Which AI 3D generators make models that actually print?
We run the same set of images through each generator and check every file for holes, thin walls, floating bits and wobbly bases. Then we score it out of 100 and show where every file came from. The first full monthly run is coming soon. Until then, here is a preview built from sample files.

Generators with fewer than 3 sample models are shown but not ranked. Prints OK means a score of 65 or more. Cost is the cheapest API route we found for one untextured mesh. See each generator page for sources.
