<h3>Basic info</h3>
<div><strong>PETG</strong> is one of the most easily printable materials, it is <strong>inexpensive and suitable for beginners</strong>. Relatively high tenacity and temperature resistance make it <strong>suitable for printing technical parts</strong> (for example parts of our printers).</div>
<div>&nbsp;</div>
<div><strong>Recommended nozzle temperature:</strong> 230 °C for the first layer, 240 °C for the other layers</div>
<div>&nbsp;</div>
<div><strong>Recommended bed temperature:</strong> 85 °C for the first layer, 90 °C for the other layers</div>
<div>&nbsp;</div>
<div><strong>Heatbed:</strong> Using powder-coated TXT or satin sheet is highly recommended. Printing on smooth PEI surface might damage the sheet.</div>
<h3>Description</h3>
<div>
<p><a href="https://www.prusa3d.com/category/prusament-petg/"><strong data-stringify-type="bold">PETG</strong></a> (Polyethylene Terephthalate modified with Glycol) is a commonly used technical material, popular among 3D printer users for its <strong>low price and good printability</strong>. It’s tenacious, with good temperature resistance; PETG is most commonly used for printing various mechanical parts, holders, clamps, and waterproof parts (thanks to great layer adhesion).</p>
<p>PETG has a glossy surface, adheres greatly to a print sheet, and <strong>does not shrink or warp</strong> (it has very little thermal expansion), therefore it’s suitable for printing large models. Plus, its high tenacity and flexibility often <strong>prevent it from breaking.</strong> Due to good temperature resistance, PETG parts are suitable both for interior and most exterior use (with temperatures below 80 °C). <strong>Parts of our printers are made of PETG!</strong></p>
<p>The letter G in PETG means that it’s modified with glycol during the manufacturing process. Glycol makes PET less brittle, easier to print, and more transparent for translucent prints. Of course, you can print also with PET filaments without glycol. However, printing with only PET is challenging and does not offer any advantage whatsoever.</p>
<div class="warning-callout">Even though PETG in itself may be considered <a href="http://help.prusa3d.com/article/food-safe-fdm-printing_112313">food-safe</a>, it consists of layers, as every 3D print, in which bacteria can grow over time. You can prevent this by applying a <strong>food-safe(epoxy) coating.</strong> Also, a stainless-steel nozzle should be used for if food is the intended application.</div>
<p>Although <strong>PETG</strong> is frequently used in <strong>food industry</strong> and is considered <strong>food-safe</strong>, we do not recommend it (or any other filament) for printing dishes or other stuff that comes into direct contact with food. The main reason is tiny print layer surface grooves that can support numerous bacterial colonies. But if you still want 3D printed dishes, we suggest <strong>applying a special layer</strong> that seals the surface (food-safe coating) and printing with a clean steel nozzle.</p>
<p>Some of the manufacturers <strong>enrich PETG with various additives</strong> and sell these materials under different names. For example, Spoolworks EDGE by E3D is modified PET/Copolyester Blend with additives. The goal is to acquire better visual qualities, surface and layer adhesion, etc.</p>

<h3>Best use</h3>
<p>PETG is used universally but is especially suitable for mechanical parts for both indoor and outdoor use. We use PETG to print parts for our printers! Plastic bottles are also made from this kind of material.</p>
<h3>Tips for successful printing</h3>
<p><strong>Temperature settings and cooling</strong></p>
<p>Unlike PLA, <strong>PETG requires a heated bed (85 °C).</strong> Its bridging- and overhang-behavior is usually worse, plus it is prone to stringing. Stringing can be moderated with higher retractions and lower nozzle temperature, but we suggest <strong>using the PrusaSlicer profiles that should work fine.</strong> It’s important to <strong>cool the PETG print</strong> - this helps to keep the model detailed and prevents stringing and oozing. But if you want the model to be as tough as possible, try to turn off the print fan. Higher filament temperature improves merging between layers which leads to better mechanical resistance. Otherwise, we recommend printing the first few layers with the print fan off to prevent deformation, then with the fan running at half its power.</p>
<div class="warning-callout"><strong>Do not print on the smooth PEI sheet</strong> as the adhesion may be too strong!</div>
<p><strong>Print surface preparation</strong></p>
<p>Make sure the print surface is clean, as described in <a href="http://help.prusa3d.com/article/first-layer-issues_1804">our dedicated article</a>. It is advisable to use one of the <strong>powder-coated print sheets. Do not print on the smooth PEI sheet</strong> as the adhesion may be too strong! If you decide to use the smooth PEI sheet anyway, apply a glue stick on it before printing.</p>
<p><strong>Adding more perimeters for more solid parts</strong></p>
<p>If you want to print truly solid parts, <strong>try to increase the number of perimeters</strong> instead of adding more infill.</p>
<h3>Postprocessing</h3>
<p>PETG can be easily sanded both dry and wet.</p>
<p><strong>Dissolving PETG</strong></p>
<p><strong>Dissolving and smoothing PETG</strong> is possible only in a laboratory by skilled lab workers using <strong>dangerous chemicals</strong> (Dichloromethane).</p>

