GLB → STL: what you should know
GLB to STL is the 'found it online, want to print it' conversion: Sketchfab models, game assets and web-viewer files come as GLB, and your slicer wants STL. This converter extracts all the scene's geometry — with each node's transforms applied — and writes it as a print-ready STL.
The critical thing this converter gets right: GLBs often have scaled or rotated nodes (a scene can hold a mesh at 0.01x with a node scaling it 100x). Here transforms are baked into the vertices before export, so the STL comes out with the shape and proportions you see on screen — not a tiny or giant version.
What doesn't travel into the STL: textures, PBR materials and animations, which the format can't represent. Also note many GLB models are made to render, not to manufacture — open meshes, zero-thickness walls, floating parts. The mesh repair tool's diagnosis tells you in seconds whether it's printable.
Frequently asked questions
Does it work with Draco-compressed GLBs?
Yes — the viewer ships the Draco decoders, so compressed GLBs open and convert normally. Decompression happens in your browser during loading.
The model was animated — what happens to the animation?
The STL captures the model's rest pose (bind pose): animations don't exist in STL. If you need to print a specific pose, fix it first in Blender (applying the armature) and export that state.
Why isn't my converted GLB printable?
Game and web assets are modeled to look good, not to be manufactured: loose faces, open meshes and zero thickness are common. Run the STL through the mesh repair tool — it closes holes and removes fragments — and check the watertight test in model info.
