objects by adding layers on top of (or below) existing layers. As of this moment, there is no 3D printing technology that would be completely universal and suitable for every purpose. This is why it's important to decide how and for what purpose you are going to use the printer.&nbsp;</p>

<h3>FDM/FFF printers</h3>
<p><strong>FDM</strong> is an acronym for <strong>Fused Deposition Modeling</strong> (trademark by Stratasys) and <strong>FFF</strong> stands for <strong>Fused Filament Fabrication</strong> (open source). It encompasses all 3D printers, which heat/melt polymers and push it through a nozzle/extruder/print head onto a platform, where the model is built. The material for printing is provided as filament spools of 1.75 mm or occasionally 2.85 mm in diameter. The differences in the types of printers out there lay in how the extruder and print platform move to create the models.&nbsp;</p>
<h4>Cartesian printers</h4>
<div class="note-callout">The <a href="https://shop.prusa3d.com/en/51-original-prusa-i3-mk3s">Original Prusa i3 printers</a> and the <a href="https://shop.prusa3d.com/en/3d-printers/994-original-prusa-mini.html">Original Prusa MINI</a> are Cartesian printers.</div>
<p>Cartesian printers are characterized by at least three motors moving the parts of the printer along the axes of the Cartesian coordinate system: Y (back and forth), X (left and right), and Z (up and down). Most personal desktop printers are Cartesian printers due to them being very widespread and low cost</p>
<p>The model to be printed needs to be sliced into layers for the print. The Y- and X-axis will define the coordinates to be printed in one layer, and once the layer is ready the Z-axis will make the nozzle move one layer up, either by moving the print-bed or by moving the extruder. If overhangs are present, supports can be added below them.</p>
<p>The biggest advantage of the Cartesian printers is how common they are. There are a lot of tips, tricks, and solutions for issues online. The parts for the printer can also be found easily.</p>
<p>On the downside, Cartesian printers, if used for faster prints, will have a lower quality of printing due to the weight of the axes. Also, usually, the printer volume is a lot larger than the build volume due to the movement of all of the axes.</p>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/Carthesian-printers.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/Carthesian-printers-300x165.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/Carthesian-printers-600x330.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/Carthesian-printers-768x423.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/Carthesian-printers-800x440.png 800w" alt="" width="667" height="367"></p>
<h4>CoreXY printers</h4>
<p>Like the Cartesian printers, the CoreXY design also has the latitudinal and longitudinal coordinates determined by two motors and timing belts on the Y- and X-axis, and the print height determined by the Z-axis. The difference of the Core XY is that the X and Y movement is dependent on each other, done by a very specific belt design. The print surface, in this case, will be lifted to meet the extruder. Note that not only the movable print surface makes a CoreXY printer. The defining trait for the printer type is the design of the XY-belts and their movement.</p>
<p>Since the X and Y axes are a lot lighter, faster prints will not have the artifacts that may appear on fast prints on Cartesian printers. The design also allows for a lot larger part of its overall volume to be the build-volume, since there is no need for the print surface to move sideways.</p>
<p>The belts used in CoreXY printers are a lot longer, which makes all belt issues bigger than with the Cartesian printers. Their complicated path also makes these issues harder to repair. The frame needs to be very stable and perfectly square, or else the dimensional accuracy will be smaller.</p>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/Corexy.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/Corexy-300x241.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/Corexy-498x400.png 498w" alt="" width="322" height="258"></p>
<h4>Delta printers</h4>
<p>In Delta printers, the print surface stands still, and three motors work together to meet in the hotend and move it with the latitudinal and longitudinal coordinates, as well as the height of it. These motors control three posts, and these posts are connected to the extruder by arms that will move the hotend. The name of the printer style (delta = Δ) comes from the triangular shape which the arms holding the hotend form. This type of printer was designed to make faster prints.</p>
<p>The Delta printer extruder is very light. That combined with the 3 motors controlling it, makes this printer ideal for fast prints. This printer was an early adopter of the 32-bit system due to the complex calculation it takes to make the movements. Some of the attraction of the printer is also how cool it looks while it is working.&nbsp;</p>
<p>The Delta printers all have a relatively small and circular print surface. This limits the build-space significantly. The high speed of the printer makes the prints less precise. Also, it is uncommon to be used as a desktop printer, as any issues that the printer has can be extremely difficult to troubleshoot and fix, not only due to complex working and lack of information but the overall lack and cost of parts. The printer also needs to work with a Bowden extruder to make the extruder light, which can limit the number of filaments that can be used.</p>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/Delta-printers.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/Delta-printers-300x194.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/Delta-printers-600x388.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/Delta-printers-768x496.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/Delta-printers-800x517.png 800w" alt="" width="690" height="445"></p>
<h4>Polar printers</h4>
<p>This printer uses the Polar coordinate system, which has the points on a circular grid instead of the square as the Cartesian system. The printing platform not only moves sideways but it also rotates. This allows the extruder to only move up and down, and also for a large build area. This printer has a very light frame.</p>
<p>This technology is still being developed. That makes the printer very expensive, and it makes parts and technical support hard to find when you have problems.</p>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/polar-printer.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/polar-printer-294x300.png 294w, https://cdn.help.prusa3d.com/wp-content/uploads/polar-printer-392x400.png 392w" alt="" width="401" height="409"></p>
<h3>SLA</h3>
<h4>(Stereolithography)</h4>
<p>The basic principle of <em>vat polymerization printing</em> is that a vat containing photosensitive liquid (resin) is cured layer by layer, by a heat source to make the object.</p>
<p>Printed objects are almost perfectly smooth, incredibly detailed and layers are nearly invisible to the human eye, with the minimal layer height going from 25 – 100 microns. The biggest disadvantage of this technology can be a smaller print surface area and also the toxicity of liquid resins. You should try to prevent resins from touching your skin and avoid inhaling resin vapors.</p>
<p>Printed objects are not fit for immediate use after the print job finishes since they tend to be a bit soft and sticky - which is caused by the leftover unsolidified resin on the surface of the object. It is recommended to wash the object in isopropyl alcohol and to cure it further using UV light.</p>
<div class="tip-callout">The <a href="https://shop.prusa3d.com/en/accessories/720-original-prusa-curing-and-washing-machine-cw1.html">Curing and Washing Machine (CW1)</a> is an optional accessory for our <a href="https://shop.prusa3d.com/en/52-original-prusa-sl1">Original Prusa SL1</a>, which can wash, dry, and cure the print quickly and easily.</div>
<h4>Masked Stereolithography (MSLA)</h4>
<p>Each layer's shape is displayed as a semi-transparent mask on an LCD screen, and the exposure is performed employing a high-performance UV LED. UV light can pass only through white pixels on the display. Due to the fixed resolution of the LCD display, the printed objects have a fixed XY resolution. This method also cures a whole layer at a time, meaning it doesn’t matter how many objects there are on the printing platform.</p>
<div class="note-callout">The <a href="https://shop.prusa3d.com/en/52-original-prusa-sl1">Original Prusa SL1 3D printer</a> uses this method.</div>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/print-msla.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/print-msla-300x90.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/print-msla-600x180.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/print-msla-768x231.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/print-msla-800x240.png 800w" alt=""></p>
<h4>Stereolithography (SLA)</h4>
<p>Exposure is performed by a UV laser ray. The ray is controlled by two mirrors and it “draws” each layer gradually. The time required to solidify a single layer depends on the size of the area which needs to be solidified. Simply put, the more objects there are on the print platform, the longer the print takes.</p>