PETG

<p>Loose belts would cause a printer to malfunction and prevent proper printing. It can cause <a href="http://help.prusa3d.com/article/layer-shifting_2020">Layer shifting</a>, <a href="http://help.prusa3d.com/article/ghosting_1801">Ghosting</a>, or other print abnormalities like getting an irregular shape instead of a perfect circle when printing a cylinder. <strong>The Y-axis belt is located under the heatbed, X-axis belt moves the print head. All adjustments are done with the 2.5mm Allen key. </strong></p>
<h3>Checking belt tension</h3>
<h4>New procedure - Belt tuner app</h4>
<p>For checking the belt tightness using our <a href="https://belt.connect.prusa3d.com/">belt tuner</a>, follow the instructions in the video below.</p>
<p style="text-align: center;"><iframe src="https://www.youtube.com/embed/oeq2MVxE_H8" width="560" height="314" allowfullscreen="allowfullscreen" loading="lazy"></iframe></p>
<h4>Old procedure</h4>
<p>On MK3/S/+, run the Self-test or the Belt test, from Calibration on the LCD. Then check <em>LCD-menu -&gt; Support -&gt; Belt-status.</em> You want the number between <strong>260 and 290 (275~)</strong>. <em>The lower the number, the tighter the belt is. Imagine it is a fictive count of teeth in circulation.</em></p>
<div class="tip-callout">For the MK2.5 and MK2.5S, a great way to check whether your belt is at the correct tension is to print this <a href="https://www.prusaprinters.org/prints/46639-tension-meter-for-the-gt2-belts-of-i3-mk3s-or-prus">Tension Meter for the GT2 belts</a>.</div>
<p>Another way is to use the technique described in <a href="http://help.prusa3d.com/guide/5-e-axis-assembly_28536#30816">this step</a> of the assembly manual to test if the pulley is correctly tightened and if the belt is not too loose. Hold the X-axis motor shaft with pliers (take advantage of the flat part of the shaft) to fix it in place (<strong><span style="color: #b96ad9;">purple circle</span></strong>), then try to move the extruder by hand. <strong>You should see no slack on the belt as a result of pushing on the extruder.</strong> The same procedure can be applied to test the Y-axis pulley and belt.</p>

<h3>X-axis belt</h3>
<h4>Slight adjustments MK3S</h4>
<p>Loosen the two front-facing screws and make sure they have space to their right to move (<span style="color: #f1c40f;"><strong>yellow circles</strong></span>). While assisting with the rotation of the motor with your hand, tighten the M3x18 screw on top of the X-end-motor (<span style="color: #b96ad9;"><strong>purple arrow</strong></span>).</p>
<p>After each turn or two check the tension in the belt by pressing them together. For optimal performance, the belt must need some force to press together with your fingers (<span style="color: #2dc26b;">green arrows</span>). <strong>Move the extruder all the way to the X-end-idler and try the belt tension in the middle of the X-axis.</strong></p>

<h4>Slight adjustments MK3S+, MK4</h4>
<ol>
<li>Slightly release all the screws holding the motor, otherwise, the "tensioner" won't work as the motor must be able to move (left picture).</li>
<li>Using the ball end of the Allen key, start tightening the screw on the rear side of the X-end-motor, but after each turn or two check the tension in the belt (right picture).</li>
<li>When you achieve optimal tension, please tighten the screws again (left picture).</li>

