Bambu Studio 3D file formats: what opens and how
Bambu Studio is Bambu Lab's slicer for its X1, P1 and A1 printers, and it opens models through File › Import. It opens 3 of the 9 common 3D formats below without conversion; for the rest, convert to STL first.

Which format to choose
3MF and STL are the most dependable choice for Bambu Studio. 3MF can carry colours and plate settings, which matters for AMS multi-colour prints. Bambu Studio is a slicer, so it only needs the shape: colour and textures are dropped, and anything it can't open converts cleanly to STL.
Units and orientation
Bambu Studio works in millimetres and is Z-up. Most problems after an import, such as a model that is invisible, enormous or lying on its side, come from a mismatch with the exporting app rather than a broken file.
- Use Lay on Face (F) to put the flattest side on the plate before slicing.
- If a model imports tiny, Bambu Studio offers to convert from inches or metres; accept it or scale by 1000% in the object panel.
Questions
- What 3D formats can Bambu Studio open?
- Without conversion: OBJ, STL, 3MF.
- How do I get an unsupported format into Bambu Studio?
- Convert it to STL with one of our in-browser converters, then import the STL. In Bambu Studio: File › Import › Import 3MF/STL/STEP/SVG/OBJ/AMF (Ctrl+I).
- Does Bambu Studio keep textures and animation?
- Bambu Studio only uses geometry. Textures, materials and animation are ignored, so a plain STL or 3MF is all you need.
