Preparing Your Model for Print


ChiTuBox Specifics

The ELEGOO MARS 3 uses ChiTuBox as its slicer.

Once your environment is set up:


optional: if this is a job you see yourself returning to, you can save your workspace (as well as your supports) as a project. Exit out of the Slice screen, click the three horizontal bars in the top left corner of your screen, click Save Project > All Models. The .CTB file extension indicates the slicer file that you take to the printer, and the .chitubox  file extension indicates the project workspace file that helps you manage your 3D models and supports for printing.
