Suman Das - Co-Founder, President and CEO
Dr. Suman Das is DDM Systems' Founder, President and Chief Executive Officer. He is the Director of the Direct Digital Manufacturing Laboratory and Morris M. Bryan, Jr. Chair in Mechanical Engineering for Advanced Manufacturing Systems at the Georgia Institute of Technology. He is an internationally recognized researcher and innovator in the fields of direct digital manufacturing, rapid prototyping, and large-area micro- and nano-structure additive manufacturing. Dr. Das has pioneered additive manufacturing applications and inventions for over two decades. During the decade of the 1990s, he was one among the early team of graduate student researchers in the Laboratory for Freeform Fabrication at the University of Texas, where Selective Laser Sintering (SLS) was invented. He remains the first researcher to demonstrate metallurgically high quality parts by SLS and laser melting. His deep SLS and laser sintering expertise and patents have made DDM System’s development of exclusive Large Area Maskless Photopolymerization (LAMP) and Scanning Laser Epitaxy (SLE) technologies possible. His current research focuses on advanced manufacturing, materials science, and computational modeling covering all material classes and length scales for applications in the aerospace propulsion, biomedical, energy and nanotechnology sectors. Dr. Das received his Bachelors in Mechanical Engineering from the Indian Institute of Technology in Madras, and both his Masters and Doctorate in Mechanical Engineering from The University of Texas at Austin. Prior to joining the Georgia Institute of Technology in 2007, Dr. Das was an Associate Professor at the University of Michigan-Ann Arbor where he directed the Solid Freeform Fabrication Laboratory. His contributions have been recognized through numerous awards including the University of Texas Outstanding Dissertation Award, the National Science Foundation Faculty Early Career Development Award, the Society of Manufacturing Engineers Outstanding Young Manufacturing Engineer Award, and the University of Texas Mechanical Engineering Department Distinguished Alumnus Award.
John W. Halloran - Co-Founder
Professor John Halloran has been active in 3D Printing of ceramics since he joined the University of Michigan two decades ago. Dr. Halloran invented the ceramic photopolymerization methods used for ceramic stereolithography that have been further developed for DDM’s exclusive LAMP technology. He has been developing these methods for digital manufacturing of airfoils since 1998. Prior to joining Michigan, he was a Program Manager in Advanced Ceramics CPS Technologies and the Vice President of Technology for CPS Superconductors, both part of the MIT spin-off Ceramic Process Systems (CPS), founded by Clayton Christensen and Kent Bowen in 1984 (before Bowen and Christensen joined the faculty of the Harvard Business School). At the University of Michigan, Dr. Halloran has invented several ceramic 3DP methods and other advanced manufacturing methods. He also co-founded Adaptive Materials, Inc., a spin-out from his laboratory, which invented a unique portable fuel cell technology. He sold his interest in Adaptive Materials when it was acquired by Ultra Electronics in 2011. Dr. Halloran previously served as the Chair of the Materials Science and Engineering Department at Michigan and recently retired as the Alfred White Collegiate Professor.
