This seminar presents a cyber-based design and additive manufacturing (AM) for custom orthoses. 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 have personalized fit, better comfort, and superior efficacy in treatment than pre-fabricated ones for users.  A cyber-physical service system (CPSS) has been developed for the University of Michigan Orthotic and Prosthetic Center (UMOPC).  CPSS has the digital scanning, cyber-design center, and fused deposition modeling (FDM) for AM that aim to improve the quality of patient care and service of custom orthoses.  This CPSS will be implemented at UMOPC for custom ankle-foot orthosis (AFO).  The fabrication time and material cost for 3D-printing are critical to provide advantages over the conventional plaster molding for fabrication.  This system targets to achieve the one-day visit for patients who need AFO.  Key elements of CPSS presented in this talk include the: 1) 3D scanning of the foot and leg, 2) computer aided design for clinicians, 3) cyber- and model-based design, 4) wavy structure tool path planning for AFO, 5) FDM for hard structure and soft silicone for wearable assistive devices, 6) quality control using the nano-CT technology, and 7) inertia measurement unit (IMU) for gait analysis, evaluation, and monitoring of users.  Expansion of CPSS for prosthetic socket, foot orthoses, and other assistive devices are elaborated.

Albert Shih is Professor in Mechanical Engineering, Biomedical Engineering, and Integrative Systems + Design (ISD) at University of Michigan and Assistant Director of Technology, Advanced Manufacturing National Program Office (AMNPO). He was a manufacturing process development engineer from 1991 to 1998 at Cummins.  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, 100 conference papers in manufacturing and biomedical sciences.  Dr. Shih is the recipient of many awards including the Fulbright Scholar, ASME Milton Shaw Manufacturing Research Medal, Society of Automotive Engineers Ralph 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.
