Why convert 3MF to GLTF?
Turn a 3MF print project into an open glTF scene for viewers and web tools.
How it works
Drop your .3mf file above and download the .gltf. The conversion engine (Assimp, compiled to WebAssembly) runs inside the page, so it works the same on Windows, macOS, Linux and ChromeOS without installing anything.
3MF vs GLTF
3MF (3D Manufacturing Format): 3MF is a ZIP container of XML created by the 3MF Consortium (Microsoft, HP, Autodesk and others) as a modern replacement for STL. Unlike STL it records units, colours, materials and multiple objects. Used by: PrusaSlicer, Bambu Studio, Cura and Windows 3D Builder.
glTF (GL Transmission Format): glTF is the Khronos Group’s open standard for delivering 3D models, often called “the JPEG of 3D”. A .gltf file is JSON that describes meshes and physically based (PBR) materials, with binary data and textures alongside or embedded. Used by: three.js, Babylon.js, Blender, Sketchfab, and developers who want a readable, editable model file.
Quality notes
Object meshes and basic colours convert; print settings and plate data stay behind in the 3MF. glTF output is a .gltf file plus a .bin file with the geometry, so the download is a ZIP containing both — keep them together.
Common use cases
Displaying print projects in web galleries; loading 3MF designs into Blender via glTF.
