auto-repair of non-manifold meshes (and ability to re-export them).conversion between STL, OBJ, AMF, 3MF and POV formats.G-code generation for FFF/FDM printers.(Most of these are also available in the command line interface.) See the project homepage at for more information. Embeddable: a complete and powerful command line interface allows Slic3r to be used from the shell or integrated with server-side applications.Modular: the core of Slic3r is libslic3r, a C++ library that provides a granular API and reusable components.Robust: the codebase includes more than 1,000 unit and regression tests, collected in 6 years of development.Join our collaborative effort and help improve it! Community-driven: new features or issues are discussed in the GitHub repository.While novice users often need just few options, Slic3r is mostly used by advanced users. Advanced: many configuration options allow for fine-tuning and full control.Compatible: it supports all the known G-code dialects (Marlin, Repetier, Mach3, LinuxCNC, Machinekit, Smoothie, Makerware, Sailfish).We want to keep 3D printing open and free.

Open: it is totally open source and it's independent from any commercial company or printer manufacturer.Despite being based on volunteer efforts, Slic3r is still pushing the boundaries of 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.

Slic3r was born in 2011 within the RepRap community and thanks to its high configurability became the swiss-army knife for 3D printing. But it does much more than that, see the features list below. 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. The MacOS X build server is kindly sponsored by: So, what's this Slic3r? Get a fresh build now and stay up-to-date with the development! We have automated builds for Windows (64-bit) and OSX (>= 10.7).
