<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">Layer height</h3>
<p dir="ltr">Height of the individual slices/thickness of each layer. Layer height is the main factor affecting both:</p>
<ul>
<li dir="ltr" role="presentation">print time</li>
<li dir="ltr" role="presentation">vertical resolution</li>
</ul>
<p dir="ltr">By choosing <strong>taller layer heights</strong> you can significantly <strong>shorten the print time</strong> at the cost of more visible layers. On the other hand, choosing <strong>a small layer height</strong> (e.g. 0.10 mm) will result in <strong>extra detail</strong> at the cost of longer print times.</p>
<p dir="ltr">Generally, we do not suggest going lower than 0.10 mm as the improvement in print quality with 0.07 or 0.05 mm layers is relatively minor with significantly longer print times.</p>
<p dir="ltr">Keep in mind, that layer height changes only the <strong>vertical </strong>resolution. For example, an embossed text parallel with the print bed will look the same regardless of the layer height. If you’re looking for increased resolution in the <strong>XY plane</strong>, <a href="https://blog.prusaprinters.org/everything-about-nozzles-with-a-different-diameter_8344/">check nozzles with a different diameter</a>.</p>
<p dir="ltr">The layer height should be below 80% of the nozzle diameter (e.g. the maximum layer height with a 0.4 mm nozzle is about 0.32 mm). The layer height cannot be higher than the nozzle diameter, PrusaSlicer will display an error message if you try to input such a value.</p>
<p dir="ltr">You can also consider using the <a href="http://help.prusa3d.com/article/variable-layer-height-function_1750">Variable layer height function</a>.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/layer_height.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/layer_height-300x118.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/layer_height-600x237.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/layer_height-768x303.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/layer_height-800x316.jpg 800w" alt="" /></p>
<h3 dir="ltr">First layer height</h3>
<p dir="ltr">When printing with low layer heights you might still want to print a thicker first layer to increase adhesion to the print bed. <strong>Original Prusa print profiles always use 0.20 mm as the first layer height.</strong></p>
<p dir="ltr">You can express this as an absolute value (e.g. 0.20 mm) or a percentage of the default layer height (e.g. 150%).</p>
<p>Changing the first layer height will most likely require adjusting the <strong>calibration of the first layer</strong> on your printer.</p>
<h3 dir="ltr">Perimeters</h3>
<p dir="ltr">Defines the minimum number of outlines that form the wall of a model. Original Prusa profiles always use a minimum of two perimeters.</p>
<p>The strength of a model is mostly defined by the number of perimeters (not the infill). If you want a stronger print, increase the number of perimeters.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/perimeters.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/perimeters-300x81.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/perimeters-600x162.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/perimeters-768x207.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/perimeters-800x216.jpg 800w" alt="" /></p>
<h3 dir="ltr">Spiral vase</h3>
<p dir="ltr">Creates a continuous single outline container, gradually increasing the Z height.</p>
<p dir="ltr">When printing anything with a single-perimeter wall, there is always a small flaw where the printer advances to the next layer. This spot, where the printer stops and finishes the perimeter, raises the Z height by the layer height and starts a new perimeter, creates an unsightly ‘scar’ running up the side of the model. This scar is also a weak point of the print.</p>
<p dir="ltr">the spiral vase does not have any such point where the layer changes, except the first N bottom solid layers. Instead, the height is increasing gradually all the time, until the top of the print is reached.</p>
<p dir="ltr">When the vase mode is activated, PrusaSlicer automatically sets related settings accordingly:</p>
<ul>
<li dir="ltr" role="presentation">one perimeter</li>
<li dir="ltr" role="presentation">0% infill</li>
<li dir="ltr" role="presentation">disabled top solid layers</li>
<li dir="ltr" role="presentation">disabled supports</li>
<li dir="ltr" role="presentation">disabled "ensure vertical shell thickness"</li>
</ul>
<div class="note-callout">Keep in mind that simply changing these settings and not enabling the vase mode is not the same as true vase mode, as the object won’t be printed continuously.</div>
<p dir="ltr">You can still adjust the number of <strong>bottom solid layers</strong>. Furthermore, you can adjust the <strong>External perimeters Extrusion width</strong> in the <strong>Advanced</strong> menu to get a thicker/stronger/watertight vase (e.g. from 0.45 to 0.6).</p>
<p dir="ltr">The model should be defined as a solid. Otherwise, PrusaSlicer will try (and fail) to create both inside and outside surfaces, so model the outside dimensions only.</p>
<p dir="ltr"><strong>Only one object at a time can be printed in the vase mode</strong>. If you had multiple objects on the print bed, it would be impossible to print them continuously. You can get around this limitation by enabling Sequential printing.</p>
<h3 dir="ltr">Recommended thin wall thickness</h3>
<p dir="ltr">For a selected number of perimeters and layer height, PrusaSlicer calculates the <strong>optimal thin wall thickness</strong>. If you go back to your CAD drawing and change the wall thickness to this exact value, you will eliminate unnecessary perimeter overlap and your print will have a perfect wall surface finish.</p>
<p dir="ltr">Normally you get recommendations for an even number of perimeters (2,4,6…). If you enable Detect thin walls, you will also get a recommendation for an odd number of perimeters (1,3…).</p>
<p dir="ltr">You may think, that when the extrusion width for a perimeter is 0.45 mm, two perimeters will be 0.90 mm wide (2x0,45). However, if you look at the recommendation for a 0.2 mm layer height, you will find that this is not true and the suggested value is 0.86 mm.</p>
<p dir="ltr">In order to understand how this number is calculated, we need to take a look at the perimeter cross-section. PrusaSlicer assumes that the cross-section of an extrusion is a rectangle with semicircular ends. Note that the extrusion width includes the two semicircular ends.</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/extrusion_approx-01-01-1.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/extrusion_approx-01-01-1-300x169.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/extrusion_approx-01-01-1-600x337.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/extrusion_approx-01-01-1-768x432.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/extrusion_approx-01-01-1-800x450.png 800w" alt="" /></p>

