报告人:Dr. Yong ChenUniversity of Southern California

 

报告简介:

Many natural structures out-perform conventional synthetic counterparts due to the specially evolved multi-scale and multi-material architectures. However, the majority of current 3D printing systems are designed to fabricate parts using a single material in a single scale mainly for structural purpose. Such complex yet beautiful designs existing in natural structures are far beyond the fabrication capability of current 3D printing systems. This talk will report our recent work on developing new multi-material and multi-scale additive manufacturing processes to fabricate bio-inspired structures including (1) the lobster and nacre shell structures to create highly impact resistant architectures, and (2) the micro-scale surface textures of the Salvinia Molesta leaves and cactus to achieve hydrodynamic properties. After a brief overview of current 3D printing technology, an electrically assisted additive manufacturing (AM) approach to fabricate complex reinforcement architectures will be presented. The fabricated structures show significantly enhanced impact resistance with self-sensing capability. Another additive manufacturing process named Immersed Surface Accumulation to fabricate complex micro-scale textures on an object surface will be presented. Such an AM process enables one to reproduce biomimetic functional surfaces to achieve interesting hydrodynamic properties such as hydrophobicity and petal effect. Some promising applications enabled by the 3D-printed structures will also be discussed. The talk will conclude with remarks and thoughts on future 3D printing developments and potential opportunities for product designers and manufacturing engineers.

报告人简介:


Dr. Yong Chen is a 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 obtained the Ph.D. degree in Mechanical Engineering from Georgia Institute of Technology in 2001, and was a Senior Research and Development Engineer in 3D Systems Inc. for five years. Dr. Chen’s research focuses on additive manufacturing (3D printing) in micro- and meso- scales. He has published more than 140 publications in refereed journals and conferences as well as 12 issued and pending U.S. patents. His work has been recognized by over ten Best/Outstanding Paper Awards in major design and manufacturing journals and conferences including SME NAMRC Outstanding Paper Award, ASME MSEC Best Paper Award, ASME CIE Best Paper Award, SFF Symposium Outstanding Paper, and RPJ Outstanding Paper Award. Other major awards he received include the NSF Faculty Early Career Development (CAREER) Award, the Outstanding Young Manufacturing Engineer Award from the Society of Manufacturing Engineers, and the invitations to the National Academy of Engineering Frontiers of Engineering Symposiums. Dr. Chen is a Fellow of the American Society of Mechanical Engineers (ASME). He has served as conference/program chairs as well as keynote speakers in several international conferences. He is an associate editor for the ASME JCISE, Computer-aided Design, and IIE Transaction – Design and Manufacturing Focus, and serves on the editorial boards of Virtual and Physical prototyping, Journal of Intelligent Manufacturing, and International Journal of Precision Engineering and Manufacturing.
