AI STL Generator

What is AI STL Generator?

AI STL Generator turns a text prompt or a JPG or PNG image into a 3D model for printing. You can upload one picture or several angles of the same object, pick the Basic or Pro AI model, choose STL or 3MF output, set a character pose (none, A-pose or T-pose) and let it scale the model to an estimated real-world height with the origin at the base.

Every model runs through an automatic printability check for non-manifold edges, inverted normals and zero-thickness walls, followed by repair. The site also has a separate Remesh and Repair tool to change mesh density, cut the polygon count and flatten the base, plus a printability checker, STL repair, SVG to STL and STL to 3MF converters and model viewers. Downloads come as STL or 3MF for printing, with OBJ and GLB also listed.

The free plan gives 5 credits a day when you log in and check in, on the Basic model only and for non-commercial use. A generation is shown at 5 credits on the homepage, with Ultra detail adding 5 more, while the pricing FAQ says 10 to 20 credits is typical. Maker is $9.99 a month for 200 credits and Pro $24.99 for 500 (20% less yearly), and one-time packs run from $4.99 for 50 credits to $29.99 for 500. It suits hobby makers who want a small free daily allowance and 3MF output.
