AI-Powered Manufacturing Engine
North 41 builds Lithic AI — an autonomous pipeline that turns a plain-English description into verified STEP geometry, G-code toolpaths, a manufacturability report, and a costed quote. It is how engineers design and quote precision parts in minutes instead of days.
Natural Language → Verified CAD
Describe a part in plain English. Lithic plans it, builds parametric STEP geometry, then checks every dimension and feature against your intent before it moves on. Typical end-to-end time: 3–6 minutes for a complex multi-feature part.
Where it is strong today: across core prismatic families — spur gears, pneumatic/hydraulic manifolds, bearing & pillow-block housings, heat sinks, keyed shafts, enclosures, brackets, fixture plates and bolt-circle plates — Lithic builds verified, machine-ready geometry to spec (the parts shown below are real pipeline output). More complex turned and threaded work — multi-lead threads, swept passages, freeform profiles — is still in active development and is routed to a human engineer rather than shipped. Backed by 1,340+ automated tests.
It Tells You What It Can't Do
Lithic works within a deterministic 2.5–3 axis machining envelope. When a request falls outside it — a freeform turbine blade, a 5-axis impeller, an organic lattice — it routes the job to a human engineer instead of shipping a wrong model. No fabricated geometry, ever.
Every part also passes dimensional verification, manufacturing-rule governance, FEA, and visual QA — with automatic redesign loops — before any tool moves.
Real Geometry Lithic Generates
Every image below is an actual render of STEP geometry our pipeline generated from a one-line description — modeled on real Japanese and German precision components, from Swiss-turned micro parts to fixture and automation hardware. These are AI-generated CAD models, not parts North 41 has machined — but each carries correct bores, clamp slits, cross-drilled galleries, gear teeth and seat bores, ready for CAM.

Cylinder Mounting Flange
ISO 15552 front flange: central cylinder bore + 4 corner mount holes. 80 × 80 × 10 mm. Die-cast aluminum.
Pneumatic Manifold Block
Cross-drilled main gallery + port row on pitch + side feed. 55 × 25 × 25 mm. A5052 aluminum.

Also in the library: dowel & gauge pins, press-fit bushings, hex standoffs, set screws & knurled nuts, U-channels, pocketed & bolt-circle plates, toe/strap clamps, and gripper bodies — 30+ parametric part families spanning Ø3 mm Swiss-turned parts to 90 mm fixtures.
