AI designs a full flat-six engine from a text prompt — tool-free assembly, FDM-printable
ycombinator · x · 2026-09-08
Adam, an AI CAD system, generated a complete flat-six engine—six pistons, connecting rods, a counterweighted crankshaft, split crankcase, and flywheel—as an editable parametric CAD file, all modeled from a written description.
- The engine assembles without tools; Adam sized clearances for FDM printing, using friction fits and printed fasteners.
- Change handling impressed the team: adjusting piston diameter mid-project triggered automatic rework of bores, rods, and crank throws.
- The team is now working with a small group of hardware teams running their engineering process through Adam.
