Partomat turns a sentence into a parametric CAD model you can tune with sliders, then sends it to a print shop. Choose from 14 AI models, or run several at once and keep the best design.
Early access: explore the example designs for free. Paid AI generation opens soon; you can already connect your own OpenRouter account.
“A wall clip for a 32 mm pipe with two M4 screw holes”
Say what it is, what it attaches to and the sizes you know. The model writes a real parametric program, not a frozen mesh.
Every important dimension becomes a slider. Change wall thickness or hole size and the part rebuilds instantly. Or ask for changes in words.
Partomat picks the best process for each part, from FDM to machining or moulding, with prices. Order through us or compare quotes from other shops.
Approximate cost of a typical design turn. Prices follow each model provider. Cheap models handle simple brackets; frontier models handle assemblies. Compare mode runs up to four side by side, and your votes rank them on the leaderboard.

Each part of a design gets its own recommendation based on its shape, what it has to withstand and how many you need: a printed housing, a machined bracket and a moulded clip can come from three different shops. Prices update as you move the sliders.
PLA FDM
Cheap and stiff. Prototypes, fixtures, indoor parts.
2–4 days, up to 250 × 210 × 210 mm
PETG FDM
Tougher than PLA and handles heat and moisture. Functional parts.
2–4 days, up to 250 × 210 × 210 mm
TPU 95A FDM
Flexible rubber-like parts: gaskets, bumpers, grips.
3–5 days, up to 250 × 210 × 210 mm
Standard resin SLA
Smooth surfaces and fine detail. Visual models, small precise parts.
3–5 days, up to 200 × 125 × 210 mm
Nylon PA12 MJF
Strong, isotropic, no supports. End-use parts and small batches.
5–8 days, up to 380 × 284 × 380 mm
Aluminium 6061 CNC
Machined metal. Rough estimate; an engineer confirms the final price.
7–12 days, up to 400 × 300 × 150 mm
