报告人简介

Albert Shih is Professor in Mechanical Engineering, Biomedical Engineering, and Institute of Gerontology at the University of Michigan.  He was a manufacturing process development engineer at Cummins (1991-1998) and an Associate Professor at NC State University Mechanical and Aerospace Engineering (1998-2002).  He has been a faculty at the University of Michigan since 2003.  In 2017, he was the Assistant Director of Education and Workforce in the Advanced Manufacturing National Program Office (AMNPO) at Gaithersburg, Maryland.  Dr. Shih’s research area is 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 10 US patents, a textbook in Analysis of Machining and Machine Tools, and authored or co-authored over 200 archival journal papers, 110 conference papers in manufacturing and biomedical sciences.  Dr. Shih is the recipient the Fulbright Scholar, SME Taylor Medal in manufacturing research, ASME Milton Shaw Manufacturing Research Medal and Blackall Machine Tool and Gage Award, 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).  Dr. Shih is Fellow of both ASME and SME and associate member of CIRP.

报告简介

This talk provides an overview of the cyber-based design and 3D-printing (3DP) for custom assistive devices at the University of Michigan Orthotics and Prosthetics Center (UMOPC). Assistive devices, such as orthoses and prostheses (O&P) and masks for continuous positive airway pressure (CPAP), are critical for people to maintain their function, independent living and basic quality of life.  Custom assistive devices have personalized fit, better comfort, and superior efficacy in treatment.  This talk outlines our on-going journey to develop a design and manufacturing system at UMOPC for a wide variety of custom assistive devices. The manufacturing system has the digital scanning, cyber-based software for design, and material extrusion (MEX) for AM that aim to improve patient care. Key elements of this manufacturing system presented in this talk include the: 1) 3D scanning to identify the shape, 2) computer aided design for clinicians to modify the shape, 3) cyber- and model-based design, 4) wavy structure tool path planning for O&P, 5) MEX 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. An example of custom ankle-foot orthosis (AFO) with fabrication time that enables one-day visit for patient care is presented.