<h4>Direct/digital Light Processing (DLP)</h4>
<p>The whole layer is solidified at once thanks to a digital projector. The areas that receive exposure from the projector are solidified. The advantage of this method is obvious - each layer is solidified in the same amount of time, no matter how many objects there are on the print platform.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/print-dlp.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/print-dlp-300x91.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/print-dlp-600x183.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/print-dlp-768x234.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/print-dlp-800x244.png 800w" alt=""></p>
<h3>SLS</h3>
<p><strong>Selective Laser Sintering</strong></p>
<p>Another type of 3D printing technology is SLS and DMLS, which use a process called <em>sintering</em>. Essentially, every time a new layer is printed, a cylinder spreads a thin layer of fine powder across the platform, which is then sintered with a laser into the required shape. When the print is finished, the whole object is covered with the printing powder. Due to how this method works, the printed objects must have holes, through which the excessive powder is poured out. Unsintered material can be reused for the next prints, which means that very little material is wasted. Another advantage is the fact that the layers are nearly invisible. These printers are not massively widespread among the common public. Due to their main use in various industries, the prices are noticeably higher - the cheapest machines start at around 6000 USD.</p>

<p>There are other types of technology and designs out there, like "Jetting" or concrete and metal printers, using various methods. Since those are mostly reserved for industrial applications due to price and patents, they are not included here.&nbsp;</p>


