Free open-source slicer for FDM, SLA, and SLS printing
PrusaSlicer, from Prusa Research, supports FDM, SLA, and SLS printing workflows in one free application, with profiles for Prusa printers and many third-party machines. It's known for strong support generation and an active community that keeps contributing printer profiles, which matters a lot given how fragmented 3D printer hardware still is.
