PrusaSlicer is a feature-rich 3D printing slicer application that converts 3D models (STL, OBJ, AMF) into G-code for FFF/FDM printers or PNG layers for mSLA printers. Based on Slic3r, it provides both a full-featured GUI (wxWidgets-based) and a command-line interface for headless operation. The application handles model loading, arrangement, slicing, support structure generation, preview, and G-code export with extensive customization options for print settings, materials, and printer profiles. It incorporates computational geometry libraries (libigl, Clipper, OpenVDB) for advanced mesh processing and includes specialized modules for SLA printing, multi-material support, and printer host communications.