<p dir="ltr">Now let’s add a second extrusion/perimeter. If we suppose no overlap (tangent paths), there would be empty space (yellow). In order to fill the empty space and bond the perimeters together, PrusaSlicer slightly overlaps the perimeters. This is essentially why you can’t just multiply the number of perimeters by the width of a single perimeter to get the ideal wall thickness.</p>

<div class="note-callout">Note that the layer height (h) is used in the calculation and the implication this has - if you change the layer height, your ideal wall thickness will change as well!</div>
<p dir="ltr">For more information, check the <a href="https://manual.slic3r.org/advanced/flow-math">Slic3r Flow math page</a> (parts of this text are sourced from the same page).</p>
<h3 dir="ltr">Solid layers - top/bottom</h3>
<p dir="ltr">The bottom and top parts of models are usually filled with solid layers (100% infill).</p>
<p dir="ltr">You can set <strong>how many top and bottom layers</strong> you wish to print. You can also set a <span style="font-weight: 400;"><strong>minimum wall thickness</strong>, which is especially useful when using the variable layer height function. The tooltip below these settings will update with every change, giving you a better idea of the resulting top/bottom wall thickness.</span></p>
<p dir="ltr">Setting the top or bottom solid layers to 0 overrides the minimum wall thickness. So you don't have to set the minimum wall thickness to 0 as well to get top or bottom layers.</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/2024/08/41556b3e1891b8d0ae47c43fb032cb68.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="Layers and Perimeters REVIEW" alt="" width="600" height="128" loading="lazy" /></p>
<p dir="ltr">The top solid infill is essentially bridging over the infill pattern. Because of that, you’ll almost always see some sag in the first few solid infill lines. The lower the infill, the longer the bridging distance, and as a result the bigger the sag. This can be counteracted by simply increasing the number of solid layers - we suggest at least 3 top layers. You can further reduce this behavior with a modifier mesh, which increases the infill for the last few layers before the solid infill.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/top_layers-1.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/top_layers-1-300x99.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/top_layers-1-600x198.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/top_layers-1-768x254.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/top_layers-1-800x264.jpg 800w" alt="" /></p>
<p dir="ltr" style="text-align: center;"><em>From left to right, 1, 2, 3, and 5 top layers, printed at 0.1 mm layer height.</em></p>
<p dir="ltr">Note that when printing at low layer heights, you will need more solid layers to achieve the same top/bottom wall thickness (e.g. with 0.3 mm layer height use 3 top layers, with 0.1 mm layer height use 9 top layers).</p>
<p dir="ltr">The default solid infill pattern is rectilinear, however, there are several other patterns to choose from.</p>
<h3 dir="ltr">Extra perimeters if needed</h3>
<p>A legacy option that as far as we know, doesn't do anything anymore. Let us know if you find a case where this changes anything.</p>
<h3 dir="ltr">Ensure vertical shell thickness</h3>
<p>This option was removed in PrusaSlicer 2.6. The new algorithm is much smarter than the previous implementations and is automatically applied where needed.</p>
<p dir="ltr">This function solves one of the biggest issues of older slicers, holes between the perimeters on a slanted surface. This was typical when printing busts and other organic-looking models. Such objects typically had a few holes on top of the head. With this function enabled, PrusaSlicer ensures it lays down the needed (internal) supports for perimeters in an upcoming layer.</p>