<h4>Large adjustments MK3/S/+</h4>
<p>If a slight adjustment is not sufficient you must adjust it at the belt holder. This is found on the back of the extruder and requires a little disassembly.</p>
<p>First, remove the two top screws from the motor-holder to let the belt have some slack in order to easier manipulate the belt.</p>
<ol>
<li>Snip the zip-ties on the back of the extruder (<span style="color: #e03e2d;"><strong>red arrows</strong></span>), which are securing the hotend wires <strong>and</strong> the ones securing the cable wrap.</li>

<h3>Y-axis belt</h3>
<h4>Slight adjustments</h4>
<p>On the front plate of the printer's frame, behind the LCD module, you will find the printed Y-axis belt idler. This is held by two M3X10 screws (<span style="color: #b96ad9;"><strong>purple arrow</strong></span>), going through the front plate.</p>
<p>If you have a gap between the idler part and the front plate of the frame (<span style="color: #236fa1;"><strong>blue arrows</strong></span>) you can tighten the belt by using your 2.5 mm Allen key to turn the screws clockwise (<span style="color: #b96ad9;"><strong>purple arrow</strong></span>), closing the gap.</p>
<p>The easiest way to access the screws is from below, by moving the printer to the edge of its table, with the LCD module sticking out. You now have access to the bolts from below the LCD module.</p>

<h4>Large adjustments</h4>
<p>If a slight adjustment is not sufficient you must adjust it at the belt holder. There are two main types of the Y-axis belt holder, one adjustable and one fixed. The adjustable belt holder was introduced in the first quarter of 2019, with the S-upgrade for the Original Prusa MK3, and is also featured on the Original Prusa MK4. Adjustments for this are explained in '<strong>Method 1</strong>'. For an earlier Original Prusa MK3, follow '<strong>Method 2</strong>', for the fixed belt holder.</p>
<h4>Method 1 - Adjustable belt holder</h4>
<div class="tip-callout">The Original Prusa MK4 has a different design than in the pictures, but the procedure is the same. </div>
<ol>
<li>Unplug the printer and lay it over on the side of the PSU.</li>
<li>Below the bed carriage, you will find the belt holder. Loosen the right screw by turning it <strong>counterclockwise</strong> (<span style="color: #e67e23;"><strong>orange circle</strong></span> left picture).</li>
<li>Turn the screw going through the two halves of the belt holder (<span style="color: #b96ad9;"><strong>purple arrow</strong></span> right picture). Turn <strong>clockwise</strong> to tighten the belt, moving the two halves together (<span style="color: #236fa1;"><strong>blue arrows</strong></span>).</li>
<li>When at the correct tension, secure the right half of the belt holder again by turning the screw from step 2 clockwise (<span style="color: #e67e23;"><strong>orange circle</strong></span> left picture).</li>

Adjusting belt tension (MK3/MK3S/MK3S+/MK4)

