Layers and perimeters

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.
<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>
PrusaSlicer can both detect areas that need supports and generate them in these places automatically.
You can also set supports manually using:
<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>
Supports can be turned on from the right panel or in the Print settings - Support material - Generate support material.
There are 3 different Support styles in PrusaSlicer
<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>
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.
<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, consider wearing protective glasses (this sounds stupid until you get hit in the eye for the first time).</div>
<h3 dir="ltr">Supports everywhere</h3>
Supports can grow from both the print bed and any model surface when necessary. 
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.
<h3 dir="ltr">Supports from build plate only</h3>
Creates only supports that have their base at the print bed.

Supports from build plate only (left), supports everywhere (right)
<h3 dir="ltr">For support enforcers only</h3>
Automatic support generation is enabled only for areas marked with a support enforcer. This option is essentially a shortcut that turns Print settings - Support material - Generate support material on, but Print settings - Support material - Auto-generated supports off.
<h3 dir="ltr">Supports on/off for individual models</h3>
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 right-clicking on a model in the 3D view and selecting Support material. Alternatively, you can right-click on the editing icon in the Object list.
A new window will appear in the right panel called Object settings to modify - Support material. 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.
<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" />
<h3 dir="ltr">Support enforcer/blocker</h3>
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 Overhang threshold setting nor selecting Supports on built plate only helped, you can adjust supports manually.
<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>
Right-click on a model and choose either a Support blocker or Support enforcer.
Simple mode - Enforcers/blockers are always box-shaped
Advanced mode - Box/Cylinder/Sphere/Slab shapes
Expert mode - Option to load external geometry as a blocker/enforcer
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.
<h3 dir="ltr">Support blocker</h3>
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.
<h3 dir="ltr">Support enforcers</h3>
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. 
It’s less common, but you can also use support enforcers with the automatic generation on.
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.
<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">Generate support material</h3>
Supports are disabled unless a model has an overwrite for this setting
<h3 dir="ltr">Auto-generated supports</h3>
When off, the overhang detection is off. Only support enforcers generate supports.
<h3 dir="ltr">Overhang threshold</h3>
The Overhang threshold value represents the most horizontal slope (measured from the horizontal plane) that you can print without support material (90=vertical).
Changing this value is a quick way to adjust the amount of generated supports.
The lower the value, the less support will be generated.

<h3 dir="ltr">Enforce support for the first</h3>
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.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/enforce_for_layers.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/enforce_for_layers-300x204.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/enforce_for_layers-587x400.jpg 587w, https://cdn.help.prusa3d.com/wp-content/uploads/enforce_for_layers-768x523.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/enforce_for_layers-800x545.jpg 800w" alt="" />Enforce support for the first 100 layers
<h3 dir="ltr">Raft layers</h3>
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.
<h3 dir="ltr">Raft contact Z distance</h3>
The vertical distance between the raft and the object. Ignored for soluble interfaces.
<h3>Raft expansion</h3>
Expansion of the raft in the XY plane for better stability.
<h3>Style</h3>
Style and shape of supports. The default Grid 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 Snug 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.
<img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2022/01/snug_vs_grid.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2022/01/snug_vs_grid-600x190.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/01/snug_vs_grid-800x253.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/01/snug_vs_grid-300x95.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/01/snug_vs_grid-768x243.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/01/snug_vs_grid-1536x485.jpg 1536w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/01/snug_vs_grid-2048x647.jpg 2048w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/01/snug_vs_grid.jpg 1600w" alt="" width="1847" height="584" loading="lazy" />
Grid supports (left), Snug supports (right)
<a href="https://help.prusa3d.com/article/organic-supports_480131">Organic supports</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.
<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">Top contact Z distance</h3>
The vertical distance between the object and the support material interface.
Setting this to 0 will prevent PrusaSlicer from using bridge flow and speed for the first object layer.
Values between 50-75% of the layer height seem to work well.
<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="" />
<h3 dir="ltr">Bottom contact Z distance</h3>
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).
<h3 dir="ltr">Pattern</h3>
Rectilinear - default, usually the easiest to remove
Rectilinear grid - sturdier and less prone to breaking during printing compared to rectilinear infill, harder to remove
Honeycomb - sturdy, somewhat difficult to remove
<h3 dir="ltr">With sheath around the support</h3>
Creates a single perimeter around the supports, which makes them sturdier, but more difficult to remove.
<h3 dir="ltr">Pattern spacing</h3>
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.
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.
<h3 dir="ltr">Pattern angle</h3>
Rotates infill pattern angle on the horizontal plane.
<h3 dir="ltr">Closing radius</h3>
For Snug supports only. Gaps smaller than the closing radius will be filled in.
<h3 dir="ltr">Top interface layers</h3>
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.
<h3 dir="ltr">Bottom interface layers</h3>
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).
<h3 dir="ltr">Interface pattern spacing</h3>
Spacing between interface lines. Set to 0 to get a solid interface.
<h3 dir="ltr">Interface loops</h3>
When enabled, the top layer of supports is covered with loops - continuous polylines.
<h3 dir="ltr">Support on build plate only</h3>
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.

