Step 1 – Modeling

There are many computer-aided design (CAD) programs that work well with 3D printing:

  • Tinkercad – Beginner-friendly, browser-based, and free. Great for quick designs.

  • Onshape – A powerful, fully online CAD platform with strong collaboration tools. Free for students.

  • Autodesk Fusion 360 – Advanced CAD software with parametric design features. Free student licenses available.

A good path is to start simple in Tinkercad, then move to Onshape or Fusion 360 as your designs become more complex.

Step 2 – Export as .stl

Once your model is finished and correctly dimensioned, export it as an .stl file—the standard format for 3D printing.

Step 3 – Slice Your Model

Your STL file needs to be processed by a slicer to generate printer instructions (G-code).

  • Recommended: OrcaSlicer – advanced features + user-friendly interface.

  • Other Options: Bambu Studio, PrusaSlicer, Ultimaker Cura.

Step 4 – Start the Print

Save your sliced file as a .gcode onto an SD card or USB drive. Insert it into the 3D printer, select your file from the printer’s menu, and start the print.