<p>Every FFF (Fused Filament Fabrication) printer requires a First Layer Calibration, which <strong>sets the vertical "Z" distance between the nozzle and the print surface</strong>. Sometimes this value needs <strong>a slight adjustment</strong> and for this situation, there is an option called "<strong>Live adjust Z"</strong> <em>(as you are mostly tuning it live during the first layers of your print).</em> The reason for adjusting the distance is to mostly <strong>provide better adhesion</strong> of the extruded filament.</p>
<h3><strong>How does it work?</strong></h3>
<p>It is important to know the following:</p>
<ul>
<li>the default value before the First layer calibration starts at zero (0.000) for all printers</li>
<li>to get <strong>closer to the print surface</strong>, turn the knob <strong>counter-clockwise</strong> and further <strong>increase the negative value</strong> (e.g. -0.500 =&gt; -0.600 =&gt; -0.700...)</li>
<li>to get <strong>further from the print surface</strong>, turn the knob <strong>clockwise</strong> and continue <strong>lowering the negative value</strong> (e.g. -0.700 =&gt; -0.600 =&gt; -0.500...)</li>
</ul>
<p>The values of the <em>Live adjust Z</em> are typically in the range of -1.500 to -0.200. Going above zero into the positive values is not possible, this indicates either an issue with the measuring sensor (M.I.N.D.A., P.I.N.D.A., SuperPINDA) or incorrect alignment.</p>
<p>The correctly assembled print head has <strong>the sensor always slightly above the nozzle</strong>, never at an equal level or below the nozzle (see the picture below). <em>The exact position can slightly vary, use the last chapter of the assembly manual of your printer to set the rough distance.</em></p>
<p style="text-align: center;"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/XYZ-Calibration-MK3-and-MK3S-04.jpeg" alt="" width="718" height="350" loading="lazy" /></p>
<p style="text-align: center;"><em>Example of the MK3S extruder</em></p>
<h3>Live Adjust Z (while printing)</h3>
<p>The most common approach is to perform the <em>Live adjust Z</em> during the print. Go to <em>LCD Menu -&gt;</em> <span style="color: #000000;" data-hd-color="#000000" data-hd-highlight=""><em>Live adjust Z.</em></span> This will show the <span style="color: #000000;" data-hd-color="#000000" data-hd-highlight=""><em>Live adjust Z</em></span> value you have set in the First layer calibration. From here you can adjust it by rotating the knob.</p>
<p>The <strong>Original Prusa MK4</strong> and <strong>Original Prusa XL</strong> are equipped with a loadcell, which will calibrate the first layer automatically. In case you would still like to fine-tune it, you can long-press the knob while the first layer is printed.</p>
<p><img decoding="async" style="max-height: 300px; display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-1-1.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-1-1-600x194.jpg 600w, https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-1-1-800x258.jpg 800w, https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-1-1-300x97.jpg 300w, https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-1-1-768x248.jpg 768w, https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-1-1.jpg 1600w" width="600" height="194" loading="lazy" data-hd-height="300px" data-hd-align="center" /></p>
<p style="text-align: center;"><em>Example of the MK3S menu</em></p>
<div>
<div class="tip-callout">PRO tip: shortcut from the main screen, while printing the first few layers press and hold the knob for a few seconds to access the <em>Live adjust Z</em> screen.</div>
</div>
<div>
<div class="warning-callout"><strong>Adjusting Live adjust Z value while printing is permanent</strong>, not only for the ongoing print! The new value will also remain after you turn OFF the printer.</div>
</div>
<div>In the picture below you can see examples of different <em>Live adjust Z</em> values. If the nozzle is too high from the surface, the filament won't stick properly (left), if the nozzle is too close to the surface, the filament won't be able to "flow out" leading to a potential clog of the nozzle (right).</div>
<p><img decoding="async" src="https://help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-04.jpg" alt="" width="1132" height="450" loading="lazy" /></p>
<h3>Live Adjust Z (before the print)</h3>
<p>You can also change the value while the printer is at rest from <em>LCDMenu -&gt; Settings -&gt; Live adjust Z.</em> You will see the value set previously during the First layer calibration, and from here you can adjust it by rotating the knob.</p>
<p><img decoding="async" style="max-height: 300px; display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-2.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-2-600x194.jpg 600w, https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-2-800x258.jpg 800w, https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-2-300x97.jpg 300w, https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-2-768x248.jpg 768w, https://help.prusa3d.com/wp-content/uploads/2022/05/Live-adjust-z-2.jpg 1600w" width="600" height="194" loading="lazy" data-hd-height="300px" data-hd-align="center" /></p>
<p style="text-align: center;"><em>Example of the MK3S menu</em></p>
<p><strong>The Live adjust Z should be used only to fine-tune the distance</strong>. For example, PETG and other high-temperature materials require to be squished in the surface slightly more as they tend to warp (lift up), compared to the PLA. If you have replaced the sensor or disassembled the print head (extruder) you should run the <a href="http://help.prusa3d.com/article/first-layer-calibration-i3_112364">First Layer Calibration (i3)</a> instead.</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's frame signed by Jo?</h3>
<p>Josef can sign the frame, 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.</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>Mini</strong> printer has 12.6 × 13 × 15 inch / 320 × 330 × 380 mm and 5 kg</li>
<li>Mini print area: 7×7×7 inch / 180 × 180 × 180 mm</li>
</ul>
<p> </p>
<ul>
<li>An assembled <strong>SL1</strong> printer has 8.7 × 9.45 × 16.3 inch / 220 × 240 × 415 mm and 11 kg</li>
<li>SL1 print area: 4.7 × 2.6 × 5.9 inch / 120 × 68 × 150 mm</li>
</ul>
<p> </p>
<ul>
<li>An assembled <strong>i3</strong> (MK2/3) printer itself has 16.5 × 16.5 × 15 inches / 420 × 420 × 380 mm and 7 kg</li>
<li>MK3/S print area: 9.8 × 8.2 × 8.2 inches / 250 × 210 × 210 mm</li>
</ul>
<div class="note-callout">Keep in mind that the mini and all i3 printers need some more space when in use. Especially in front of and behind them, as the heatbed is moving outside their footprint. Count with 19.7 × 21.5 × 21.5 inches / 500 × 550 × 450 mm (400 × 450 × 450 mm for the Mini), without the spool or MMU.</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, at 26 °C (room temperature), is 80 W when printing generic PLA and 120 W when printing generic ABS.</p>
<p> </p>