Types of printers and their differences

<p>Do you need to send your printer back for a refund or repair? Unlike when returning a single part or component, when returning an assembled Original Prusa i3 printer (MK2/S, MK2.5/s, MK3/S/+) you must follow some guidelines to prevent any damage during the transport.</p>
<div class="note-callout">In order to send any product back to us, always do so after an agreement with our <a href="http://help.prusa3d.com/article/customer-support_2287">Customer support</a>. Contact us on email <strong>info@prusa3d.com,</strong> or live chat where we are available 24/7.</div>
<h3>Returning for refund</h3>
<p>No matter the reason for returning the printer, <strong>if you are not sending it back for repair, you must include all of the tools and accessories</strong> that came with it. That includes:</p>
<ul>
<li>Flexible magnetic steel sheet</li>
<li>Spool of grey filament and spool holder (even if it has been opened and less than half is used)</li>
<li>SD card, power cable, USB cable</li>
<li>Pliers, spatula, screwdriver, Allen keys, spanner</li>
</ul>
<p>If we have sent you some replacement parts earlier, don't forget to <strong>send us back the original (broken) parts</strong> too.</p>
<div class="note-callout">The price of the damaged or missing items can be subtracted from your refund</div>
<h3>Returning for repair</h3>
<p>When returning the printer just for repair, you do not have to include everything.</p>
<p><strong>You can keep:</strong></p>
<ul>
<li>Tools (pliers, spatula, screwdriver, Allen key, spanner)</li>
<li>Cables</li>
<li>Spool holder</li>
</ul>
<p><strong>You must include:</strong></p>
<ul>
<li><strong>Flexible magnetic steel sheet.</strong> <em>If you have more sheets, always <strong>include</strong> <strong>the one that you are using when the problem happens</strong>.</em></li>
<li><strong>1 meter (40 inches) sample of the filament giving you trouble.</strong> <em>This is sufficient to check moisture content and diameter to eliminate these variables.</em></li>
<li><strong>SD card with the G-code and original STL file</strong> that you had trouble printing.</li>
</ul>
<h3>Documentation</h3>
<p>We require some documentation of the refund in the form of the following:</p>
<ul>
<li>Pictures of the packing process to have approved by our shipping department.</li>
<li>Prusa Service List: Download the <a href="https://www.prusa3d.com/downloads/others/PrusaServiceList_EN.pdf">Prusa Service List PDF</a> and fill out the form. It can be edited from the browser and should be sent with the photo documentation.</li>
</ul>
<h4>Serial number</h4>
<p>All printers have a serial number to identify them. This must be filled in when completing the Prusa Service List. This silver sticker is either <a href="http://help.prusa3d.com/article/original-prusa-serial-number_134171#original-prusa-mk-series">on the back of the printer's frame</a> or in the box that the Einsy board was sent. If you are missing this sticker and/or the serial, please contact support.</p>
<h3>List of packaging material</h3>
<h4>Cardboard box</h4>
<p>If you bought the printer assembled, please re-use the box in which you have received it. <strong>If it was a kit, please find another suitable box.</strong> The printer's dimensions are 420 × 420 × 380 mm (height). To accommodate for padding material and accessories the box must be a bit larger.</p>
<h4>The box should have a minimum volume of:</h4>
<p><strong>540 x 510 x 475 mm (height) / 21.5 × 20 × 18.5 inches.</strong></p>
<p>Make sure you use a box with thick enough cardboard. For reference, the walls of our boxes are 4 mm (~1/8 inch) thick.</p>
<h4>Zip ties</h4>
<p>You will also need some zip ties (also known as hose ties/cable ties) or similar fasteners. The smaller the length, the more you will need. We are always sending a full pack of zip ties with printer kits and upgrades.</p>
<div class="note-callout">If the zip ties are too short, remember you can always tie one zip tie to another.</div>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/DSC_0019.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/DSC_0019-300x225.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/DSC_0019-533x400.jpg 533w, https://cdn.help.prusa3d.com/wp-content/uploads/DSC_0019-768x576.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/DSC_0019-800x600.jpg 800w" alt="" width="391" height="294"></p>
<h4>Packaging material</h4>
<p>Protective padding material is important. Besides the official padding, the best is bubble wrap and crumpled-up paper, like old newspapers or ads. Layer this on top and around each component being packed.</p>
<div class="warning-callout">Foam peanuts or finely shredded paper are not suitable padding material!</div>
<p>To secure the nozzle, you will need a small piece of packaging foam of <strong>50 × 100 × 100 mm / 2 × 4 × 4 inches.</strong> For example, you can cut a piece of the white foam that was used in the original box. <em>Even if you purchased the printer as a kit, packaging foam can be found in the box where the motors were stored.</em></p>
<h3>How to pack the printer</h3>
<p><strong>Do not disassemble the kit! Do not try to cram the assembled kit into its original box! If you send us your kit for repair, partially (or fully) disassembled, you will be asked to pay the price difference between the kit and the assembled printer. Moreover, it can double the time needed to settle your claim.</strong></p>
<h4>MMU2S</h4>
<p>If you have a Multi-Material Upgrade, follow the guide linked below to correctly pack it before starting on the printer. Add it to the printer box when instructed to.</p>
<p><strong><a href="http://help.prusa3d.com/article/packing-multi-material-upgrade-for-return_177555">Packing Multi Material upgrade for return</a>&nbsp;</strong></p>

