## Summary

Riley Reese, Co-Founder and CEO of Eris, explains how his company uses Additive Molding™ to manufacture high-performance composite parts at scale, combining the volume of molding with the material efficiency of additive techniques. He details the process of creating pre-preg filaments to control fiber alignment along stress lines, enabling applications in footwear, consumer electronics, and wearables that outperform traditional injection molding or 3D printing. Reese also discusses his background in biomaterials, including work on biodegradable heart tissue scaffolds at UC Berkeley and Stryker, and highlights Eris's focus on sustainability through recyclable thermoplastics and bio-based resins.
