FBX to 3MF Converter

Convert an .fbx into a .3mf for your slicer. Unlike STL, the 3MF keeps each mesh as a separate object and carries the material colours.

How to convert FBX to 3MF

Drop the .fbx above and check the size under the view.
Keep 3MF selected and click Download 3MF.
Open the 3MF in your slicer and assign filaments to the colours.

What is kept

Material base colours, written as a 3MF colour group — slicers show them and let you map each to a filament.
Each top-level node as its own object, with its meshes as parts.
Real size in millimetres and Z-up orientation.
Texture colours are not converted, only material colours. Rigged models come in their rest pose.

Frequently asked questions

Does it convert texture colours to filaments?

No. Only the flat colour of each material is kept. Painted texture detail would need a texture-to-colour conversion that this tool does not do.
