What is 3DM?

3DM is the native file of Rhino, used widely in industrial, jewellery and architectural design. It stores NURBS surfaces, SubD objects, meshes and block instances.

Full name
Rhinoceros 3D model (openNURBS)
Type
Exact CAD geometry
Used in
Rhino, Grasshopper, KeyShot, Blender (with add-on)
Strength
Rich surface modelling data from Rhino.
Limits
Surfaces are converted using the render meshes Rhino saves in the file.

What is 3MF?

3MF is the modern 3D printing format from the 3MF Consortium. Unlike STL it records units, colours and multiple objects in one compressed file, and it is the native project format of Bambu Studio and PrusaSlicer.

Full name
3D Manufacturing Format
Type
Triangle mesh
Used in
Bambu Studio, PrusaSlicer, Cura, Windows 3D Viewer, OrcaSlicer
Strength
Keeps units and multiple parts; smaller than STL.
Limits
Not used by CAD or game software.

Good to know

Rhino saves a display mesh for every surface it has shown in shaded view. We use those meshes. If a file was saved with "Save Small", open it in Rhino, switch to shaded view and save it again.

Questions

Are materials and textures kept?

Colours and texture coordinates are carried over when 3MF supports them. 3MF does not store textures, so only the geometry and colours carries over.

Will my model be upside down?

No. 3DM and 3MF may use different "up" directions, and we rotate the model so it stands the same way in your software.

Are my files uploaded?

No. The conversion runs inside your browser.
