✦ AI 3D design · game export · print on demand

Sketch it.
Make it real.

Upload a sketch or describe your idea. ProtoMaker turns it into production-ready 3D files — watertight STEP/STL, game-ready GLB/FBX, fabrication drawings, and a live 3D-print quote. One straight pipeline, no CAD expertise needed.

From idea to physical object in three steps

1

Describe it

Upload a sketch or photo, write a description, optionally give dimensions. AI auto-guesses the rest.

2

Generate & verify

AI builds a parametric CAD model, checks it's watertight and interference-free, and audits it like a real engineer.

3

Export or print

Download STEP/STL for manufacturing, GLB/FBX/OBJ for Unity & Roblox, or order a multi-color 3D print right from your dashboard.

Everything you need, nothing you don't
