How Protolabs turns CAD files into parts in under 24 hours
Marc Kermisch, CTO and AI Officer at Protolabs, explains how the company uses AI and simulation to turn CAD files into physical parts in under 24 hours across CNC machining, 3D printing, injection molding, and sheet metal. He details how ProDesk flags manufacturability issues like tight tolerances and ejector locations, while internal AI tools optimize print box placement and visual quality inspection. Kermisch also discusses the critical tradeoffs between prototyping and production, highlighting common design mistakes such as non-uniform wall thickness and missing draft angles that engineers must address before tooling.
