Paul shares how NASA has expanded the range of available materials, pioneering alloys like GR COP and GRX 810 for extreme environments, and how these innovations are now being used in industries beyond aerospace. The conversation covers the rapid acceleration of material development through advanced modeling and early AI adoption, the technical hurdles of scaling up to larger parts, and the realities of additive manufacturing in space—from lunar construction to the potential of asteroid mining. Paul also discusses the importance of learning from failures, NASA’s commitment to public data sharing, and his passion for mentorship and STEM education, both at work and at home. Whether you’re an industry veteran or new to additive, this episode offers valuable insights and inspiration. Sign up for the NASA Metal AM Master Class today: Metal AM Master Class with NASA | EOS Store - US 2:00 - The Evolution of Additive Materials NASA is expanding material options and redefining what’s possible with additive. 7:45 - Material Highlights & Cross-Industry Applications Paul discusses GR COP, GRX 810, and their applications beyond aerospace. 13:45 - AI, Machine Learning & Accelerating Alloy Development AI and modeling are accelerating how new alloys are developed. 17:50 - Scaling Up: Big Parts & NASA’s Role NASA is driving the shift toward larger, room-sized additive parts. 23:45 - How Much of a Rocket is Additive? Additive plays a growing—but complementary—role in rocket manufacturing. 26:30 - Additive in Satellites, Space, and In-Space Manufacturing Additive is key to building satellites, landers, and lunar systems. 32:00 - Lunar Regolith, Moon Dust, and Asteroid Mining NASA explores using Moon dust and asteroids for future construction. 36:50 - Learning from Failure: Engine...","thumbnail_url":"https://img.transistorcdn.com/27ZYLdyZ8MHWZlxUWh87sIQyB5ttPhwcP3_CmUBDsv0/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzE2NDk0LzE3MDU5/NDgwMjItYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
