Convert GLB to STL for 3D printing
Extract visible mesh geometry from a binary glTF model and download an STL entirely on your device.
GLB → STL
Convert on this device
STL cannot store GLB textures, materials, rigging or animation. Only mesh geometry is exported, and game-ready models may need wall thickness or mesh repair before printing.
What changes from GLB to STL?
GLB can bundle meshes, scene nodes, animation, textures, cameras and lights. STL contains only triangles. The conversion preserves mesh transforms and surface geometry while leaving scene presentation data behind.
How to convert a GLB model
Drop a .glb file, select Convert to STL and download the binary result. Inspect the STL in a slicer and repair non-manifold or open surfaces before printing when the original asset was designed for real-time rendering.
FAQ
Questions about GLB conversion
- Does GLB to STL preserve textures?
- No. STL does not have a standard texture or PBR material channel, so the converter exports geometry only.
- Can an animated GLB become an animated STL?
- No. STL is a static surface format. The model is exported from its loaded scene state without animation tracks.
- Will every GLB be ready to print?
- Not necessarily. Visual models can have open surfaces, intersecting parts or zero-thickness planes. Use your slicer's repair checks before printing.