FAQ - Frequently Asked Questions

<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://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-01.jpg" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-01-300x293.jpg 300w, https://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://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-02V3.jpg" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-02V3-600x238.jpg 600w, https://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-02V3-800x317.jpg 800w, https://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-02V3-300x119.jpg 300w, https://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://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-300x288.png 300w, https://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-417x400.png 417w, https://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-03-768x737.png 768w, https://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://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-04-166x300.png 166w, https://help.prusa3d.com/wp-content/uploads/SD-cards-and-USB-flash-drives-04-222x400.png 222w" src="https://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>

<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>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 the printer and generally takes several hours, complicated setups (e.g. MK3S + MMU2S) can day or two. However it is not a race, so take your time, follow the instructions and <strong>enjoy the construction!&nbsp;</strong></p>
<h2>Our manuals&nbsp;</h2>
<ul>
<li>Each <strong>kit</strong> comes with a printed assembly manual (<strong>MMU2S assembly manual is only available online</strong>). If you would like to see the photos in full resolution, you can always visit <a href="https://help.prusa3d.com/en/category/assembly-manuals_272">our online manuals</a>. Choose the language and product you are assembling. Pay attention to your <strong>printer version</strong> (e.g., MK3 assembly differs from the MK3S).</li>
<li>Our manuals are written in&nbsp;<strong>English, Czech, Spanish, Italian, German, French, and Polish.&nbsp;</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 support at <a href="mailto:info@prusa3d.com">info@prusa3d.com</a>.&nbsp;</li>
</ul>
<h2>Common assembly errors&nbsp;</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&nbsp;<span data-hd-color="rgb(192, 80, 77)"><strong>RED,</strong></span>&nbsp;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 />

</ol>
<h2>How hard can it be?</h2>
<ol>
<li>The complete assembly is quite straightforward if you follow the manual precisely.&nbsp;</li>
<li>Each chapter is labeled with a&nbsp;<strong>level of difficulty.&nbsp;</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>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://help.prusa3d.com/wp-content/uploads/Carthesian-printers.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/Carthesian-printers-300x165.png 300w, https://help.prusa3d.com/wp-content/uploads/Carthesian-printers-600x330.png 600w, https://help.prusa3d.com/wp-content/uploads/Carthesian-printers-768x423.png 768w, https://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://help.prusa3d.com/wp-content/uploads/Corexy.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/Corexy-300x241.png 300w, https://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://help.prusa3d.com/wp-content/uploads/Delta-printers.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/Delta-printers-300x194.png 300w, https://help.prusa3d.com/wp-content/uploads/Delta-printers-600x388.png 600w, https://help.prusa3d.com/wp-content/uploads/Delta-printers-768x496.png 768w, https://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>

<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://help.prusa3d.com/wp-content/uploads/print-msla.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/print-msla-300x90.png 300w, https://help.prusa3d.com/wp-content/uploads/print-msla-600x180.png 600w, https://help.prusa3d.com/wp-content/uploads/print-msla-768x231.png 768w, https://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>
<p><img decoding="async" src="https://help.prusa3d.com/wp-content/uploads/print-sla.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/print-sla-300x87.png 300w, https://help.prusa3d.com/wp-content/uploads/print-sla-600x174.png 600w, https://help.prusa3d.com/wp-content/uploads/print-sla-768x223.png 768w, https://help.prusa3d.com/wp-content/uploads/print-sla-800x232.png 800w" alt=""></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://help.prusa3d.com/wp-content/uploads/print-dlp.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/print-dlp-300x91.png 300w, https://help.prusa3d.com/wp-content/uploads/print-dlp-600x183.png 600w, https://help.prusa3d.com/wp-content/uploads/print-dlp-768x234.png 768w, https://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><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/SLS-printers-650x432-min.jpg" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/SLS-printers-650x432-min-300x199.jpg 300w, https://help.prusa3d.com/wp-content/uploads/SLS-printers-650x432-min-600x400.jpg 600w" alt="" width="459" height="306"></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>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>

