About PrusaSlicer
PrusaSlicer takes your 3D models, generates printing instructions and sends them to your 3D printer. It supports both FDM and mSLA printers, and although it is developed by Prusa Research it also supports machines from a wide variety of manufacturers.
It is made for anyone who wants precise control over how a model is printed, from settings that affect the whole print down to single-layer adjustments. PrusaSlicer is originally based on Slic3r by Alessandro Ranellucci and the RepRap community.
Highlights
- Printing parameters from whole-print settings down to single-layer adjustments
- Paint, cut and arrange objects directly in the app
- Multiple projects open at once, each with multiple beds that can have different settings
- Multi-material printing support
- Advanced 3D preview of the generated print instructions
- Several ways to send prints to the printer, plus integration with PrusaConnect and Printables
