About PrusaSlicer

PrusaSlicer converts 3D models into print instructions with variable layer height, organic supports, gyroid infill and multi-material painting — and it supports non-Prusa printers too.

PrusaSlicer is completely free and open source (AGPL-3.0) — no trials, no subscriptions, no locked features. Always download from the official website to avoid bundled malware.