<h3 dir="ltr">Avoid crossing perimeters</h3>
<p>Avoid crossing perimeters is an algorithm to minimize crossings of external perimeters during travel moves, which reduces stringing (especially with Bowden extruders) and improves overall print quality. </p>
<p dir="ltr">Enabling this feature slows down the G-code generation and increases print time somewhat (time increase varies between models).</p>
<p dir="ltr">This feature was significantly improved in PrusaSlicer 2.3. The new algorithm tries to route a travel path inside object islands with the shortest path while avoiding holes and concavities, while it takes the shortest path when traveling between islands.</p>
<p dir="ltr">If the detour is longer than the <strong>Max detour length</strong>, avoid crossing perimeters will not be applied for this travel move. You can use absolute values in millimeters, a percentage of the travel move, or set it to 0 to disable Max detour length check.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/avoid_crossing2.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/avoid_crossing2-600x286.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/avoid_crossing2-800x382.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/avoid_crossing2-300x143.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/avoid_crossing2-768x366.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/avoid_crossing2-1536x733.jpg 1536w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/avoid_crossing2-2048x977.jpg 2048w" alt="" width="1841" height="879" loading="lazy" /></p>
<h3 dir="ltr">Detect thin walls</h3>
<p dir="ltr">By default, every wall consists of outside and inside perimeters (a minimum of two perimeters for thin walls). If there is enough space, an infill pattern fills the void between these inside/outside perimeters. </p>
<p>Enabling <strong>Detect thin walls</strong> lets PrusaSlicer generate a single perimeter that works as both an inside &amp; outside shell. This will help to capture tiny details. However, walls thinner than a single perimeter extrusion width will likely still be ignored.</p>
<p>This feature is automatically disabled if the <strong>Arachne perimeter generator</strong> is active, as it already automatically adjusts for thin walls.</p>
<h3 dir="ltr">Thick bridges</h3>
<p>For historical reasons, PrusaSlicer used to print bridges with extremely thick lines. This makes bridging very reliable and lets you bridge longer distances, but they didn’t look good. The new default behavior uses your current layer height for bridging, making bridging reliable for shorter distances but looking significantly better. This is the strategy that most modern slicers use. You can switch to the old behavior by enabling the <strong>Thick Bridges</strong> option. Since the first solid layer above supports uses the bridging settings, <strong>this change also has a big impact on how supported overhangs look</strong>.</p>

