Export 3D models for printing (.stl)
Turn a .glb or .fbx — including AI-generated characters — into a slicer-ready STL with sizing, orientation and cleanup handled for you.
Open Rig Bake — free, in your browserNo sign-up. No upload — models stay on your machine. Works in any WebGL 2 browser.
AI-generated models make great miniatures and figurines, but slicers are picky: they want millimeter units, Z-up orientation and watertight geometry. Rig Bake's STL export dialog handles the conversion and tells you honestly whether the mesh will print.
Print-ready conversion
- Target size presets — scale the longest side to 25, 50, 100 or 200 mm.
- Z-up orientation — matches slicer conventions automatically.
- Cleanup for printing — weld duplicate vertices, drop degenerate triangles and remove tiny floating islands that would print as debris.
- Pose first, print second — because Rig Bake is an animation tool, you can scrub to any animation frame and export the character in that pose.
Live printability report
Before you download, the dialog reports physical size, triangle count, number of separate pieces, open-edge count and a watertight verdict — so you know about problems before wasting filament, and can fix holes with the Model Doctor first.
Frequently asked questions
Can I print a Meshy AI or Tripo character?
Yes — import the .glb, run the repair fixes (weld, hole fill), pose it on the timeline if you like, and export STL with a size preset. The report tells you if the mesh is watertight.
Why does my slicer show a tiny or gigantic model?
Unit mismatch — glTF works in meters, slicers in millimeters. Rig Bake's size presets scale the longest dimension to a real-world print size for you.
Does STL export keep colors or textures?
No — STL is geometry-only by specification. For color printing use a format like 3MF from another tool; for resin/FDM miniatures STL is exactly right.