Packing i3 printer for return

<p>Pictures and videos are an important part of troubleshooting. When one of our agents is trying to help you with an issue, they often rely on pictures and videos to get a better understanding of the issue at hand. <strong>Photo and video documentation is also a part of our warranty terms.</strong></p>
<p>Therefore, we want to go through some advice and guidelines regarding shooting and sharing photo and video content.</p>
<div class="note-callout">There are security concerns regarding the sharing of files online. We will not download videos compressed into a Zip format, nor download files to our hard drive.</div>
<h3>Guidelines when shooting photos and video</h3>
<h4>The specific machine under troubleshooting</h4>
<p>Example pictures and screenshots from, for instance, our assembly manual, is of no assistance. We are helping you with your machine, so we need to see <strong>your specific machine.</strong> It is not helpful to see other printers, as there are always nuances to your specific case. Example: "Pictures in the third post of this forum thread is exactly like my issue" is unfortunately not sufficient.</p>
<h4>Well lit and in focus</h4>
<p>Make sure the object is well-lit and in focus before sending pictures or videos. On a small handheld screen it is not always obvious when important detail is missing, so zoom in to make sure, Also, use your camera's flash unless it burns out the picture.</p>
<h4>Super Close-up</h4>
<p>We often require general shots of “extruder” or ”frame” and with the resolution now available in modern handhelds there is rarely a need to go in very close, especially if it is well lit. Mostly it will end with you having to take and send more pictures.</p>
<h4>Camera orientation</h4>
<p>It is a common oversight to shoot video holding the phone in portrait orientation. The image chip in your phone’s camera always has its resolution in the same orientation as its screen, so when shooting video in this manner <strong>we lose about two-thirds of the resolution</strong> (illustration below) when it is displayed on a normal 'landscape' monitor. This removes detail important for the support agent. <strong>Please shoot video in Landscape orientation.</strong></p>

<h3>How to share</h3>
<h4>Cloud of your choice</h4>
<p>Both through email and Live Chat there is a 10 Mb data cap. Therefore, we often rely on your cloud services like Dropbox, Imgur, and Youtube to receive the material.</p>
<h4>Google Drive and Youtube</h4>
<p>Many of us use Gmail. With that, you have both access to Google Drive and Youtube. There are many guides out there on using Youtube. We found this clear and to-the-point guide from Wix.</p>
<ul>
<li><a href="https://www.wix.com/blog/2019/02/how-to-upload-video-youtube-guide/">https://www.wix.com/blog/2019/02/how-to-upload-video-youtube-guide/</a></li>
</ul>
<p>Regarding Google Drive, right-click the file, after uploading, and select "Get shareable link". In the dialog box that will open, make sure the option "Anyone with the link" is selected.</p>

<h4>Imgur</h4>
<p>Imgur is a site where you can upload photos without having an account. Per email and chat pictures are not really a problem, due to their small size, but it can be handy if you have a whole series of pictures. It also has good support for uploading directly from handhelds. wikiHow made a good guide on how to use this.</p>

Photo and video documentation

<p>Congratulations on your new <strong>assembled Original Prusa</strong> printer. For any first-time users, we have prepared this article and video for you who are just starting out with a Prusa 3D printer.</p>
<div class="warning-callout">This is complementary material to the bundled 3D Printing Handbook! <strong>Before switching the printer on, always carefully read the paper version of the 3D printing handbook,</strong> found in the box with your printer. The latest version of the Handbook is also available on our website in the <a href="https://www.prusa3d.com/drivers/">Drivers section</a>, in the right-hand column.</div>
<p style="text-align: center;"><iframe loading="lazy" src="https://www.youtube.com/embed/gebHvGyk--4" width="690" height="360" frameborder="0" allowfullscreen="allowfullscreen"></iframe></p>
<h3>Unpacking the printer</h3>
<ul>
<li><strong>Remove the "shipping helpers" (large foam pads)</strong> - The extruder and bed are secured by specially cut foam pads to secure these components during shipping. Remove them in this order:
<ul>
<li style="list-style-type: none;">
<ol>
<li>Remove the top piece.</li>
<li>Lift the printer out of the bottom piece (you can hold it by the frame).</li>
<li>Pull out the middle piece of foam, securing the extruder.</li>
</ol>
</li>
</ul>

