题目：Additive Manufacturing of Bio-inspired Structures via Nanocomposite 3D Printing
Dr. Yong Chen is an associate professor of Industrial and Systems Engineering and Aerospace and
Mechanical Engineering and the Director of Daniel J. Epstein Institute at the University of Southern California (USC). He received his Ph.D. degree from Georgia Institute of Technology in 2001. Prior to joining USC, he was a senior Research and Development engineer in 3D Systems Inc, the pioneer in 3D Printing industry. Dr. Chen's research focuses on additive manufacturing (3D printing) in micro- and meso- scales. He received multiple Best/Outstanding Paper Awards in major design and manufacturing journals and conferences. Other major awards he received include the National Science Foundation Faculty Early Career Development (CAREER) Award and the Outstanding Young Manufacturing Engineer Award from the Society of Manufacturing Engineers (SME). Dr. Chen is a Fellow of American Society of Mechanical Engineers (ASME). He was the conference chair of the 2017 International Manufacturing Research Conference.
Many natural structures out-perform the conventional synthetic counterparts due to the specially evolved multi-scale and multi-material architectures. Such complex yet beautiful designs in nature are far beyond the fabrication capability of current 3D printing systems. This talk will report our recent work on developing new multi-scale and multi-material additive manufacturing processes to fabricate bio-inspired structures including (1) the Bouligand structure to create highly impact resistant architectures, and (2) the eggbeater structure to create superhydrophobic structures with petal effect. Some promising applications will also be demonstrated and discussed. The talk will conclude with remarks on future 3D printing developments.