<p style="text-align: center;"><em> Left: Thick bridges enabled, Right: Thick bridges disabled</em></p>
<h3 dir="ltr">Detect bridging perimeters</h3>
<p>Enables <strong>bridging flow</strong> for overhangs and turns on the fan. </p>
<h3>Seam position</h3>
<p>Determines the start point of each perimeter loop, and thus the position of the potentially visible <strong>vertical seam</strong> on the side of the object. Unless you're printing in the Spiral vase mode.</p>
<p>The seam looks like a tiny zit on the model surface. PrusaSlicer can attempt to hide the seam into model edges (using the “<strong>Nearest</strong>” setting) or on the rear side (“<strong>Rear</strong>”), spread them randomly on the surface (“<strong>Random</strong>”), or arrange them into lines (“<strong>Aligned</strong>”).</p>
<p>You'll find more information and pictures in the <a href="http://help.prusa3d.com/article/seam-position_151069">Seam position</a> article.</p>
<h3>Staggered inner seams</h3>
<p>This feature causes the inner seams to be shifted backward based on their depth, forming a zigzag pattern. This creates a stronger part by avoiding that the seams align.</p>
<h3>External perimeters first</h3>
<p>Perimeters will be printed from the outermost to the innermost ones instead of in the inverse order.</p>
<p>This parameter may help with <strong>dimensional accuracy</strong> since the outer perimeter is laid down first and any extra filament extruded when printing following perimeters is pressed back away from the outer wall. On the other hand, the surface may be slightly less smooth.</p>
<h3>Fill gaps</h3>
<p>Enables filling of gaps between individual perimeters and between the innermost perimeter and infill.</p>
<h3>Perimeter generator</h3>
<p>Allow you to switch between the Arachne (default) and the Classic perimeter generator. The Arachne perimeter generator automatically adjusts the extrusion width of perimeters as needed. For most prints the Arachne perimeter generator is superior, but for some functional prints where the accuracy of concave corners is important, the classic perimeter generator may be better.</p>


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>

<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>

<h3>Raft expansion</h3>

<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><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.

<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>
<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>

Manual changelog

<h3>Welcome to PrusaSlicer documentation (PrusaSlicer manual)</h3>
<p>PrusaSlicer (formerly known as Slic3r Prusa Edition or Slic3r PE) is our own in-house developed slicer software based on the open-source project <a href="https://slic3r.org/"><strong>Slic3r</strong></a>. PrusaSlicer is an open-source, feature-rich, frequently updated tool that contains everything you need to export the perfect print files for (not only) your Original Prusa 3D printer.</p>
<p>PrusaSlicer is available for <a href="http://help.prusa3d.com/article/download-prusaslicer_2220">Windows, Mac and Linux</a></p>
<h3>History</h3>
<p>The Slic3r project was born in 2011 within the RepRap community as an effort to provide the growing 3D printing technology under the leadership of&nbsp;<strong>Alessandro Ranellucci</strong> an open-source slicer. Slic3r spread among users quickly. When Josef Prusa was looking for a leading slicing software for Original Prusa printers the choice fell on Slic3r. It was (and still is) an open-source and very powerful software.&nbsp;</p>
<p style="text-align: center;"><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/en/wp-content/uploads/jo_and_allesandro.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/jo_and_allesandro-300x170.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/jo_and_allesandro-600x341.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/jo_and_allesandro-768x436.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/jo_and_allesandro-800x454.png 800w" alt="" width="421" height="239"><em>Jo and Alessandro in 2012 (<a href="https://youtu.be/Tuxg2L7r1oI">video interview</a>)</em></p>
<p>However, as Prusa Research was growing (very, very, very fast), we needed to be more flexible with the slicing software development. We needed to make changes to the software, and the changes had to be done asap. We also needed to add more features. At this point the co-operation with the detached original Slic3r team was unsustainable. The bottom line is that we decided to establish a fork of the original Slic3r project.</p>
<p>Slic3r Prusa Edition was released in November 2016 – <a href="https://blog.prusaprinters.org/introducing-slic3r-prusa-edition_4650/">read more about the launch here</a>. A dedicated team of full-time Slic3r PE developers was established and new functions were being added rapidly. These changes culminated in May 2019, when we released a new version with a major UI overhaul under a new name - <a href="https://blog.prusaprinters.org/prusaslicer-2-release_30008/">PrusaSlicer 2.0</a>.&nbsp;</p>
<p>Why the name change? First of all, the old name was really confusing. Even in our own materials, we often didn’t include the “PE” suffix, and the community used Slic3r and Slic3r PE pretty much interchangeably. New users could mistakingly download Slic3r and wonder why it looks different from the screenshots in the 3D Printing Handbook and why it’s not configured for their Prusa printer. Speaking about the original Slic3r: with each update, Slic3r PE was moving further and further away from its original code. We’ve rewritten all of the Perl source code into C++ and especially with the 2.0 update, there were so many differences that it seemed appropriate to make the name more distinct.</p>
<p>Of course, it’s still open-source and you’ll find everything on our <a href="https://github.com/prusa3d/PrusaSlicer">GitHub</a>. <strong>And we’re still proud that our slicer is based on the <a href="https://slic3r.org/">original project written by Alessandro Ranellucci</a>!</strong> Both projects now happily coexist and new features are frequently merged between one and another.</p>


