Overview

PrusaSlicer is a free, open-source 3D slicing software developed by Prusa Research. Originally forked from Slic3r, it has evolved into a feature-rich tool packed with advanced capabilities like paint-on supports, variable layer height, and multi-material printing support. While optimized for Prusa printers, it includes profiles for a wide range of third-party machines and is praised for its cutting-edge features and robust performance.

✨ Key Features

  • Paint-on supports and support blockers
  • Variable layer height smoothing
  • Multi-material printing support
  • Organic (tree) supports
  • STEP file import
  • Built-in profiles for hundreds of printers and filaments
  • G-code viewer

🎯 Key Differentiators

  • Cutting-edge features often introduced before competitors (e.g., organic supports, variable layer height)
