Neal Polley, PhD
Additive Manufacturing Materials Engineer
Neal Polley is an Additive Manufacturing Materials Engineer at ASTM International’s Additive Manufacturing Center of Excellence (AM CoE), bringing over 25 years of experience in additive manufacturing, metallurgy, and advanced materials engineering. A highly accomplished senior research engineer, Neal’s technical leadership has guided cross-functional teams in developing, validating, and standardizing AM processes in alignment with AS9100, ASTM, and SAE standards.
Neal began his career as a tool maker and mechanical engineer. He has held senior engineering positions at GKN Aerospace and the UK’s Atomic Weapons Establishment (AWE), where he led R&D initiatives in additive manufacturing, casting, and heat treatment. Throughout his career, Neal played a key role in advancing metal additive manufacturing technologies, particularly Laser Powder Bed Fusion (LPBF), within the aerospace and defense sectors.
Neal holds a Bachelor of Engineering and a Ph.D. in Metallurgy from Brunel University, where his research focused on developing reinforced aluminum composites. A recognized industry contributor, he serves as a voting member on both ASTM Committee F42 on Additive Manufacturing Technologies and SAE’s AMS Additive Manufacturing Metals Committee. As a Fellow of the Institute of Materials, Minerals and Mining (FIMMM) and a Chartered Engineer (CEng), Neal continues to advance the science and application of additive manufacturing on a global scale.
Neal’s work has been featured in major industry publications, including IndustryWeek, Aerospace Manufacturing and Design, and Today’s Medical Developments, where he advocates for greater standardization and innovation in AM.
