Tripo vs HunYuan 3D vs Rodin vs Meshy vs Hi3D: which AI 3D model generator should you use?

Makerful runs five of the leading image-to-3D models behind one chat, so I see the same pictures go through Tripo H3.1, HunYuan 3D v3.1, Rodin Gen-2.5, Meshy 7.1 and Hi3D v3.0 every day. Nobody wins every time. Here is how I pick, and what each one costs in credits (one credit is about one US cent of what the provider charges us).
The short version
- Tripo H3.1 is the default: fast, clean figures, good textures. 30 credits textured, 60 for the detailed mesh with HD textures, and a cheaper geometry-only draft.
- HunYuan 3D v3.1 makes dense, detailed meshes and is strong on hard-surface shapes. 23 credits for a quick textured draft, 38 for the full build.
- Rodin Gen-2.5 is the photoreal one: surface detail and PBR textures at one tier, 40 credits.
- Meshy 7.1 is premium: the best textures, at 120 credits (160 at 4k geometry).
- Hi3D v3.0 is the top-rated model for detail and textures, and the priciest: 200 credits, high tier only.
Comparison table
| Model | Credits on Makerful | Strength | Watch out for |
|---|---|---|---|
| Tripo H3.1 | 30 textured, 60 high | Clean, printable figures; quick | Soft on very fine surface detail |
| HunYuan 3D v3.1 | 23 draft, 38 textured | Dense meshes, hard-surface shapes | Textures plainer than Rodin or Meshy |
| Rodin Gen-2.5 | 40 | Photoreal surface detail, PBR | One tier only; 1M-triangle files are big |
| Meshy 7.1 | 120, 160 at 4k | Best textures for painted looks | Costs four times Tripo |
| Hi3D v3.0 | 200 | Top-rated detail and textures | Overkill for single-colour prints |
The Studio shows the exact credits before every build, so you never guess.
How I choose
- Printing in one colour? Texture quality is irrelevant. Use Tripo, and only go to its 60-credit high tier or to HunYuan if the surface detail (fur, scales, engraved text) is the point.
- Figure or character with a painted look? Rodin first; Meshy if the texture still is not good enough; then the filament-painting preview to see which colours you would need.
- Mechanical object, hard edges, boxes with lids? HunYuan, or skip the mesh models entirely and use the CAD agent, which produces real parametric geometry with dimensions.
- Not sure? Run the HunYuan draft first. 23 credits tells you whether the concept picture reads as a 3D shape at all; most failed prints trace back to a bad concept, not a bad model.
Why run them in one place
Each of these providers sells its own subscription, typically $10–$30 a month each, and the quality lead changes every few months. Makerful bills per generation from one credit balance, so you can switch models per job and let the agent pick when you do not care. The Studio also does the parts the generators do not: concept pictures first, mesh repair, scale in millimetres, and STL, 3MF, GLB and OBJ exports.
Frequently asked questions
Which AI 3D generator is best for 3D printing?
For most prints, Tripo H3.1: watertight meshes, good proportions and a reasonable price. Use HunYuan 3D for hard-surface objects and the premium models only when the surface detail matters.
Which one is the cheapest?
HunYuan 3D v3.1's draft tier at 23 credits per model. It is a good first pass, and good enough for many small single-colour prints.
Can I use the same picture with several models?
Yes. On Makerful you pick a concept picture once and can build it with any model; the credits are charged per build.
Do I need a separate account with Tripo or Meshy?
No. One Makerful account runs all of them. A new account starts with 80 free credits.