General info

<p dir="ltr">If you are using <a href="https://www.prusa3d.com/page/prusaslicer_424/">PrusaSlicer</a> for the first time to generate a gcode or bgcode for printing, you can follow the steps below.</p>
<p dir="ltr">Click on the links to get more information about the available features.</p>
<div class="note-callout">The images below might be from old PrusaSlicer versions, but the functionalities are the same even if the interface looks different.</div>
<h3 dir="ltr">Model import</h3>
<p dir="ltr">First, you have to import your model. You can either <strong>drag and drop</strong> it directly to the PrusaSlicer window, use the <strong>Add button</strong> in the top toolbar, or choose <strong>File - Import</strong>.</p>
<p dir="ltr">Supported 3D formats are STL, STEP, 3MF, OBJ, and AMF.</p>
<p dir="ltr"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://lh5.googleusercontent.com/YX3xyJG4ArooSiafY0RO5jOmiVN2lceTx3llzIaBIBDAWSMvhVSnqFVpY0Ci5_ZtncNRKYUZJAOhb98M0_hUE6wxJL8PhpQL362SE2g9Lizofu2SRoTuHA1rwj5IrjEBUorPvV6j" width="500" height="281" loading="lazy" /></p>
<h3 dir="ltr"><a href="http://help.prusa3d.com/article/object-orientation_1658">Model orientation</a></h3>
<p dir="ltr">Your model may be oriented incorrectly after import. If that’s the case you can use the <strong><a href="http://help.prusa3d.com/article/move-rotate-scale-tools_1914">Rotate tool</a></strong> <span class="key">R</span> to manually adjust to the object’s orientation. When you pick a rotation axis, you can use the short guidelines to rotate by 5-degree increments or the long guidelines, which snap to 45-degree increments.</p>
<p dir="ltr">Alternatively, you can use the <span class="tooltip" data-tooltip="place-on-face_124588">Place on Face</span> tool. When you select it, several white planes will appear on your model. Clicking on the white plane will align it with the virtual print bed.</p>

