Nick Pinkston is interested in digital manufacturing technologies like 3D printing, CNC milling, and laser cutting. He discusses how these technologies enable complexity, speed, and customization in manufacturing through computer-aided design and manufacturing. However, he also notes these technologies have limits in terms of cost and available materials. Pinkston believes these technologies can enable customization and modularity while questioning if there is too much hype around them or if widespread adoption is still in the future.
