Internally designed laminating software based on the open source project Slic3r


PrusaSlicer (formerly known as Slic3r Prusa Edition or Slic3r PE) is our own in-house developed slicer software based on the open-source project Slic3r. It's open-source and you can get it in our Drivers & Apps Package. PrusaSlicer is a feature-rich, frequently updated tool that contains everything you need to export the perfect print files for your Original Prusa 3D printer.

PrusaSlicer is available for Windows, Mac and Linux.


Originating from a forked version of Slic3r, PrusaSlicer has gained a lot of popularity for a number of reasons. Not only does it feature vast lists of tunable settings, but it also has some handy features not seen in the original.

With a reworked interface, native support for Prusa’s own printer lineup, and handy presets for a number of common materials, there are a large number of improvements over the original software. Some key features include customizable support structures, multi-material support, and smooth variable layer height functions.

PrusaSlicer can be used to slice models for both FDM and resin printers, and has various modes that allow you to edit settings based on your skill level, with Expert opening up a huge list of things to customize. Fear not though, even simple profiles can perform well in PrusaSlicer.

Having originated in Slic3r, PrusaSlicer maintains support for most of the original features, and even accepts Slic3r configuration bundles when importing profiles.
