Slicing software which takes a 3D model and converts it into a gcode toolpath. More about Slic3r. Calibration questions? This software can also be used for dual extruder printers.


Skeinforge is a collection of python scripts that is used to generate Gcode for the printers. Custom plugins can be added to Skeinforge to allow more functionality. To learn more see Installing Skeinforge Plugins. It is no longer being updated.

G-code senders


Pronterface is G-code sending tool used to communicate with the printer and send commands and toolpaths.

More details can be found here. A ready-to-use build can be found here.


Repetier is a combination slicer and gcode sender. This link goes to the webpage anyone can download repetier from. More information can be found here.


Repsnapper Zero is a combination slicer and gcode sender. For more information on how to use RepSnapper, there is a basic tutorial up on the official Penn State RepRap YouTube channel that you should check out.


This page is for documentation of all projects, issues, and fixes regarding the design and modeling portion of RepRap.

OpenSCAD is used for parametric modelling. It can be downloaded here. The benefit of OpenSCAD is the ability to define a part based on variable parameters which can be changed or adapted based on different needs or even user preference.

A good set of instructions can be found here along with some sample code.


Blender is open source modelling and animation software. It can import and export STL files and works directly with the mesh structure of objects.