</ul>
<h3>Calibrations</h3>
<p>An assembled printer is already calibrated so that you could start printing right out of the box. However, to account for any bumps the printer might have seen in transit to you, the printer will take you through the Z calibration the first time you start it up. This moves the X-axis to the top, pressing against the top of each Z-axis, to make sure it is the same on both sides.</p>
<p>This should be all the calibration necessary to start printing. However, different types of filament can act in different ways. You therefore should be aware of a couple of things.</p>
<ul>
<li><strong>The First Layer Calibration</strong> - Having the initial layer of your print too low or too high can cause issues with adhesion to the build plate or artifact/imperfection in your print. The nozzle can even clog if set too close. See our article on <a href="http://help.prusa3d.com/article/first-layer-calibration-i3_112364">how exactly your first layer should look</a>.</li>
<li><strong>Idler screw tension</strong> - The idler screw should generally be set so its head is about flush with the plastic part. However, some filaments, like flexible filaments, require this screw to be very loose. Moreover, if this screw is tightened all the way in, it can cause the motor pulling the filament to overexert itself. For more info see <a href="http://help.prusa3d.com/article/idler-screw-tension_177367">Idler screw tension</a>.</li>
</ul>
<h3>Handbook</h3>
<p>All of our printers come with an instructional Handbook. This is not merely a collection of tips and tricks but is the <strong>instruction manual for your machine.</strong> They cover everything in regards to your printer, from setup, calibration, slicing, printing, and troubleshooting. Even if you are not new to 3D printing we advise you to read this thoroughly. All handbooks are <a href="https://www.prusa3d.com/drivers/#driver-mk3s">available in a wide range of languages</a>.</p>


Unpacking an assembled i3 printer

<p>If the printer is being used in an area where the power grid has issues constantly, you might wish to install a <em>UPS</em> (Uninterruptible Power Supply) with the printer. UPS can compensate for power surges, voltage fluctuations, and temporary power loss.</p>
<p>Some considerations need to be made when purchasing the UPS.</p>
<h3>Power panic <em>(selected models only)</em></h3>
<p>The Original Prusa MK4/S, MK3.9/S, MK3.5/S, MK3/S/+, and XL printers are equipped with a <a href="http://help.prusa3d.com/article/power-panic_2092">Power Panic</a> feature, which recovers the print when the energy is back after a power outage. If power outages are constant, make sure to test the <a href="http://help.prusa3d.com/article/testing-safety-features-mk3-mk3s_2079#power-panic">Power panic</a>.</p>
<p>The power panic will work over multiple power outages, even if the printer is not re-started.</p>
<h3>Choosing a UPS for your printer</h3>
<p>If using a UPS is necessary, it is recommended to use a UPS that uses Line interactive technology. A Standby UPS will cause the printer to restart due to the higher triggering time.</p>
<p>A UPS is chosen based on the apparent power (VA) needed for the system. It is not recommended to use UPS smaller than 1000 VA for the printer.</p>
<p>Note that a UPS will not run your printer for a long amount of time. If a power outage lasts a long time, it is recommended to safely turn off the printer and start the print again after the power is back. For the printers with no Power Panic, the print will have to be started from the beginning.</p>
<h3>How long will the UPS power my printer?</h3>
<p>We have tested each printer using a Line interactive 1500 VA UPS. See below the information from each printer.</p>

UPS backup for your printer

<p>From both individuals and companies in the market for a 3D printer, our <a href="http://help.prusa3d.com/article/customer-support_2287">customer support</a> receives a lot of questions regarding our printers and what it takes to get started with 3D printing. We, therefore, made this addition to <a href="http://help.prusa3d.com/article/faq-frequently-asked-questions_1932">our FAQ</a>. We hope this guide can both provide some answers and assist in asking the right questions when purchasing a 3D printer. A side-by-side comparison of specs and numbers can not really inform such a decision. A 3D printer is a machine that can make almost anything you need, but the type of printer, material, and settings all depends on that need. </p>

