Riley first worked on 3D printing in his master’s research where he developed heart tissue scaffolds. He’s since been hooked on the idea that radical innovation can come from using existing materials in new ways. He’s the CTO and Cofounder at Arris Composites, a Berkeley-based startup that has developed a new manufacturing process for mass producing composite parts. He also cofounded Arevo, the first company to introduce advanced polymer composites to 3D printing and demonstrate true 3D printing. Riley has filed over 20 patents in the areas of 3D printing and composites. Previously, he worked at TNO in the Netherlands as the innovation program manager developing automated 3D printing technologies for industrial, end-use applications. Riley started his career in medical working at Stryker as an investigative engineer, solving product failures and building robust designs for new products. Riley received his BS in Bioengineering and Materials Science and Engineering at UC Berkeley and MS in Materials Science and Engineering also at UC Berkeley.