<h3 dir="ltr">Selecting printer</h3>
<p dir="ltr">If you only selected one printer and nozzle size in the <a href="http://help.prusa3d.com/article/configuration-wizard_1754">Configuration Wizard</a>, you already have the correct printer selected. If you choose to import multiple printer profiles, select the one you wish to use from the drop-down menu in the right panel.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/printer_select.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/printer_select-300x131.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/printer_select-600x262.png 600w" alt="" width="490" height="214" loading="lazy" /></p>
<h3 dir="ltr">Selecting material</h3>
<p dir="ltr">Different materials require different print temperatures, print speed, cooling, and a variety of other settings. Luckily, PrusaSlicer comes with presets for many different materials, so you just have to select one from the drop-down menu in the right panel.</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/filament_selection.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/filament_selection-176x300.png 176w, https://cdn.help.prusa3d.com/wp-content/uploads/filament_selection-235x400.png 235w, https://cdn.help.prusa3d.com/wp-content/uploads/filament_selection-352x600.png 352w" alt="" width="269" height="458" loading="lazy" /></p>
<h3 dir="ltr">Selecting a print profile/layer height</h3>
<p dir="ltr">By adjusting the height of the individual printed layers you can balance the print quality and the print time. PrusaSlicer has various print profiles to select from. To start we suggest using 0.15 or 0.2 mm layers as they offer very good print quality at reasonable print times.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/print_settings.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/print_settings-300x183.png 300w" alt="" width="268" height="164" loading="lazy" /></p>
<h3 dir="ltr"><a href="http://help.prusa3d.com/article/support-material_1698">Supports</a></h3>
<p dir="ltr">Because each layer rests on top of the previous one, it may be necessary to print a support structure underneath parts, that would otherwise be printed in mid-air. Additionally, it’s difficult for the printer to reproduce very steep overhangs. PrusaSlicer can detect where to place supports and generate them automatically. To turn supports on pick either Supports: Everywhere or Supports: On build plate only from the drop-down menu in the right panel.</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.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/supports-300x92.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/supports-600x184.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/supports-768x235.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/supports-800x245.jpg 800w" alt="" /></p>
<p dir="ltr">A model that needs supports (left), a model with generated supports (right)</p>
<h3 dir="ltr"><a href="http://help.prusa3d.com/article/infill_42">Infill</a></h3>
<p dir="ltr">Objects are typically not printed solid, but not hollow either. A sparse infill pattern is used to fill the inside of the model. The main purpose of the infill is to provide an internal support structure for top layers, as well as to improve the mechanical properties of the print. On the other hand, we usually want to get away with as little infill as possible to reduce both print times and material consumption.</p>
<p dir="ltr">The amount of infill can be adjusted in the right panel. Generally, values around 15% work well.</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/infill.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/infill-300x204.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/infill-590x400.png 590w, https://cdn.help.prusa3d.com/wp-content/uploads/infill-768x521.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/infill-800x543.png 800w" alt="" /></p>
<h3 dir="ltr"><a href="http://help.prusa3d.com/article/skirt-and-brim_133969">brim</a></h3>
<p dir="ltr">A brim is used to increase adhesion to the print bed and decrease the possibility of warping. This is done by printing extra outlines of the first layer and it’s especially useful when the footprint of the first layer is very small. You can turn it on with a checkbox in the right panel. When the print is finished, it’s usually very easy to remove the brim by hand.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/brim.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/brim-300x180.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/brim-600x359.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/brim-768x460.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/brim-800x479.png 800w" alt="" /></p>
<h3 dir="ltr">Previewing G-code before print</h3>
<p dir="ltr">It’s a good practice to always preview the G-code before printing it. When you click the "Slice now" button, you’ll be automatically switched to the preview mode. Alternatively, you can use the switch between 3D view and preview mode in the lower-left corner or press the TAB key. Using the slider on the right, you can adjust the preview and inspect individual layers. Check the overall shape of the model and make sure it matches the 3D object. Watch out for parts, that would start printing in mid-air, if you notice any, it’s necessary to turn on support generation. If everything looks alright, you can proceed and select Export G-code.</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/2024/11/fbec8929c929c3e67999bc3451bda447_painted.jpeg" sizes="(min-width: 1024px) 820px, 100vw" srcset="First print with PrusaSlicer REVIEW" alt="" width="500" height="240" loading="lazy" /></p>
<h3 dir="ltr">Exporting the G-code</h3>
<p>PrusaSlicer automatically detects if you insert an SD card, USB flash drive, or other removable media.</p>
<p>When detected, a new Export to SD/USB drive button will appear next to the Export G-code button (bottom right corner). Clicking it will open the file save dialog with the path initialized to the SD card or USB flash drive.</p>
<p>If multiple SD cards or USB flash drives are detected, the file dialog is opened at the last visited removable media.</p>
<p>Once a G-code is exported to a removable media, an Eject button is shown on the bottom right of the plater, which will safely disconnect your device.</p>

