AI models to the printer

Text-to-3D tools and AR pipelines speak glTF/GLB; printers don't. We pull all mesh nodes out of the scene graph, apply their transforms, merge everything into one mesh and export STL. Materials and animations are dropped — slicers ignore them anyway.

Frequently asked questions

My GLB came from an AI generator — will it print?
It converts fine, but AI meshes are often non-manifold. If the slicer complains, run the STL through our repair tool — it fixes winding, duplicates and small holes automatically.
Is this converter free?
Yes — up to 10 conversions a day and files up to 25 MB, no account needed. Larger files (up to 60 MB) and high-detail STEP output use credits ($9 for 20). Everything runs server-side on real geometry kernels, and failed jobs auto-refund.
What happens to my files?
Files are uploaded only to run your conversion and stored briefly so you can download the result. We don't share them, mine them or train on them. See our privacy policy.
