Slic3r

The Slic3r project was born in 2011 within the RepRap community as an effort to provide the growing 3D printing technology with an open and flexible toolchain . The code and the algorithms are not based on any other previous work. Readability and maintainability of the code are among the design goals. Slic3r, being a true non-profit community project , allowed the people to experiment with several original new features that have become common thereafter such as multiple extruders, brim, microlayering, bridge detection, command line slicing, variable layer heights, sequential printing (one object at time), honeycomb infill, mesh cutting, object splitting into parts, AMF support , avoid crossing perimeters, distinct extrusion widths, modifiers, and much more. All of these features were first introduced in Slic3r and are now part of the commercial software out there. G-code generation for FFF/FDM printers; conversion between STL, OBJ, AMF 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 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.

We have automated builds for Windows (64-bit) and OSX ( = 10.7). Get a fresh build now and stay up-to-date with the development! Slic3r is mainly a toolpath generator for 3D printers: it reads 3D models (STL, OBJ, AMF, 3MF) and it converts them into G-code instructions for 3D printers. But it does much more than that, see the features list below. Slic3r was born in 2011 within the RepRap community and thanks to its high configurability became the swiss-army knife for 3D printing. It served as a platform for implementing several new (experimental) ideas that later became technology standards , such as multiple extruders, brim, variable-height layers, per-object settings, modifiers, post-processing scripts, G-code macros and more. Despite being based on volunteer efforts, Slic3r is still pushing the boundaries of 3D printing.
