2.2. Using and customizing PrusaSlicer

PrusaSlicer is Prusa’s highly modified fork of Slic3r, one of the early open source slicer offerings. Prusa has done extensive modification of PrusaSlicer, including a complete port from PERL to C++. At this point, there is little likelihood that PrusaSlicer and Slic3r can ever be merged back together. This rapid pace of development makes keeping documentation up to date a challenge. You are likely to find that screen details and features shown on these pages are changed in the latest versions of PrusaSlicer. In most cases, basic features should still function as described here.

Note

PrusaSlicer is under ongoing and heavy development. These pages are “mostly correct” as of version 2.3.3. A number of significant features have been added or changes with the release of PrusaSlicer 2.4alpha.

Note

These notes are based on my experiences with the Prusa i3 Mk3 and Artillery/Evnovo Sidewinder X1 printers. If you are using a different printer, please verify the hardware details are similar.

These notes are intended to fill the gap between Prusa’s documentation and the latest PrusaSlicer release.
