Complex Shape Design for Direct Digital Manufacturing

ISE 650 SEMINAR IN INDUSTRIAL ENGINEERING: "Complex Shape Design for Direct Digital Manufacturing"Guest Speaker: Dr. Yong ChenAssistant Professor, USC Daniel J. Epstein Department of Industrial and Systems EngineeringABSTRACT: Layer-based Solid Freeform Fabrication (SFF) is a direct manufacturing process that can fabricate complicated geometries cost-effectively. Recent advances in material, process and machine development have enabled the SFF processes to evolve from prototype usage to direct product manufacturing. Direct Digital Manufacturing (DDM) based on the SFF processes provides tremendous design freedom including the possibility of developing revolutionary new designs by utilizing complex geometry. However, a much higher degree of geometric complexity in design also poses significant challenges in modeling, analyzing, synthesizing, and optimizing shapes to meet the specified requirements. The talk provides an introduction of DDM and the related design opportunities and challenges. Some researches on DDM and design for DDM will also be highlighted including using complex shapes to achieve heterogeneous material properties and multi-functionality in a product component. THURSDAY, OCTOBER 30, 2008, 12:00-1:00 PM, GER 309BIO: Dr. Chen is an Assistant Professor in the Industrial and Systems Engineering department at USC. His research interests are in the areas of computer-aided design and manufacturing; especially computer-aided design tools for additive manufacturing; process development for Rapid Prototyping and Tooling; and geometric reasoning in product design, analysis and manufacturing. He received his Ph.D. in Mechanical Engineering from the Georgia Institute of Technology in 2001. Prior to joining the University of Southern California in 2006, he was a senior Research and Development engineer at 3D Systems, Inc. (Valencia, CA) for five years, focusing on the development of layer-based manufacturing systems and 3D printers.
