3D & CAD Generation — straight answers

What are the best free AI 3D model and CAD generators?

Flocci AI Tools lists 10 AI 3D model and CAD generators, ordered free tiers first: Hunyuan3D-2 (Tencent), TRELLIS (Microsoft), Meshy, Polycam and Rodin (Hyper3D). All of them are free or have a free tier. Every entry states what it uniquely does, not a score.

Are there completely free AI 3D model and CAD generators?

Yes — 2 of these are marked fully free with no paid plan attached: Hunyuan3D-2 (Tencent) and TRELLIS (Microsoft). The rest are freemium, trial or paid, and each row states which.

What should I look for in AI 3D model and CAD generators?

Start with what you need to do: turn a prompt or photo into a usable 3D asset. Then check the pricing tier, because "free" here means no paid plan at all while "freemium" means a free tier under paid plans. Every tool on this page lists both.
