STEP to 3MF — each body of a CAD file as its own object
Convert a STEP or IGES file to 3MF for Bambu Studio, PrusaSlicer or OrcaSlicer: each body as its own object, placed as in the drawing, in millimetres. In your browser, nothing uploaded.
Saves model files for your slicer, never printer code. Opened and sliced in PrusaSlicer, OrcaSlicer, Bambu Studio and Cura.
About this conversion
A multi-body STEP — a box and its lid, a part and its pins — becomes one 3MF with each body as its own object, so the slicer can print them on one plate or move them apart. The 3MF stores every point once and exactly, so the slicer sees the same closed solids that were read from the drawing.
Just want to look inside it?
The same tool without converting anything: open the file and read it.
The same model, other ways
The model stays open after it is read, so the format is picked at the end: the same model can leave here as STL (.stl) or OBJ (.obj). Before that you can repair it, cut it, make it smaller or combine it with another one.
Questions
- Will the parts keep their positions?
- Yes — each body stays where the drawing put it. Use “side by side” to spread them out on the bed.
