Our autonomous factory powers itself with real-time, intelligent decisions, allowing a radically faster iteration from design to prototype to production.

Teleport to the center of the production cycle and stay there foreverCut the timeline to final production parts in true, scaled production by orders of magnitude. Stay planted in peak productivity regardless of design cycles. Revise, reconfigure, and deploy with zero downtime.

First molded part, and the first real test of the tool’s assumptions

Plastic’s biggest bottleneckDomestic injection molding is kneecapped by its inability to produce molds effectively. Injection molding shops outsource, and lose money on, the production of molds in order to make back margin on a multi-year scale. What if you don’t operate on that timeline?
