Title of the report ：3D Printing：From Rapid Prototyping to Rapid Manufacturing
Place：Room 402, State Key Laboratory of CAD & CG, Library and Information Center Building B, Zhejiang University Zijin’gang Campus
Reporter：Dr. Yong Chen
Abstract：The advent of 3D printing/additive manufacturing and its use in rapid prototyping has drastically changed the design and manufacturing landscape by enabling companies to prototypeand produce products faster and cheaper. With the price of these technologies dramatically dropping in recent years, their accessibility is on the increase. However, significant challenges remain to be addressed in the future 3D printing development in order to achieve direct digital manufacturing for future engineering systems. This talk will provide an overview of 3D printing technology and discuss some of its benefits including unlimited geometric capability,heterogeneous material property, etc. Some limitations and challenges of the technology will also be discussed with some of our research work for addressing them. The talk will conclude with a few remarks on future opportunities and potential applications.
Short-Bio：Dr. Yong Chen is an associate professor in Epstein Department of Industrial and Systems Engineering at the University of Southern California (USC). He received his Ph.D. degree in Mechanical Engineering from the Georgia Institute of Technology in 2001 and his B.S. degree in Mechanical Engineering from Zhejiang University in 1993. Prior to joining the USC in 2006, he was a senior Research and Development (R&D) engineer at 3D Systems Inc, the pioneer and world leader in digital manufacturing systems. Over the five years at 3D Systems, he participated in various R&D projects related to the development of Stereolithography Apparatus (SLA) and Selective Laser Sintering (SLS) systems, and 3D printers including multi-jet printing (InVision) and V-Flash desktop modeler.
Dr. Chen’s research focuses on direct digital manufacturing (DDM) in micro- and mesoscales,especially modeling, analyzing, synthesizing, and optimizing DDM processes, and developing related computer-aided design methods and tools. Dr. Chen has published more than 75 publications in refereed journals and conferences. Among them, he received four Best Paper Awards in the ASME 25th, 28th, 31st, and 32nd annual Computers and Information in Engineering (CIE) conferences in 2005, 2008, 2011, and 2012 respectively; a Best Paper Award in the 2012 ASME annual Manufacturing Science and Engineering Conference (MSEC); a Outstanding Paper Award in the SME 39th North American Manufacturing Research Conference (NAMRC) in 2011, and a Outstanding Paper Award in the 21th International Solid Freeform Fabrication (SFF) symposium in 2010. He also received an annual Outstanding Paper Award of the year of 2011 from a major DDM journal – Rapid Prototyping Journal. Other major awards he received include the National Science Foundation (NSF) Faculty Early Career Development (CAREER) Award in 2012, an Outstanding Young Manufacturing Engineer Award from the Society of Manufacturing Engineers in 2008, and a Leadership and Service Award from the ASME CIE division in 2010. He was cited as one of the top engineers between the ages of 30-45 in USA through the invitation to the Frontiers of Engineering Symposium of the National Academy of Engineering (NAE) in 2009 and 2013.At the USC, Dr. Chen teaches design and manufacturing related courses to undergraduate and graduate students. He also serves as an academic advisor to the undergraduate Fab lab at the USC. Dr. Chen is an active member of the American Society of Mechanical Engineers (ASME),the Society of Manufacturing Engineers (SME) and the Institute of Industrial Engineers (IIE).