<h4>Resin (MSLA) or plastic (FFF) printer? I hear resin printers have more detail.</h4>
<p>Yes, printers like the <a href="https://www.prusa3d.com/product/original-prusa-sl1s-speed-3d-printer-cw1s-bundle/">Original Prusa SL1S</a> do have more detail but also have a smaller build-area. Resins are hard and tough, but most are brittle when it comes to impact resistance. FFF (Fused Filament Fabrication) printers like the <a href="https://www.prusa3d.com/en/product/original-prusa-mk4-2/" target="_blank" rel="noopener">Original Prusa MK4</a>, <a href="https://www.prusa3d.com/product/original-prusa-mini-semi-assembled-3d-printer-4/" target="_blank" rel="noopener">Original Prusa MINI+</a>, or <a href="https://www.prusa3d.com/product/original-prusa-xl-assembled-5-toolhead-3d-printer/">Original Prusa XL</a> have a wider range of materials available and also a larger build-space. You can also do multi-material printing, using our <a href="https://www.prusa3d.com/category/original-prusa-mmu3/" target="_blank" rel="noopener">Original Prusa MMU3</a> (picture below), or one of the multi-tool versions of our Original Prusa XL.</p>

<h4>Why an Original Prusa printer?</h4>
<p>Our goal is to make 3D printing more accessible and embrace open standards. That means that all of our printers and software <a href="https://www.prusa3d.com/en/page/open-source-at-prusa-research_236812/" target="_blank" rel="noopener">are open-source</a>. We are continually working together with the community, listening to their feedback and ideas. Our aim is to deliver an outstanding 3D printer for an affordable price and make this amazing tool available not only to professionals but also to students and hobbyists. Therefore, we provide <a href="http://help.prusa3d.com/article/customer-support_2287">24/7 Support</a> for any questions regarding our machines and how to get started. In addition, we are developing this extensive <a href="https://help.prusa3d.com/">Knowledge Base</a>, to share our technical insights into 3D printing.</p>
<h4>What kind of setup do I need? </h4>
<p>This depends on your application and the number of printers. 1-2 printers can comfortably be in the same room as the operator, in for instance an office/studio setting. When printing PLA and PETG (two of the more common materials) there is minimal odor and noise. With a larger number of printers and/or manufacturing of ABS/ASA parts, it can be recommended to have a separate ventilated room or enclosure to avoid the noise and fumes this can produce. For Original Prusa MK3/S/+ and MK4, we offer our <a href="https://www.prusa3d.com/product/original-prusa-enclosure-3/">Original Prusa Enclosure</a>. </p>
<p>We also offer solutions for remote control and monitoring of our 3D printers, our <a href="http://help.prusa3d.com/article/prusa-connect-and-prusalink-explained_302608">Prusa Connect and PrusaLink</a>. </p>

