Free and open-source
PrusaSlicer is based on Slic3r by Alessandro Ranellucci. Thanks to the strong community and a team of developers in Prusa Research we can continually add new features. Follow the development on our GitHub.
An open-source, feature-rich, frequently updated tool that contains everything you need to export the perfect print files for your 3D printer.
PrusaSlicer includes community profiles for 3rd party printers.
BUT only with Original Prusa printers you will get 180+ tested and auto-updated profiles for the most popular filaments and resins.

We've reworked the UI and exposed all the power features while making the UI clear and simple to use at the same time. It looks great on a small laptop screen as well as on a HiDPI multi-monitor setup.
Paint custom supports directly on the model, it's quick and easy. You can also use custom meshes as support blockers and enforcers. Everything is neatly saved in the project file, always customizable.
Testers and developers at Prusa Research are constantly working on presets for 250+ filaments and resins by the most popular manufacturers. You will get new profiles automatically through the auto-update function.
Coloring an object for multi-material printing requires just a handful of clicks with the smart fill and brushstroke tools! During slicing, the painted regions are cleverly extended inwards for the best material adhesion.
Import STEP files directly and skip converting CAD models into an STL. STEP is interoperable among most CAD programs including Fusion 360, FreeCAD, SolidWorks, Inventor, AutoCAD, CATIA, and many more.
You can prepare prints with color changes directly in PrusaSlicer. Just click on the slider in the print preview screen. A preview is displayed instantly so you’ll see exactly how your model will look with color-change.
Thanks to the help of our wonderful community, we're growing the collection of fine-tuned 3rd party printer profiles, including Creality, Voron, or Anycubic printers.
The legend in the preview shows a breakdown of the print time by feature. Change any of the settings and watch how the print time changes.
Send G-code directly to your printer with a single click of a button. We support Octoprint, Repetier Host, FlashAir SD cards and more! PrusaSlicer also works with advanced features of Octoprint like upload queue or Cancelobject plugin.
You can select the layer height for each part of the object separately. Our software takes care of smoothing so the final print looks best as it can and the printing time remains acceptable. Check out the video.
With the release of our Original Prusa SL1 resin 3D printer, we’ve added MSLA mode into PrusaSlicer. As far as we know, PrusaSlicer is the first high-quality open-source MSLA slicer available. PrusaSlicer also supports multi-material FFF printing with the Original Prusa MMU2S.
A lightweight application, which you can use to quickly preview G-codes from all popular slicers.
Its behavior is identical to the preview in PrusaSlicer (the same code is used), however, you can load an external G-code file.
We currently parse, and up to some level interpret, G-code from PrusaSlicer, Slic3r, Slic3r PE, CURA, ideaMaker, Simplify3D, Craftware and KISSSlicer. PrusaSlicer G-code Viewer is part of the PrusaSlicer installer package. Simply download the latest PrusaSlicer and the standalone G-code Viewer will install together with it automatically.
