Slic3r is mainly a toolpath generator for 3D printers that can read 3D models (STL, OBJ, AMF, 3MF) and convert them into G-code instructions for 3D printers.

Slic3r is mainly a toolpath generator for 3D printers that can read 3D models (STL, OBJ, AMF, 3MF) and convert them into G-code instructions for 3D printers.

Features:

G-code generation for FFF/FDM printers;
conversion between STL, OBJ, AMF, 3MF, and POV formats;
auto-repair of non-manifold meshes (and ability to re-export them);
SVG export of slices;
built-in USB/serial host controller, supporting multiple simultaneous printers each one with a spool queue;
OctoPrint integration (send to a printer)
built-in projector and host for DLP printers
tool for cutting meshes in multiple solid parts with visual preview (also in batch using a grid)
tool for extruding 2.5D TIN meshes
