讲座内容简介

Many natural structures out-perform the conventional synthetic counterparts due to thespecially 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-scale and multi-material additive manufacturing processes to fabricate bio-inspired structures including (1)the Bouligand structure in natural creatures to create highly impact resistant architectures, and (2)the eggbeater structure of the SalviniaMolesta leaves to create superhydrophobic structures.After a brief overview of current 3D printing technology, anelectrically assistedadditive manufacturing (AM) approach to fabricate complex reinforcement architectures will be presented.Thefabricated structuresshowthree times enhanced impact resistance with Bouligand-typeorientationcompared with random orientation. Anotheradditive manufacturing processnamedImmersed Surface Accumulationtofabricatecomplex micro-scalestructureson an object surfacewill also be presented. Such AM process enables one to reproduce biomimetic functional surfacesto achieveinteresting propertiessuch ashydrophobilicity and petal effect. Both AM processes are based on nanocomposite by mixing multi-walled CarbonNanotubeswith photocurable resins. Some promising applications enabled by the 3D-printed structures will also be demonstrated and discussed. The talk will conclude with remarks and thoughts on future 3D printing developments and potential opportunities for product designers and manufacturing engineers.

主讲人简介

Dr. Yong Chen is an associate professor in the Department of Industrial and Systems Engineering and Department of Aerospace and Mechanical Engineering (courtesy) at theUniversity of Southern California(USC). He received his Ph.D. degree in Mechanical Engineering fromGeorgia Institute of Technologyin 2001. Prior to joining USC in 2006, he was a senior Research and Development (R&D) engineer in3D Systems Inc, the pioneer in 3D Printing industry. Dr. Chen’s research focuses on additive manufacturing (3D printing) in micro- and meso- scales, especially modeling, analyzing, synthesizing, and optimizing digital design and manufacturing. Dr. Chen has published more than 100 publications in refereed journals and conferences. Among them,he received over 10Best/Outstanding Paper Awardsin major design and manufacturing journals and conferences.Other major awards he received include the National Science FoundationFaculty Early Career Development (CAREER) Award, and theOutstanding Young Manufacturing Engineer Awardfrom the Society of Manufacturing Engineers (SME). He was cited as one of the top young engineers (ages of 30-45) in USA through the invitation to the National Academy of Engineering (NAE)Frontiers of Engineering Symposiumin 2009 and 2013, and chaired Advanced Manufacturing session inChina-American Frontiers of Engineering Symposiumin 2015. Currently he is serving in the editorial boards ofComputer-aided Design,ASME Journal of Computers and Information in Engineering, andInternational Journal of Precision Engineering and Manufacturing. He has served as conference/program chairs as well as keynote speakers in several international conferences, including the Conference Chair of the 2017 International Manufacturing Research Conference (NAMRC/MSEC/ICM&P) held in Los Angeles, California in June 2017.