First print with PrusaSlicer

<p dir="ltr"><strong>Q: Is PrusaSlicer free?</strong><br />
A: Yes. It’s also open-source, so anyone can contribute to the development. Check our <a href="https://github.com/prusa3d/PrusaSlicer">GitHub</a>.</p>
<p dir="ltr"><strong>Q: Can I use it with other printers (not Original Prusa)?</strong><br />
A: Yes. The community has made profiles for printers from many manufacturers. Many of them are now built-in to PrusaSlicer, you can add them via the Configuration Wizard. For printers that are not yet included, you can check your printer’s Facebook group or a forum, download the profiles and import them manually.</p>
<p dir="ltr"><strong>Q: Where are user profiles stored?<br /></strong>Select <strong>Help - Show Configuration Folder</strong></p>
<p><strong>Windows</strong> <em>C:/Users/username/AppData/Roaming/PrusaSlicer<br /></em><strong>Mac</strong>&nbsp;“HDD” ▸ ⁨Users⁩ ▸ ⁨username⁩ ▸ ⁨Library⁩ ▸ ⁨Application Support⁩ ▸ ⁨PrusaSlicer<em><br /></em><strong>Linux</strong> ~/.config/PrusaSlicer<br />
If you're using an alpha or beta version, the folder name will be PrusaSlicer-alpha or PrusaSlicer-beta respectively</p>
<p dir="ltr"><strong>Q: Did an update erase all my custom print profiles?</strong><br />
A: <span style="color: #ba372a;"><strong>No</strong></span>, PrusaSlicer always creates a backup of all print profiles before an update. Check the <em>snapshots folder.<br /></em><strong>Windows&nbsp;</strong><em>C:Users/username/AppData/Roaming/PrusaSlicer/snapshots<br /></em><strong>Mac</strong> “HDD” ▸ ⁨Users⁩ ▸ ⁨username⁩ ▸ ⁨Library⁩ ▸ ⁨Application Support⁩ ▸ ⁨PrusaSlicer⁩ ▸ snapshots<em><br /></em><strong>Linux</strong> ~/.config/PrusaSlicer/snapshots<em><br /></em></p>
<p dir="ltr"><strong>Q: Does it have custom supports?</strong><br />
A: Yes. Check the <a href="http://help.prusa3d.com/article/paint-on-supports_168584">Paint-on supports</a> and <a href="http://help.prusa3d.com/article/support-material_1698">support blockers and enforcers</a>.</p>
<p dir="ltr"><strong>Q: How to orient my model so that one of its faces is on the print bed?</strong><br />
A: Check the <span class="tooltip" data-tooltip="place-on-face_124588">Place on Face</span> function.</p>
<p dir="ltr"><strong>Q: Can I schedule a pause or a color change in PrusaSlicer?</strong><br />
A: Yes, click the plus icon on the slider in the Preview mode.&nbsp;</p>
<p dir="ltr"><strong>Q: What is the correct spelling: Plater or Platter?<br /></strong>A: Feel free to discuss at <a href="https://github.com/prusa3d/PrusaSlicer/issues/2074">#2074</a> or <a href="https://github.com/prusa3d/PrusaSlicer/issues/1226">#1226</a>, we're keeping it as <em>Plater</em>.</p>
<p dir="ltr"><strong>Q: Does it have tree supports for FDM?</strong><br />
A: No, at least for the time being. We are looking into how to make them work with FDM.</p>
<p dir="ltr"><strong>Q: How accurate are the print time estimates?<br /></strong>A: Very accurate, often less than a minute difference on a print that takes 10+ hours. However, this is only true if you select the correct printer profile that matches your actual printer. The print time estimate takes into account acceleration, jerk and other settings that differ from machine to machine.</p>
<p dir="ltr"><strong>Q: How do I import a custom profile<br /></strong>A: File - Import - Import config</p>
<p dir="ltr"><strong>Q: Why is there an extrusion hanging in the air over a MMU (multi-material) wipe tower?<br /></strong>A: That is the final ramming before the filament is pulled from the nozzle and parked into the filament switcher. See <a href="https://github.com/prusa3d/PrusaSlicer/issues/1355">#1355</a> for further details.</p>
