glTF to STL Converter

glTF is the standard format for web and real-time 3D. To 3D print a glTF model you need STL. This converter flattens the scene into one mesh and rotates it to the Z-up orientation slicers use.

Why convert GLTF to STL?

• 3D print models built for the web or AR
• Move assets from Blender, three.js or game engines into a slicer
• Get one mesh file instead of a scene graph

What to know

• Upload a self-contained .gltf (embedded buffers) or a .glb. A .gltf that references a separate .bin file cannot be converted on its own.
• Materials and textures are not kept in STL.

How to convert GLTF to STL

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