GLTF to 3MF
Turn glTF 3D model files into 3MF 3D print file files on your own Mac, Windows or Linux computer. Asteria is free, works offline, and never uploads your files.
How to do it
- Download Asteria and open it. It's free and needs no account.
- Drop your GLTF files onto its window, or press ⌘O (Ctrl O on Windows) to choose them. Drop as many as you like.
- Type convert to 3mfand press Enter. Write the mesh as a 3MF print package.
- Press ⌘↵ (Ctrl ↵ on Windows) to save. The 3MF 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 GLTF file was converted on Linux, and the 3MF that came out was opened and checked with Assimp to make sure it is what it says it is.
