PrusaSlicer
Open-source, feature-rich, and frequently updated.
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)
- Strong integration with the Prusa hardware ecosystem
- Excellent performance and stability
Unique Value: Provides access to the latest advancements in slicing technology for free, enabling users to produce higher quality prints with more control and less effort.