<p dir="ltr"><strong>Q: Why is the jerk unit in mm/s, if the physical unit should be the rate of change in acceleration = mm/s^3?<br /></strong>A: The <a href="https://github.com/gnea/grbl">GRBL</a> project overloaded the term "jerk" to define maximum instantaneous velocity change, which is easier to be implemented by 8bit controllers, and most of today's 3D printer firmware is based on the GRBL planner. See <a href="https://github.com/prusa3d/PrusaSlicer/issues/2339">#1355</a> for further details.</p>
<p><strong>Q: PrusaSlicer won't start on Ubuntu<br />
A:&nbsp;</strong>This may be due to missing package <code class="codesample-inline">overlay-scrollbar-gtk2</code>, install it using the following command:</p>
<pre><code class="codesample-inline">sudo apt-get install --reinstall overlay-scrollbar-gtk2</code></pre>
<p dir="ltr"><strong>Q: When exporting a G-code, the file save dialog shows <code class="codesample-inline">{print_time}</code>&nbsp;tag in the file name instead of the actual print time, why?<br /></strong>A: This happens if you click on the Export G-code button right after slicing and the G-code analysis is still running on the background. If you save the file, the tag will be properly replaced with the time estimate.</p>
<p><strong>Q: Strange pattern on a flat surface<br /></strong>A: A perfectly flat surface may not stay perfectly flat after being rotated in a 3D modeling software. If PrusaSlicer happens to slice across such a no more perfectly flat surface, weird one layer thick islands may show up. See <a href="https://github.com/prusa3d/PrusaSlicer/issues/2434">#2434</a> for further details.</p>
<p dir="ltr"><strong>Q: PrusaSlicer freezes or gets stuck after launch and is not responding (often when opened on 2nd monitor), what's wrong?<br /></strong>A1: This is likely caused by the Nahimic audio driver, which some notebook/pc manufacturers pre-install on their machines. You can solve the issue by stopping and disabling the Nahimic driver. You can learn more in this <a href="https://forum.prusaprinters.org/forum/prusaslicer/pursaslicer-2-0-0-not-responding/paged/2/#post-195065">forum thread</a> or on this <a href="https://github.com/prusa3d/PrusaSlicer/issues/2522">GitHub issue</a> page.<br />
A2: You may be running an app that integrates with other applications, such as the Blue Cielo "Application Integration". Such apps autoload at startup and inspect/change menu bars etc. If you discover such an app on your device, whitelist PrusaSlicer. More info on <a href="https://github.com/prusa3d/PrusaSlicer/issues/2939">this GitHub issue</a>.</p>
<p dir="ltr"><strong>Q: How can I move a model up in the Z direction?<br /></strong>A: Place your base object normally, then right click on it and 'add part', select the model that you want to place on top. More information is in <a href="https://help.prusa3d.com/en/article/how-to-lift-object-from-the-print-bed_245192?preview=true">this article</a>. As well as the explanation why this can't be done easier at the moment.</p>
<h4 dir="ltr">FAQ for other vendors:</h4>
<p><strong>Q: We would like to modify (possibly re-skin) PrusaSlicer and release it for our customers, is that ok?</strong><br />
A: Yes. However, you will have to release the full source code including all the changes that you've made. Please check the <a href="https://www.gnu.org/licenses/agpl-3.0.en.html"><em>GNU Affero General Public License, version 3</em></a>.</p>
<p><strong>Q: We would like to use PrusaSlicer to create a cloud slicing service<br /></strong>A: Feel free to do so, but just like when releasing a modified version, you will have to release the full source code including all the changes that you've made.
