Cura aims to be a end solution for personal 3D printing with RepRap based machines. It is tuned toward the Ultimaker, but can be used on any RepRap based design.


Netfabb is not available for Mac but there are plenty of alternatives that runs on macOS with similar functionality. The best Mac alternative is Cura, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 25 alternatives to Netfabb and 14 are available for Mac so hopefully you can find a suitable replacement.

Creality Print is a self-developed Fused deposition modeling slicing software produced by Creality. It’s a practical and easy-to-use tool that can help you remote control and monitor your 3D printer and help print directly from your computer.




F3D (pronounced /f?d/) is a fast and minimalist 3D viewer desktop application. It supports many file formats, from digital content to scientific datasets (including glTF, USD, STL, STEP, PLY, OBJ, FBX, Alembic), can show animations and support thumbnails and many rendering and...




STL-to-GCODE translator for RepRap printers
Here comes Slic3r! Its features are:


Software for controlling RepRap style 3D-printer like Mendel, Darwin or Prusa mendel. Works with most firmware types. It is optimized to work with Repetier-Firmware Other working firmware is Sprinter, Teacup, Marlin and all compatible firmwares.

This is the software that will drive your MakerBot Replicator, Thing-O-Matic, CupCake CNC, RepRap machine, or generic CNC machine. You can give it a GCode or STL file to process, and it takes it from there.

Prepare files for printing with ideaMaker, Raise3D’s powerful slicing software. The user friendly interface can prepare STL, OBJ and 3MF files within 2 clicks, while defined settings provide limitless customization for advanced users.





SuperSkein is a first-order model slicer that runs in Processing. It's pretty basic still, but since it's object oriented and in Processing (which could be quickly ported to C) it should be easy for the community to hack and improve.
fstl is cross-platform and open-source. Precompiled binaries are available for Windows and Mac, and the only dependancy is Qt if you want to build it yourself.


I have been using Kisslicer since 2014. It is easy to work with. The latest version which came out in late 2017 is even easier to work with and has many more control parameters for making your prints come out more successfully than before.
