Asteria

3MF to STL

Turn 3MF 3D print file files into STL 3D model files on your own Mac, Windows or Linux computer. Asteria is free, works offline, and never uploads your files.

How to do it

  1. Download Asteria and open it. It's free and needs no account.
  2. Drop your 3MF files onto its window, or press ⌘O (Ctrl O on Windows) to choose them. Drop as many as you like.
  3. Type 3mf to stland pick Convert to STL. Write the mesh as binary STL for 3D printing.
  4. Press ⌘↵ (Ctrl ↵ on Windows) to save. The STL files appear next to the originals, which stay exactly as they were.

What it needs

Nothing. This conversion is built into Asteria, so it works the moment the app is open, even offline.

How it was tested

A real 3MF file was converted on Linux, and the STL that came out was opened and checked with Assimp to make sure it is what it says it is.