Supports everywhere (left) vs Supports on build plate only (right)
<h3 dir="ltr">XY separation between an object and its support</h3>
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.
If expressed as a percentage (for example 150%) it will be calculated over the external perimeter width.
<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="" />
<h3 dir="ltr">Don’t support bridges</h3>
Prevents support material from being generated under bridged areas.
<h3 dir="ltr">Synchronize with object layers</h3>
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.
Synchronize with object layers can only be enabled with soluble supports (contact Z distance 0). 
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.

Manual changelog MK2.5S

The default nozzle diameter for most of today’s printers is 0.4 mm. If you decide to use a different diameter nozzle (you can read all about the benefits in <a href="https://blog.prusaprinters.org/everything-about-nozzles-with-a-different-diameter_8344/">our article</a>) and there isn't a built-in profile for it, you'll have to make one yourself.
Rather than creating a brand new profile, it's best to start with an existing profile and just modify it. 
The two main things that have to be adjusted are:
<ul>
<li>Nozzle diameter in Printers tab -&gt; Extruder 1</li>
<li>Extrusion width in Print settings tab -&gt; Advanced</li>
</ul>
That means you'll have to save not only a new printer profile but also new print profiles.
<div class="note-callout">Original Prusa printers in PrusaSlicer have built-in profiles for a variety of different nozzle sizes. Go to Configuration - Configuration Wizard - Prusa FFF and tick the boxes for profiles you wish to import, e.g. "0.25 mm nozzle"

</div>
<h3>Nozzle diameter in extruder settings</h3>
Go to Printers tab -&gt; Extruder 1 -&gt; Nozzle diameter and enter the exact diameter of your new nozzle and if it is high flow or not.
This value is used in PrusaSlicer mostly as a machine limit. For example, you can't print with a layer height bigger than your nozzle diameter. Your layer height should be 70-80% of your nozzle diameter at maximum, otherwise, the layer adhesion will be significantly compromised. PrusaSlicer also notes the nozzle diameter in the exported G-code as a comment. This is very helpful because the printer can warn you if you accidentally try to print a G-code generated for a different nozzle size.
However, on its own, changing this value won't make PrusaSlicer generate thicker extrusion lines.

<h3>Extrusion width in print settings</h3>
Setting up the extrusion width is the most important thing when creating a profile for a new nozzle.
Go to Print settings tab -&gt; Advanced.
You'll see a list of different extrusion width settings which can be added as a measurement in millimeters or as a percentage. The Support Material extrusion width is only enabled if the option "Generate Support materials" is selected in Print settings tab -&gt; Support Material.
<ul>
<li>Enter the Default extrusion width manually (e.g. 0.45 mm)</li>
<li>If you enter 0 PrusaSlicer will derive the extrusion width from the nozzle diameter
<ul>
<li>1.125 × nozzle diameter will be used</li>
</ul>
</li>
<li>You can also enter a percentage (e.g. 120%)
<ul>
<li>the percentage is calculated from the layer height, not the nozzle diameter</li>
</ul>
</li>
</ul>
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2024/12/cc72de12afd130cd53828c3579032687.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="Creating profiles for different nozzles REVIEW" alt="" width="700" height="359" loading="lazy" />
<h4>Extrusion width tips</h4>
Generally, you want your extrusion width to be about 110% of your nozzle diameter.
You can increase the extrusion width of the first layer to make it stick better to the print bed (e.g. 120-140% of nozzle diameter) at the cost of lower resolution in the XY plane.
By setting the extrusion width lower than the nozzle diameter you can make supports weaker and easier to remove.
<h3>Printer nozzle diameter check on the MK3/S</h3>
If you set up a profile for custom nozzle size and you're using the Original Prusa i3 MK3/S/+, disable the nozzle diameter check G-code.
Go in the printer menu to Settings -&gt; HW setup -&gt; Checks - Nozzle. Change it to Warn to receive a warning that can be skipped, or change it to None for the printer to ignore the different nozzle diameters.
Alternatively, you can delete the line directly from the Gcode in Prusa Slicer. Note that this is only recommended for advanced users. Go to Printers tab -&gt; Custom G-code -&gt; Start G-code and delete the line that says <code class="codesample-inline">M862.1 P[nozzle_diameter] ; nozzle diameter check</code>