Payment options

<p>If your printer has an issue you cannot solve by troubleshooting remotely with our <a href="http://help.prusa3d.com/article/customer-support_2287">Customer support</a>, it is possible to send the printer to be repaired by one of our technicians.</p>
<h3>Repair within warranty</h3>
<p>If you have a <strong>pre-assembled</strong> printer, the cost of sending the printer for repair is covered by your warranty.</p>
<p>If you have a <strong>kit</strong> version of the printer, only the individual parts are covered by the warranty, not the repair. If you wish to send the printer for repair, the shipping and service will be charged even within the warranty.</p>
<p><strong>You can read more about the warranty claims here: <a href="http://help.prusa3d.com/article/warranty_2288">Warranty</a>.</strong></p>
<div class="warning-callout">Note that if a user error is found during the warranty repair, the parts and return shipping will be charged!</div>
<h3>Repair out of warranty</h3>
<p>If your printer was purchased as a kit or you have an assembled printer out of warranty, you may wish for a repair at our facility. Start by contacting our <a href="http://help.prusa3d.com/article/customer-support_2287">Customer support</a> with details of the issue.</p>
<h3>Procedure</h3>
<p>When a repair service is requested, an email will be sent within a few days with instructions for the return process. A <a href="https://www.prusa3d.com/downloads/others/PrusaServiceList_EN.pdf">Service list</a> must be filled by the user of the printer with the report of the issue.</p>
<p>When the printer is received it will be evaluated, and an initial diagnostic will be made on the hardware, function of the printer, and the Service list. The cost of repair will be estimated based on what was found in the initial evaluation.</p>
<h3>Price</h3>
<div class="note-callout">Not applicable to pre-assembled printers within warranty.</div>
<p><strong>You will not be charged anything else on top of the estimated cost of the repair.</strong> This estimate may only change with an additional request from your side (modification/upgrade of the printer) and must be approved by both the customer and the service technician.</p>
<p>The total cost of the repair will be:<br />
Shipping both ways + Technician's time + Parts to be changed.</p>
<ul>
<li><strong>The shipping cost is based on your address.</strong> If you want to know the price, go to our e-shop and add the pre-assembled version of your printer to the cart along with your address. This will show the shipping one way, and the total shipping to be paid will be twice that amount. If you want us to use a specific carrier or use your own carrier, this must be specified when requesting the repair. When using your own carrier, any damage during shipping will be your responsibility.</li>
<li><strong>The technician's time is charged by the hour.</strong> Once the scope of the repair is known, the technician will provide you with a time estimate including the expected price. This value can be charged in any of the currencies available the <a href="https://shop.prusa3d.com/">e-shop</a> (CZK, USD, EUR, PLN, and GBP).</li>
<li><strong>The parts have our retail prices</strong> and will be listed in the price estimate.</li>
</ul>
<p>A "reserve amount" will be added to the price estimate. This amount is calculated based on the total repair cost. It will cover the technician's time and parts in case of undisclosed issues or in case the printer has any third-party modifications. If nothing is found, this value is not added to the final amount.</p>
<p><strong>The repair will only commence after the costs are accepted.</strong> In case you do not accept the repair costs, the printer will be shipped back as-is. In this case, the shipping fees of the return will be charged. After payment, the printer is shipped back without being repaired.</p>
<h3>Repair</h3>
<p>The printer will be repaired by our service team, and a sequence of prints will be made to test all the printer features. This includes any specific G-codes that you have issues with (if these are added to the SD card and <strong>mentioned in the service list</strong>), plus test prints of the printer's main features.</p>
<div class="note-callout">If you want defect/replaced parts shipped back to you with the repaired printer, be sure to specify this on the <a href="https://www.prusa3d.com/downloads/others/PrusaServiceList_EN.pdf">Service list</a>. However, this can impact the shipping cost.</div>
<p>After the printer is received, <strong>the repair can take up to 30 days (according to EU law)</strong>. However, this is only the worst-case scenario and we're usually able to process the standard repair requests in a shorter time. You can request a time estimate after the initial evaluation.</p>
<p>After the repair, the payment is made. The printer will be shipped back to you, along with the test prints and a final repair protocol detailing what was repaired or changed<em>.</em></p>
<h3>Repair warranty</h3>
<p><strong>The specific part of the printer that is repaired has three months warranty</strong> (repair contract). If the reported issue(s) of the repaired printer is still present upon return, or there are flaws due to poor workmanship or negligence by our service technicians, the printer can be returned for service again free of charge <strong>within these three months.</strong></p>
<p>However, the<strong>&nbsp;Repair Contract warranty is unrelated to the printer's general warranty.</strong> Furthermore, if another/new issue appears, unrelated to the repaired part, it is not covered under this three-month repair warranty. A new estimated cost of the repair will have to be prepared and confirmed.</p>

