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>

<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>

<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>
<p> </p>


Support material

<p dir="ltr">The main purpose of infill is to provide internal support for top layers, which would otherwise have to bridge over empty space. Infill also affects the speed of printing, structural strength, filament consumption, and even the look of the printed object.</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>Fill density</h3>
<p>Most models can be printed with 10-15% infill. If the top of the model closes gradually, it can be printed hollow (0% infill), though we generally do not recommend it. If you need the model to be heavier, want more compression resistance or higher stiffness, you can increase the infill. You'll rarely need infill higher than 30%. Finally, you can print the model with 100% infill and the infill pattern will be forced to rectilinear. Keep in mind that 100% infill can have a negative impact on the look of the printed object.</p>
<div class="tip-callout"><strong>Increasing model strength</strong><br />The strength of a model is mostly defined by the number of <strong>perimeters (not infill</strong>). If you want to have a stronger print, increase the number of perimeters. That said, infill does help with compression resistance.</div>
<h3>Fill pattern</h3>
<p>PrusaSlicer offers many infill patterns to choose from - check the dedicated <a href="http://help.prusa3d.com/article/infill-patterns_177130"><strong>Infill pattern documentation page</a></strong>.</p>
<h3>Length of the infill anchor</h3>
<p>The infill is usually <strong>connected to the perimeters</strong> with a so-called anchor, which is a <strong>short line</strong> of another (inner) perimeter that turns into an infill line. This makes the infill sturdier and is required by some materials (namely PETG) to stabilize the extrusion flow at the start of an infill line.</p>
<p>The length of the infill anchor value sets how many millimeters of this anchor will connect the infill and the perimeters. If you set this value to 0, the infill will be printed independently on the perimeters. Set a higher value to print the anchor that will continue as the infill itself.</p>
<p>If expressed as a percentage (15%) it will be calculated over the infill extrusion width.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/7a35a3b708029b4e_painted.jpeg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/7a35a3b708029b4e_painted-600x334.jpeg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/7a35a3b708029b4e_painted-800x445.jpeg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/7a35a3b708029b4e_painted-300x167.jpeg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/7a35a3b708029b4e_painted-768x427.jpeg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/7a35a3b708029b4e_painted-1536x854.jpeg 1536w" alt="" /></p>
<h3>Maximum length of the infill anchor</h3>
<p>This value sets the maximum length of the infill anchor connecting the infill with perimeters.</p>
<p>Set this parameter to 0 to disable anchoring completely.</p>
<h3>Top fill pattern</h3>
<p>You can pick a custom infill pattern that only affects the top visible layer, not adjacent solid layers below. </p>
<h3>Bottom fill pattern</h3>
<p>You can pick a custom infill pattern that only affects the bottom visible layer, not adjacent solid layers above.</p>
<h3>Combine infill every X layers</h3>
<p>Different layer heights will be used for infill and for perimeters in order to speed up the print without sacrificing the print quality.<br />Example: Combine infill every 3 layers, layer height 0.1 mm, infill will be printed at 0.3 mm layer height.</p>
<div class="note-callout">The maximum layer height is limited by your nozzle diameter. If you try to combine infill every 1+ layers with 0.4 mm nozzle and 0.3 mm layer height, no change will actually happen because you cannot print layers bigger than (about) 0.32mm (80% of nozzle diameter).</div>
<div><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/combine_every-01.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/combine_every-01-300x169.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/combine_every-01-600x337.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/combine_every-01-768x432.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/combine_every-01-800x450.png 800w" alt="" width="699" height="393" loading="lazy" /></div>
<div style="text-align: center;"><em>Infill (grey) printed at double the layer height of perimeters (orange)</em></div>
<p style="text-align: center;"> </p>
<h3>Solid Infill every X layers</h3>
<p>This feature allows you to force a solid layer after every given number of layers. This can be useful to increase the strength of the printed part, however other options, such as increasing the number of perimeters or infill percentage are preferred. Another application would be to create separate internal cells in order to increase thermal insulation.</p>
<p><strong>Set to 0 to disable.</strong></p>
<h3>Fill angle</h3>
<p>Default angle for infill orientation. Cross-hatching will be applied to some infill patterns.</p>
<div class="note-callout"><strong>Bridges</strong> will be printed using the best direction PrusaSlicer can detect, so this setting does not affect them.</div>
<h3>Solid infill threshold area</h3>
<p>Force solid infill for regions having a smaller area than the specified threshold.</p>
<p><strong>Set to 0 to disable.</strong></p>
<p style="text-align: center;"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/solid_infill_threshold.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/solid_infill_threshold-300x92.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/solid_infill_threshold-600x184.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/solid_infill_threshold-768x236.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/solid_infill_threshold-800x246.png 800w" alt="" /><em>Solid infill threshold 0 (left), 15 (middle), 100 (right)</em></p>


Infill

Original Prusa SL1 3D printer is based on the MSLA printing process. Unlike Original Prusa i3 machines, this printer uses a high-resolution LCD panel and a UV LED to cure thin layers of resin to achieve an unprecedented level of detail.