<p>Our machines come both as pre-assembled or as a kit for self-assembly. The Kit comes with a <a href="http://help.prusa3d.com/article/assembly-manuals_2273">detailed illustrated assembly-manual</a> and is a great learning experience. The Original Prusa MK4 can take about 8-10 hours to fully assemble. The assembled printer just needs to be taken out of its box and after a quick setup, is ready to print.</p>
<h4>What materials can I work with and what should I use?</h4>
<p>Currently, our FFF 3D printers will work with almost any printing-polymer that has a printing temperature below 300 ºC, which includes 98% of the materials out there. The most accessible are <a href="http://help.prusa3d.com/article/pla_2062">PLA</a>, <a href="http://help.prusa3d.com/article/petg_2059">PETG</a>, and <a href="http://help.prusa3d.com/article/asa_1809">ABS/ASA</a>, but there are <a href="http://help.prusa3d.com/article/composite-materials-with-metal-or-wood-particles_166863">filaments infused with wood, copper-dust, steel, and much more.</a> Your choice of material depends on the application of the parts you will be printing. PLA and PETG cover most needs. Our support can help you with this if desired. For a beginner, a good rule of thumb is; PLA for pretty things and PETG for functional things. We have developed an extensive <a href="https://help.prusa3d.com/en/materials">Material guide</a> to assist in finding the correct material and how to print it.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2020/11/Screenshotn-material-guidescaled.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2020/11/Screenshotn-material-guidescaled-600x247.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2020/11/Screenshotn-material-guidescaled-800x329.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2020/11/Screenshotn-material-guidescaled-300x123.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2020/11/Screenshotn-material-guidescaled-768x316.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2020/11/Screenshotn-material-guidescaled-1536x631.jpg 1536w" alt="" width="800" height="329" loading="lazy" /></p>
<p>Our machines do not print metal, but the parts printed on our FFF printers can be made into metal through various methods. Moreover, there are robust polymers out there, like <a href="http://help.prusa3d.com/article/prusament-pc-blend_134211">Prusament PC Blend</a>, that could be a substitute, but if it is mainly metal components you need for your application, perhaps a FFF 3D printer is not what you need.</p>
<p>We also manufacture our own filament, <a href="https://prusament.com/" target="_blank" rel="noopener noreferrer">Prusament.</a> With its premium-grade materials and thorough testing, we a reaching a manufacturing precision of +-0.02mm, on 1.75mm filament. This makes it probably one of the best filaments in the world these days.</p>
<h4>What is the process from design to a finished print?</h4>
<p>This depends very much on the part, but simple objects like fittings, jigs, and cases for electronics can be quick for an experienced designer to make. We offer courses in our <a href="https://www.prusa3d.com/category/prusa-academy/">Prusa Academy</a> for 3D modeling, designing, and printing. </p>
<p>Printing time will also depend on the size and material of the part. In most cases, a print will be ready for use within 2-24 hours of printing.</p>
<p>Among <a href="http://help.prusa3d.com/article/where-can-you-get-3d-models_2179">multiple repositories of free 3D models</a>, we offer our own <a href="https://www.printables.com/">Printables</a> repository. </p>
<h4>How can you guarantee a good print quality?</h4>
<p>Rigorous testing and a large community dedicated to high print quality; We have one of the largest FFF print farms in the world with <a href="https://blog.prusaprinters.org/a-quick-look-to-our-printing-farm/" target="_blank" rel="noopener noreferrer">around 600 printers running 24/7</a>. We actually also hold the <a href="https://blog.prusaprinters.org/guinness-world-records-1096-original-prusa-3d-printers-running-at-the-same-time/" target="_blank" rel="noopener noreferrer">Guinness world record</a>, for the Most 3D printers operating simultaneously, with <strong>1096 3D printers operating at the same time in one room.</strong> </p>
<p>This experience and our beloved community spread across <a href="https://forum.prusaprinters.org/" target="_blank" rel="noopener noreferrer">forums</a> and social media, in multiple languages, keeps us on our toes, and assure we know how our designs work on a large scale. Our printers are also by large manufactured using our own printers, so we too rely on their reliable operation. With all of the plastic parts on the printer being 3D printed, we are able to iterate quickly and <a href="http://help.prusa3d.com/article/printable-parts-for-original-prusa_1824">provide upgrade-options our users can print themselves.</a></p>
<p>We also develop and update presets and printing profiles for our open-source software, PrusaSlicer. More on that later on.</p>
<h4>What kind of training/expertise is required?</h4>
<p>There is a lot to learn, but the learning curve is gentle, and anyone can be printing with little effort. We strive to make it as smooth as possible. Our printers come with a <a href="http://help.prusa3d.com/article/printer-handbooks_125045">detailed instructional handbook</a> and we provide extensive documentation through our courses from our <a href="https://www.prusa3d.com/category/prusa-academy/">Prusa Academy</a>, through the <a href="https://help.prusa3d.com/">platform you are now reading</a>, <a href="https://blog.prusa3d.com/">our blog</a>, and our <a href="https://www.youtube.com/channel/UCLHAxAdvAKJY0niRJZRYMvg">YouTube channel</a>, informing on every aspect of our machines and 3D printing in general. Our <a href="http://help.prusa3d.com/article/customer-support_2287">customer support</a> team can also help you with any technical questions or issues.</p>
<h4>Does the printer come with any software and can I test it?</h4>
<p>Our slicer software PrusaSlicer is <a href="https://github.com/prusa3d/PrusaSlicer">free and open-source</a> and can be <a href="https://www.prusa3d.com/prusaslicer/">downloaded here</a>. It is a powerful tool to convert your 3D models into a format the 3D printer can read (G-code). Getting started is as easy as importing your model and exporting the G-code, using our presets. If you need something more specific for your application, PrusaSlicer has <a href="http://help.prusa3d.com/article/faq-prusaslicer_1789">a lot of advanced features</a> like custom supports, hollowing of models, modifier-meshes, and more. You can even do some basic 3D modeling. It is also <a href="http://help.prusa3d.com/article/general-info_1910">fully documented</a>.</p>

<p>However, we do not develop dedicated modeling/CAD software, but we <a href="http://help.prusa3d.com/article/creating-your-own-3d-models_2209">do have some information on it.</a> We are avid users ourselves, after all, but the choice of software is so much down to personal preference and experience level. There is a great amount of 3D programs out there, from free to very expensive. Your choice depends on your needs, but if you are just starting out you should look to something with a large user base or community. Then you will probably find a tutorial for most operations and tasks, or be able to ask the community for help and advice.</p>


