3D Valley

What is 3D Valley?

3D Valley turns a photo of one object, or a one-sentence description, into a textured 3D model in about a minute. The free runs use TRELLIS.2, an open-weights model, on a daily allowance per visitor, with no account or email needed. For more detail you can pick other engines by name and pay per model: TRELLIS.2 Pro, Tripo 3.1 Standard and Detailed, and Hunyuan3D 3.1 Pro, which the site says makes clean, closed meshes that print well.

Every result downloads as STL, OBJ or GLB, and the downloads are made in your browser. Raw generated meshes often have holes and loose bits, so the site points you to its Repair tool, which seals the model into one solid, scaled in millimeters. Other free tools include remesh, reduce, retexture, a viewer, format conversion and a print cost calculator that works out filament cost and what to charge. There is also a search across CC0 models and textures from Poly Haven, ambientCG and Sketchfab.

Everything is free within the daily limit. After that, or for the other engines, you buy credits at 1 cent each with no subscription: $15 for 1,500 up to $100 for 13,000, valid for 12 months. An image-to-3D run costs 5 to 100 credits depending on the engine. Buying credits needs a free account. It suits makers who want to try AI 3D without signing up and need a repair step before slicing.

What you can make

• Figurines and props from a photo
• Decor objects
• Models from a short description
• Repaired, print-ready versions of generated meshes
