</div>

Download PrusaSlicer

Q: Is PrusaSlicer free? 
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>.
Q: Can I use it with other printers (not Original Prusa)? 
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.
Q: Where are user profiles stored? Select Help - Show Configuration Folder
Windows C:/Users/username/AppData/Roaming/PrusaSlicer Mac&nbsp;“HDD” ▸ ⁨Users⁩ ▸ ⁨username⁩ ▸ ⁨Library⁩ ▸ ⁨Application Support⁩ ▸ ⁨PrusaSlicer Linux ~/.config/PrusaSlicer 
If you're using an alpha or beta version, the folder name will be PrusaSlicer-alpha or PrusaSlicer-beta respectively
Q: Did an update erase all my custom print profiles? 
A: No, PrusaSlicer always creates a backup of all print profiles before an update. Check the snapshots folder. Windows&nbsp;C:Users/username/AppData/Roaming/PrusaSlicer/snapshots Mac “HDD” ▸ ⁨Users⁩ ▸ ⁨username⁩ ▸ ⁨Library⁩ ▸ ⁨Application Support⁩ ▸ ⁨PrusaSlicer⁩ ▸ snapshots Linux ~/.config/PrusaSlicer/snapshots 
Q: Does it have custom supports? 
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>.
Q: How to orient my model so that one of its faces is on the print bed? 
A: Check the Place on Face function.
Q: Can I schedule a pause or a color change in PrusaSlicer? 
A: Yes, click the plus icon on the slider in the Preview mode.&nbsp;
Q: What is the correct spelling: Plater or Platter? 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 Plater.
Q: Does it have tree supports for FDM? 
A: No, at least for the time being. We are looking into how to make them work with FDM.
Q: How accurate are the print time estimates? 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.
Q: How do I import a custom profile A: File - Import - Import config
Q: Why is there an extrusion hanging in the air over a MMU (multi-material) wipe tower? 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.
Q: Why is the jerk unit in mm/s, if the physical unit should be the rate of change in acceleration = mm/s^3? 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.
Q: PrusaSlicer won't start on Ubuntu 
A:&nbsp;This may be due to missing package <code class="codesample-inline">overlay-scrollbar-gtk2</code>, install it using the following command:
<pre><code class="codesample-inline">sudo apt-get install --reinstall overlay-scrollbar-gtk2</code></pre>
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? 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.
Q: Strange pattern on a flat surface 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.
Q: PrusaSlicer freezes or gets stuck after launch and is not responding (often when opened on 2nd monitor), what's wrong? 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. 
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>.
Q: How can I move a model up in the Z direction? 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.
<h4 dir="ltr">FAQ for other vendors:</h4>

FAQ - PrusaSlicer

<h3 dir="ltr">Model import</h3>
First, you have to import your model. You can either drag and drop it directly to the PrusaSlicer window, use the Add button in the top toolbar or choose File - Import.
Supported 3D formats are STL, STEP, 3MF, OBJ, and AMF.
<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" />
<h3 dir="ltr">Model orientation</h3>
It’s possible that your model may be oriented incorrectly after import. If that’s the case you can use to Rotate tool R 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.
Alternatively, you can use the Place on Face 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.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://lh3.googleusercontent.com/zs7JvVGbNSZNoP_bSWx9Ux5s-2Qdjl7aGG7_lnhTOBNDoFxBHh772qyUWSNHSLADfKSVbNSE7O0Jseg3CbyM2Jt91U3Zj7zqOJqSN7RrENnsBKY99YeHYLehPI1pGUqXwPxzTd-I" width="602" height="339" loading="lazy" />
 
<h3 dir="ltr">Selecting printer</h3>
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 chose to import multiple printer profiles, select the one you wish to use from the drop-down menu in the right panel.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/printer_select.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/printer_select-300x131.png 300w, https://help.prusa3d.com/wp-content/uploads/printer_select-600x262.png 600w" alt="" width="490" height="214" loading="lazy" />
<h3 dir="ltr">Selecting material</h3>
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.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/filament_selection.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/filament_selection-176x300.png 176w, https://help.prusa3d.com/wp-content/uploads/filament_selection-235x400.png 235w, https://help.prusa3d.com/wp-content/uploads/filament_selection-352x600.png 352w" alt="" width="269" height="458" loading="lazy" />
<h3 dir="ltr">Selecting a print profile/layer height</h3>
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.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/print_settings.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/print_settings-300x183.png 300w" alt="" width="268" height="164" loading="lazy" />
<h3 dir="ltr">Supports</h3>
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.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/supports.jpg" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/supports-300x92.jpg 300w, https://help.prusa3d.com/wp-content/uploads/supports-600x184.jpg 600w, https://help.prusa3d.com/wp-content/uploads/supports-768x235.jpg 768w, https://help.prusa3d.com/wp-content/uploads/supports-800x245.jpg 800w" alt="" />
A model that needs supports (left), a model with generated supports (right)
<h3 dir="ltr">Infill</h3>
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. The amount of infill can be adjusted in the right panel. Generally, values around 15% work well.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/infill.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/infill-300x204.png 300w, https://help.prusa3d.com/wp-content/uploads/infill-590x400.png 590w, https://help.prusa3d.com/wp-content/uploads/infill-768x521.png 768w, https://help.prusa3d.com/wp-content/uploads/infill-800x543.png 800w" alt="" />
<h3 dir="ltr">Brim</h3>
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.
<img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/wp-content/uploads/brim.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/brim-300x180.png 300w, https://help.prusa3d.com/wp-content/uploads/brim-600x359.png 600w, https://help.prusa3d.com/wp-content/uploads/brim-768x460.png 768w, https://help.prusa3d.com/wp-content/uploads/brim-800x479.png 800w" alt="" />
<h3 dir="ltr">Previewing G-code before print</h3>
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.
<h3 dir="ltr">Exporting the G-code</h3>
PrusaSlicer automatically detects if you insert an SD card, USB flash drive, or other removable media.
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.
If multiple SD cards or USB flash drives are detected, the file dialog is opened at the last visited removable media. Once a G-code is exported to a removable media, an Eject button is shown next to the Export G-code button, which will safely disconnect your device.

First print with PrusaSlicer

<h3>Welcome to PrusaSlicer documentation (PrusaSlicer manual)</h3>
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/">Slic3r</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.
PrusaSlicer is available for <a href="http://help.prusa3d.com/article/download-prusaslicer_2220">Windows, Mac and Linux</a>
<h3>History</h3>
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;Alessandro Ranellucci 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;
<img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://help.prusa3d.com/en/wp-content/uploads/jo_and_allesandro.png" sizes="100vw" srcset="https://help.prusa3d.com/wp-content/uploads/jo_and_allesandro-300x170.png 300w, https://help.prusa3d.com/wp-content/uploads/jo_and_allesandro-600x341.png 600w, https://help.prusa3d.com/wp-content/uploads/jo_and_allesandro-768x436.png 768w, https://help.prusa3d.com/wp-content/uploads/jo_and_allesandro-800x454.png 800w" alt="" width="421" height="239">Jo and Alessandro in 2012 (<a href="https://youtu.be/Tuxg2L7r1oI">video interview</a>)
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.
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;
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.
Of course, it’s still open-source and you’ll find everything on our <a href="https://github.com/prusa3d/PrusaSlicer">GitHub</a>. And we’re still proud that our slicer is based on the <a href="https://slic3r.org/">original project written by Alessandro Ranellucci</a>! Both projects now happily coexist and new features are frequently merged between one and another.
