When to convert 3MF to OBJ
You have a 3MF and need OBJ for a modeling tool (Blender, Maya, 3ds Max) or a pipeline that expects named vertex data instead of 3MF’s zipped XML. Drop the 3MF above for a geometry-clean OBJ, entirely in your browser.
3MF vs OBJ: what’s the difference?
3MF (3D Manufacturing Format) is a modern, zip-based container that stores geometry together with color, materials, print settings and multiple objects — what Bambu Studio and PrusaSlicer save by default. OBJ is the plain-text mesh format Blender, Maya and 3ds Max read, storing geometry as named vertices and faces. Converting 3MF to OBJ pulls the clean geometry out of the print file into a form any 3D modelling tool imports directly.
What 3MF → OBJ keeps and drops
Preserved
- ✓Full mesh geometry, every triangle
- ✓Real-world scale and dimensions
- ✓Model orientation
Dropped
- ✗Color and per-object materials — not re-exported into OBJ/MTL
- ✗Print settings, supports and build-plate layout
- ✗Separate objects, which are merged into a single mesh
How to convert 3MF to OBJ
- 1Drop your .3mf file onto the box above, or click to browse.
- 2The file is unzipped and parsed in your browser — nothing is uploaded.
- 3Check the 3D preview, then click “Convert to OBJ”.
- 4A .obj file downloads, ready to import into Blender or Maya.
3MF to OBJ carries geometry only — color, materials and separate objects do not survive into the OBJ. If you need to keep the color for a full-color print, leave the file as 3MF instead. Materials must be reassigned in your 3D tool after import.
3MF to OBJ — FAQ
Do color and materials carry into the OBJ?
This pass converts geometry only — 3MF color and material assignments aren’t re-exported into OBJ/MTL. Reassign materials in your 3D tool after import.
Is my file uploaded?
No. Conversion runs locally in your browser tab; your 3MF never leaves your device.