Creating profiles for different nozzles

PrusaSlicer supports custom print bed textures and models in both PNG and SVG formats.
You can assign a custom model or texture by selecting Printers tab -&gt; General -&gt; Bed shape -&gt; Set.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog-300x279.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog-430x400.png 430w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog-768x714.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog-645x600.png 645w" alt="" width="429" height="399" loading="lazy" />
If the texture size doesn't match the bed size, the texture will be stretched to perfectly fit the bed. It is not currently possible for the texture to have elements outside of the print area.
The full path to the selected files is stored in "bed_custom_texture" and "bed_custom_model" Print profile variables.
<h3>Exporting SVG textures from Adobe Illustrator</h3>
The <a href="https://github.com/memononen/nanosvg">Nano SVG</a> parser, which PrusaSlicer uses, does not support every feature of the SVG format. We suggest the following workflow to correctly export SVG texture from Adobe Illustrator:
<ol>
<li>Go in PrusaSlicer tp File - Export - Export As</li>
<li>Tick Use Artboards to make sure that the resulting size is correct</li>
<li>In the SVG Options dialog pick:
<ul>
<li>Styling - Inline style (Internal CSS is NOT supported)</li>
</ul>
</li>
<li>Confirm with OK</li>
</ol>
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export-300x254.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export-473x400.png 473w, https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export-768x649.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export-710x600.png 710w" alt="" width="413" height="349" loading="lazy" />
<h3>Performance</h3>
In order to prevent graphics issues due to the excessively detailed print bed textures not fitting into the GPU memory, we implemented the following strategies to cope with the low GPU memory issues:
<ul>
<li>We only rasterize the print bed texture to a high resolution of 8192x8192 pixels if the graphics card supports OpenGL 3.0 and newer, or if there is a Retina display connected to a Mac. Otherwise, a lower resolution 4096x4096 print bed texture is rasterized.</li>
<li>If the detected RAM size is less than 6GB the texture size is reduced by another 1/2 factor</li>
<li>The print bed texture is compressed with the <a href="https://github.com/Cyan4973/RygsDXTc">Real-Time DXT1/DXT5 C compression library</a>.</li>
</ul>
In addition to that, after the application start-up, a low-resolution print bed texture is loaded to the GPU first, while the higher resolutions are compressed and sent to the CPU progressively as they are ready.

Custom SVG and PNG bed textures

PrusaSlicer lets you choose a custom STL and use it as the bed model.
You can assign it by selecting Prints tab -&gt; General -&gt; Bed shape -&gt; Set and using Load... in the Model section.
If you save the Printer preset, this custom model will be loaded automatically every time you select it.
<img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/bed_model_slicer.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/bed_model_slicer-600x327.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_model_slicer-800x437.png 800w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_model_slicer-300x164.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_model_slicer-768x419.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_model_slicer-1536x838.png 1536w" alt="" />
<h3>The origin position</h3>
The position of the model origin (point with coordinates x:0, y:0, z:0) needs to be in the middle of the print bed area. If you load a custom model and it appears misaligned, the origin is not set properly.
To edit the origin position, you can use most 3D programs, such as Blender. Place the 3D cursor in the desired origin position, for example, by selecting two vertices in the opposite corner and using (F3) Snap cursor to selected. Then right-click the model and pick Set Origin - Origin to 3D Cursor.
Then move the cursor back to world origin (F3) Snap Cursor to World Origin. And lastly, pick (F3) Snap Selection to Cursor with the print bed model selected.
You can now export the STL (File-Export-STL-Tick "Selection only").
<img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/custom_bed_blender.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/custom_bed_blender-600x325.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/custom_bed_blender-800x434.png 800w, https://cdn.help.prusa3d.com/wp-content/uploads/custom_bed_blender-300x163.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/custom_bed_blender-768x416.png 768w" alt="" />A custom bed model opened in Blender, note the position of the model origin in the middle of the print bed. Also, note the unnecessarily high polygon count
<h3>Polygon count</h3>
Try to keep the polygon count as low as possible. The print bed model is visible almost at all times and having a high polygon count will add unnecessary load to your device.
An example size of a small model:
50 kB, 1500 vertices, 3500 faces
