Albert Shih is Professor in Mechanical Engineering, Biomedical Engineering, and Integrative Systems and Design (ISD) at the University of Michigan. He is the Associate Chair of ISD and Director of the Global Automotive and Manufacturing Engineering Program. He was a manufacturing process development engineer, specialized in advanced grinding, from 1991 to 1998, at Cummins Inc. Dr. Shih’s research area is design and manufacturing. He is a pioneer in biomedical manufacturing, the application of manufacturing technologies to advance the safety, quality, efficiency and speed of healthcare service and biomedical science. He has 9 US patents, a textbook in Machining and Machine Tools, and authored or co-authored over 180 archival journal papers, 90 conference papers in manufacturing and biomedical sciences. Dr. Shih is the Chair of Scientific Committee of the North American Manufacturing Research Institution of the Society of Manufacturing Engineers (NAMRI/SME). He is the recipient of many awards including the Fulbright Scholar, ASME Milton Shaw Manufacturing Research Medal, Society of Automotive Engineers Ralph R. Teetor Educational Award, and Best Paper awards in ASME International Manufacturing Science and Engineering Conference (MSEC), North American Manufacturing Research Conference (NAMRC), International Conference on Frontiers of Design and Manufacturing (ICFDM) and several other manufacturing and healthcare conferences. Dr. Shih is Fellow of both ASME and SME and associate member of CIRP. He received his B.S. and M.S. from National Cheng Kung University and Ph.D. from Purdue University.
报告摘要：
Advancements in additive manufacturing system that impacts the patient care of custom orthoses are presented. Orthoses, also known as braces, are assistive devices for structural support of the neuromuscular and musculoskeletal systems to help people with impairments to regain their mobility and independent living. Custom orthoses has personalized fit, better comfort, and superior efficacy in treatment than pre-fabricated ones for users. Unlike factory with engineers on-site, the digital design and manufacturing are challenges in the hospital setting. This talk presents a cyber-physical manufacturing system at the University of Michigan Orthotic and Prosthetic Center (UMOPC) with cloud-based design and additive manufacturing (AM) of the ankle-foot orthosis (AFO). The fabrication time and material cost for AM are critical to provide advantages over the conventional methods for fabrication. This system targets to achieve the one-day visit for stroke patients who need AFO. Key elements of the manufacturing system presented in this talk include the: (1) digital scanning of the foot and leg, (2) CAD software for process and exchange the surface and solid .STL files, (3) web-portal for clinician and design engineer, (4) wavy structure tool path planning for AFO, (5) fused deposition modeling (FDM) of carbon fiber in Nylon for hard structural and soft silicone for wearable assistive devices, and (6) inertia measurement unit (IMU) for gait analysis and monitoring of users. Measurement techniques for evaluation and quality control are presented. Expansion of this manufacturing system for prosthetic socket, foot orthoses, and other assistive devices are elaborated. Altogether, the cyber-physical service system (CPSS) features the one-day delivery, passive dynamics for personal needs, long-term monitoring using the IMU for custom assistive devices and demonstrate the potential societal impacts enabled by the virtual manufacturing of personalized products.
