Micromanufacturing has historically been trapped between traditional mechanical machining (limited to 10s of microns) and semiconductor lithography (planar, mask-bound, and restricted to silicon chemistry). Atomic Machines emerged from 6 years in stealth with the "Matter Compiler," an all-digital platform that fabricates 3D micro-machines with moving parts down to single-digit microns directly from code without masks, molds, or per-product tooling. Their first commercial device is the PrimeSwitch (PS-150): an electromechanical power relay for 800-volt AI data center architectures that opens in 50 microseconds, measuring 9.5 mm across and 3 mm thick. atomicmachines.com
