AI 3D Model Generator

An AI 3D model generator creates a 3D mesh, usually with textures, from a single image or a short text description. The model has learned how objects look from every side, so it predicts the full shape, including the parts your input doesn't show. On Krea you upload an image or write a prompt, pick a model such as Hunyuan3D, TRELLIS, Tripo, Rodin, or Meshy, and get a model you can rotate and download.

Upload the image at the top of this page and click Generate 3D model. Krea opens the 3D tool with your image loaded as the input; click Generate there and the model appears in a 3D viewer. From there you can rotate it, try another model on the same image, or download it.

There's no single best one; it depends on the object and what you need it for. Hunyuan3D 3.1 Pro gives high-fidelity models with optional PBR materials, Meshy V7 focuses on clean topology, Tripo H3.1 makes sharp geometry at low cost, Rodin V2.5 builds detailed, well-structured meshes, and TRELLIS 2 is a native 3D model for high-quality assets. Krea runs all of them in one tool, so you can try the same input on several; our guide to the best AI 3D model generators compares them in more depth.

Not as finished, textured models. ChatGPT can write code that builds simple geometry, such as OpenSCAD or Blender Python scripts, but it isn't a 3D generator that turns a photo or a prompt into a textured mesh. A dedicated 3D generator does that: upload the image or paste your prompt here and download a GLB, OBJ, FBX, PLY, STL file.

Yes, you can start for free. A free Krea account gets 100 compute units a day, and Hunyuan3D-2.1 is open to free accounts at about 23 units per model, so that covers about 4 3D models a day. Hunyuan3D 3.1 Pro, TRELLIS 2, Tripo, Rodin, Meshy, and the other models need a paid plan, which also adds more compute and priority jobs.

A sharp, well-lit image of one object, fully in frame, on a plain background works best. Busy scenes, heavy shadows, and cropped objects make the shape harder to read. JPG, PNG, WebP, and HEIC all work; if the background is cluttered, clean it up first with the background remover.

Yes. Type a description such as "a ceramic robot with a glossy orange finish" in the prompt box and Krea generates it in 3D. Text gives the AI more freedom, so for full control over the look, create the exact image first with the AI image generator, then turn that image into a 3D model.

Usually between about 45 seconds and 180 seconds, depending on the model. Those are the estimates the 3D tool shows for its fastest and slowest models, and busy times can take longer. Mesh-only generations skip texturing and finish sooner.

Good enough to use directly for concepts, props, renders, and prints, and a strong starting point for hero assets. Models are textured by default, and Hunyuan3D 3.1 Pro can add PBR materials for realistic lighting in game engines and renderers. For real-time use you may want to reduce the polygon count or retopologize, as with most AI-generated meshes.

You can download every model as GLB, OBJ, FBX, PLY, STL. GLB keeps the textures in a single file and opens in most 3D apps and web viewers, FBX and OBJ suit game engines and 3D software, and STL is what 3D printing slicers expect.

Yes. Download the model as STL and open it in your slicer. AI-generated meshes can have thin parts or small holes, so check the model there (most slicers repair simple issues), scale it, and add supports before printing.

Yes. Blender imports GLB, FBX, and OBJ directly, and Unity and Unreal Engine import FBX and OBJ, plus GLB through their glTF importers. Download the format your pipeline uses from the 3D tool.

Yes, on a paid plan. Krea's paid plans include a commercial license for what you generate, including 3D models for games, products, and client work. Generations on the free plan aren't licensed for commercial use, and you should only use input images you own or have permission to use.

No. Krea doesn't add a watermark or logo to the 3D models you download, on any plan. The files are plain meshes and textures you can edit like any other model.

Your image is saved to your Krea account and sent to the 3D model you choose to create the result; models such as Tripo, Rodin, Meshy, and TRELLIS run with third-party providers. Only upload images you have the rights to. Our privacy policy covers storage, deletion, and data use in detail.

You can try. Most 3D models are tuned on English prompts, so English gives the most predictable results, but many also understand other languages. If a prompt in your language misses, rewrite it in short, concrete English, or start from an image instead, which works the same in any language.

You don't have to choose: Krea includes Meshy V7 alongside Hunyuan3D, TRELLIS, Tripo, and Rodin. That means you can compare several generators on the same image or prompt in one tool, with one account and one plan, and use the same account for AI images and video.