E-shop order creation

<h3>When will I receive an invoice? </h3>
<p>For orders with <strong>wire transfer</strong> payment method, our system generates a proforma invoice within a few minutes from order creation. For all orders with any payment method, as soon as your payment is received and paired with your order, a deposit payment confirmation is generated, and the final invoice is generated once your order is shipped out. </p>
<div class="tip-callout">We automatically send the generated documents to the email address associated with your order. </div>
<h3>How can I edit the delivery and the billing addresses in my order invoice? </h3>
<p>The delivery address and the billing address associated with your order can be modified using your order details page, as long as the order status is <strong>New</strong>. If your order status is different, it is not possible to further modify your order.</p>
<h3>Can I add or remove items to my order? </h3>
<p>Apart from a few exceptions, it is possible to add or remove items to your order using your order details page, as long as the order status is <strong>New</strong>.</p>
<p>If your order was already paid at the time of adding to it, our system will prompt you to pay the surcharge; if your order was already paid at the time of removing an item from it, our system will automatically generate a refund request for the price difference. </p>
<div class="warning-callout">If your order status is different, it is not possible to further modify your order.</div>
<h3>Why does the preparation time estimation change often? </h3>
<p>Although we are doing our best to minimize any delays, the preparation time estimation visible on your order details page can change multiple times, as it is only a timeframe estimation that relies on the actual production. </p>
<h3>My order includes multiple items with different preparation times. When will the items be shipped?</h3>
<p>All items within an order will ship at the same time, when all the items are ready. It is not possible to split an order into multiple parts. </p>
<h3>When will I receive the order tracking number? </h3>
<p>The tracking number is generated and sent to the email address associated with your order as soon as your order is packed and ready for courier pick-up. </p>
<h3>The tracking shows that my order was not shipped. What should I do? </h3>
<p>If the tracking number was generated less than 2 business days ago, it is regular and it means that your order is waiting for the courier to collect it. In case the tracking number was generated for a longer time, please contact our <a href="http://help.prusa3d.com/article/customer-support_2287">Customer Support</a>.</p>
<h3>The carrier contacted me asking for payment of duty fees. Should I cover it?</h3>
<p>For packages bound outside of the European Union, the VAT is not charged. However, you may need to pay import taxes, customs, or other taxes and fees once the package reaches the border of your country, depending on the policy of your local customs office. <strong>The customs clearance process has to be done on the customer's side, with the help of the customs broker they get from their carrier</strong> (<a href="https://en.wikipedia.org/wiki/Incoterms#DAP_–_Delivered_At_Place_(named_place_of_destination)" target="_blank" rel="noopener"><strong>DAP incoterms</strong></a>). </p>
<div class="note-callout">For more details, please review our <a href="http://help.prusa3d.com/article/vat-value-added-tax-customs-fees_1505">VAT &amp; Customs fees article</a>.</div>

<p>Our financial department will send you the refund within a maximum of 14 business days from the order cancelation. </p>
<h3>I canceled my order, but I changed my mind. Can I reinstate my order? </h3>
