Dr. Starr has conducted research in additive manufacturing and 3D printing technology for nearly 20 years. Over the past several years Dr. Starr’s investigation of mechanical performance of metal alloys fabricated by LS has produced some of the only openly-available data on fatigue performance of these materials. His prior work includes evaluation of stereolithography (SLA) tooling for ceramic injection molding, use of powder delivery laser deposition (LD) for combinatorial alloy development, and powder bed laser sintering (LS) for additive manufacturing of plastic and metal parts. His research aims to create better understanding of the laser sintering process for both metals and polymers and how process parameters affect mechanical performance. His work with polymer LS led to a new correlation among process parameters that better relates to mechanical performance. This “energy-melt-ratio” is uniquely suited to investigation of new and higher temperature polymers.
