3MF to STL Converter

3MF is the project format used by modern slicers. Many tools, printers and model sites still only take STL. This converter extracts the mesh from a 3MF file and saves it as a standard STL.

Why convert 3MF to STL?

• Share a model with someone whose software only reads STL
• Upload to model repositories that require STL
• Edit the mesh in tools without 3MF support

What to know

• STL has no colors, materials or print settings, so those parts of the 3MF are dropped.
• Multi-object 3MF files are merged into one STL mesh.

How to convert 3MF to STL

1. Select your .3mf file above.
2. Click "Convert to STL".
3. The .stl file downloads automatically with the same name as your original.
