Abstract

Virtual prototyping and additive manufacturing are critical to rapid product development and realization. This seminar will present the recent and ongoing research of the

speaker in these two interconnected areas. Our virtual prototyping research includes development of geometric modeling techniques that comprise swept-volume representation

using a sweep-differential equation approach, and surface reconstruction based on dexel modeling and tri-dexel modeling. The results of this research have been integrated with

haptics and sound modeling for purpose of multi-modal rendering, and they have been applied to virtual sculpting, virtual bone surgery, and other virtual prototyping applications.

Also presented is low-cost motion capture and application to automated real-time CAD model based simulation and analysis. Our additive manufacturing research includes the rapid freeze

prototyping (RFP) process, the freeze-form extrusion fabrication (FEF) process, and the selective laser sintering (SLS) process. The RFP process builds an ice part by depositing and

freezing water droplets on demand. The FEF process extrudes one or multiple aqueous pastes to fabricate parts from monolithic or functionally gradient materials. The SLS process

fabricates a part by selectively sintering particles in a power bed. Our research for the various processes includes theoretical modeling and analysis, finite element simulation, process

planning and control, and experimental testing. Also included in the research are post-processing and investigating the fabricated parts for aerospace, biomedical, and energy applications.

Speaker Biosketch:

Dr. Ming C. Leu is the Keith and Pat Bailey Missouri Distinguished Professor in the Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology.

He also holds the leadership positions as the Director of Center for Aerospace Manufacturing Technologies and the Director of Intelligent Systems Center at Missouri S&T. Before joining

Missouri S&T, he was a Program Director for Manufacturing Processes and Equipment at the National Science Foundation, 1996-1999. For the NSF appointment he was on leave from the

New Jersey Institute of Technology, where he had been the State Chair Professor in Manufacturing Productivity since he joined NJIT in 1987. Before that he was on the faculty of the

School of Mechanical and Aerospace Engineering, Cornell University. Dr. Leu obtained his Ph.D. degree in 1981 from the University of California at Berkeley, his M.S. degree in 1977

from the Pennsylvania State University, and his B.S. degree in 1972 from the National Taiwan University, all in mechanical engineering. Dr. Leu’s research interests include CAD/CAM,

geometric modeling, virtual prototyping, rapid prototyping, and additive manufacturing. He has published over 320 papers in refereed journals and conference proceedings, 8 book chapters,

and 4 U.S. patents. Through his research activities he has served as the principal advisor to 23 Ph.D. and over 60 M.S. graduates, as well as 15 post-docs. Dr. Leu has received several

professional awards, including the ISFA Hideo Hanafusa Outstanding Investigator Award (2008), MCASTA Outstanding Scholar Award (2006), ASME Distinguished Service Award (2004),

Missouri S&T AMAE Faculty Excellence Award (2001 & 2004), NJIT Harlan J. Perlis Research Award (1993), NSF Presidential Young Investigator Award (1985), SAE Ralph R. Teetor

Education Award (1985), and FPRS Wood Paper Award (1981), and was on the NJIT team to receive the CASA/SME University Lead Award (1994). He was elected to ASME Fellow in 1993

and to CIRP Fellow in 2008, and is a member of the Sigma Xi, Tau Beta Pi, and Phi Kappa Phi honor societies. Dr. Leu has been very active in professional service activities.  He organized and

chaired the 2012 International Symposium on Flexible Automation and the 2006 NSF Design, Service and Manufacturing Research Conference. He was the General Chair of 2006 ASME

International Mechanical Engineering Conference and was the Technical Program Chair of this conference in 2005. Additionally, he organized and edited the proceedings of eight other symposia i

n the manufacturing field. He was the ASME Vice President for Manufacturing, 1999-2002, and served on the Executive Committee of ASME’s Manufacturing Engineering Division, 1986-1990.