FAQ - Extended buyers-guide

<p>Prusameters is our unique reward system on <a href="https://www.printables.com/" target="_blank" rel="noopener">Printables.com</a>.</p>
<p>You can collect Prusameters for various actions and achievements. Prusameters then can be exchanged for a real spool of Prusament filament and various other physical rewards.</p>
<div class="note-callout"><strong>The process is as follows</strong>: Collect enough Prusameters =&gt; Choose a reward =&gt; Wait for the approval and sending of the voucher =&gt; Redeem the voucher in the e-shop</div>
<h4>Prusameters and physical rewards</h4>
<p>Every user gets an empty virtual spool of Prusament, which is displayed in the top right corner next to your avatar on Printables.com. By performing various activities, you can fill up the spool with special points called Prusameters.</p>
<p>When you upload a new model, the system starts tracking its performance (downloads and likes) over a 30-day period. There are up to four milestones you can hit during this period. For each consecutive milestone, you’ll get a higher amount of Prusameters. Once the 30-day period ends, the internal counters are reset but the earned Prusameters remain in your account. </p>
<p>There are four milestones you can hit with your models <strong>repeatedly</strong> every 30 days:</p>
<p>10 Prusameters for 30 downloads and 3 likes of your model<br />50 Prusameters for 100 downloads and 10 likes of your model<br />100 Prusameters for 200 downloads and 15 likes of your model<br />200 Prusameters for 400 downloads and 20 likes of your model</p>
<p>You can also get <strong>non-recurring</strong> rewards for these actions:</p>
<p>20 Prusameters for completed profile - avatar, bio, location, languages<br />10 Prusameters to publish a model. Up to 10 new models in total.<br />5 Prusameters to create a collection. Up to 3 non-empty collections.<br />From 1 to 10 Prusameters to upload a make. Up to 100 Prusameters per calendar month.</p>
<div class="tip-callout">We appreciate it if you add a quality rating and upload makes regularly. A make of a model that already has many makes is rewarded with fewer Prusameters. You are not rewarded for the make of your own model, and for the second and subsequent makes of the same model.</div>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/01/Prusameters.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="How do Prusameters on Printables work?" alt="" width="600" height="401" /></p>
<p>Your virtual spool will become visually full at <strong>350 Prusameters</strong>, however, there’s no limit on how many Prusameters you can earn in total. The number we’ve picked is not accidental – 350 meters of filament is exactly what you can find on a real spool of Prusament. So, it only makes sense that 350 Prusameters is what you need to get a voucher for a 100% discount on a real spool of Prusament PLA, PETG, or ASA.</p>
<p>The vouchers are being approved manually to prevent abuse of the reward system. It can therefore take up to 2 weeks before they are approved and sent to you. Only one voucher per order can be applied.</p>
<div class="warning-callout">Please note that once you exchange Prusameters for a voucher, that voucher is bound to the selected rewards and cannot be changed to a different type of reward. It also cannot be changed back to Prusameters.</div>
<p>You can find the current list of available rewards on the <a href="https://www.printables.com/prusameter/rewards">Printables Rewards page</a>. When you choose the reward you want, you’ll receive a voucher for our e-shop that will get you a 100% discount on the selected item.</p>
<h4>Example of Prusameter reward calculation</h4>
<p>Let’s say you upload a new model and it reaches 300 downloads and 30 likes during one of the 30-day periods. This grants you a total of 160 Prusameters:</p>
<p>10 points for the first milestone (30 downloads and 3 likes)<br />50 points for the second milestone (100 downloads and 10 likes)<br />100 points for the third milestone (200 downloads and 15 likes)</p>
<div class="tip-callout"><strong>Tips to avoid voucher request rejection:</strong></p>
<p>1) Upload only models that you designed or remixed<br />2) Upload quality photos of your own makes<br />3) The model in the make photo must match the 3D model<br />4) Don't upload an excessive amount of makes of miniature few-gram models<br />5) Do not upload the photo to multiple different models</p>

How do Prusameters on Printables work?

<p>3D printers have their own vocabulary and words for describing their various parts and functions. If you are doing maintenance or about to seek help online, it is necessary to have the right words to describe your issue or problem. We have put together a list of words with explanations, covering most parts on the printer.</p>
<h4 style="text-align: center;">This glossary covers Original Prusa MK3, MK3S, MK2, MK2S, MK2.5S and MK2.5</h4>
<div class="tip-callout">You can identify all parts of the MK3 and MK3S using the <a href="http://help.prusa3d.com/article/360-viewer_1877">360 viewer</a>.</div>
