Astra 3D puts the leading 3D AI models behind one generator.
AI 3D Model Generator
Turn one image or a few words into a complete 3D model — add a back photo so nothing comes out flat, auto-rig your characters, get a print-ready STL, and switch between every top 3D AI model in one account.

Hi3D 3.0 · 08 / 08What Is an AI 3D Model Generator?
Upload an image to 3D, or type a description for text to 3D, pick the model that fits the job, and download the result as GLB or STL for Blender, Unity, Unreal or your slicer.
Image to 3D Model With a Complete Back Side
Add a side or back photo of the same object and the AI 3D model generator builds the parts one photo cannot show — no flat, blurry back.
Upload 1–4 views
Image to 3D works from the front alone; a back or side photo fills in what the camera missed.
Works on the models built for it
Hunyuan3D, Tripo, Meshy and Hi3D read multiple views.
Hunyuan3DTripoMeshyHi3D
Shapes that hold up from every angle
Turn the model around and the back has real depth and detail.
Auto rig
Auto Rig Your 3D Character in One Click
Astra 3D adds a skeleton and skin weights to your generated character, so it is ready to animate in Unity, Unreal or Blender without an hour of manual weight painting.
Skeleton and skin in one step
No export to another tool and back.

Ready for your engine
Download a rigged model and drop it into your game or animation project.
Built for game developers
Props and characters go from image to playable faster.
No Picture? Describe It and Get a 3D Model
Type what you want and Astra 3D first makes a clean reference image built for 3D — plain background, clear front view — then turns it into a 3D model, all in one place.
Start from words
"a wooden treasure chest with iron corners" is enough.
A reference image made for 3D
Clean light and a clear shape give the model a better start.
Print-Ready STL From Your AI 3D Model
Astra 3D prepares the mesh for printing before you slice it — thin walls thickened, holes closed and a flat base added — so the STL goes straight to your printer.
STL
Watertight mesh
Closed holes so your slicer reads one solid object.
Thin parts made printable
Walls thickened where they would break.
A flat base
The model stands on the bed without extra supports under it.

High-detail models keep the fine edges, text and color you need for close-ups, renders and prints.
Download Your 3D Model as GLB or STL
Every Astra 3D result downloads as GLB for games, web and Blender, or STL for 3D printing — as many times as you need, at no extra credit cost.
GLB
Textures included; opens in Blender, Unity, Unreal and three.js.
STL
Shape only, for Cura, Bambu Studio, PrusaSlicer and other slicers.

Upload a photo or type a description, choose a 3D model, and download your 3D model — most results are ready in a few minutes.
AI 3D Model Generator vs Meshy & Tripo
Meshy and Tripo each run their own models; Astra 3D lets you use theirs and five more from one account, so you can pick the best 3D model for each image.
| Feature | Astra 3D | Meshy | Tripo |
|---|---|---|---|
| 3D AI models | 8, from several companies | Meshy only | Tripo only |
| Same image on another company's model, no re-upload | Yes | No | No |
| Cheapest monthly plan | $9.9 | $20 | $20 |
| Credits in that plan | 450 | 1,000 | 3,000 |
| Credit packs that never expire | Yes | Yes | Only on top of a plan |
Looking for a Meshy alternative or a Tripo alternative? Use both — and six more — from one account.

An AI 3D model generator turns an image or a text description into a textured 3D model. Astra 3D runs eight leading 3D AI models, so you can pick the one that suits your object and download it as GLB or STL.
Yes. Upload a JPG, PNG or WebP photo, pick a model and generate. Add a side or back photo of the same object and the model builds the hidden side instead of guessing it.
It depends on the job: Hunyuan3D Pro keeps the most detail and color, Tripo H3.1 and Tripo P2 suit characters and game assets, Hi3D 3.0 is built for 3D printing, and Fast draft gives you a shape in about 30 seconds. On Astra 3D you can run the same image on several and keep the best.
Astra 3D includes Meshy 7.1, Tripo H3.1 and Tripo P2 alongside Rodin, Hunyuan3D, TRELLIS.2 and Hi3D, so you can use them from one account instead of subscribing to each.
Yes. Download STL and Astra 3D prepares the mesh for printing first — holes closed, thin walls thickened and a flat base added — so it goes straight into your slicer.
Yes. Auto-rig adds a skeleton and skin weights in one click, ready for Unity, Unreal or Blender.
GLB with textures for games, web and Blender, and STL for 3D printing. Downloads do not use credits.
Each model has a fixed credit cost shown on the Generate button. Monthly plan credits reset on your billing date; credit pack credits never expire. If a model fails or times out, the credits go back to your balance.
Yes. Models you generate on Astra 3D can be used in commercial projects.
