SFU Researchers Revolutionize Prosthetic Design
Researchers at Simon Fraser University (SFU) have developed a transformative 3D printed socket design that is fully customizable for prosthetics. This innovation marks a significant shift in the prosthetics industry by focusing on personalization and comfort.
Revolutionary 3D Printed Prosthetic Socket Design
The new limb socket interface integrates AI software and advanced pressure mapping technology to create lightweight, breathable, and more comfortable prosthetic devices. Woo Soo Kim, a professor at SFU’s School of Mechatronic Systems Engineering, emphasizes the importance of capturing unique pressure and force distribution data from patients to enhance comfort and fit.
Key Findings from the Study
- The innovation showed a 1,600% increase in energy absorption when standing compared to traditional solid infills.
- When walking, the energy absorption increased by 1,290% over conventional designs.
Traditional fittings rely on casts or digital scans, which may not account for individual pressure points. This new method uses a silicone liner with a miniature 3D-printed pressure sensing mat made of origami sensors to gather precise data during common activities such as standing and walking.
Customized Design and Benefits
The researchers utilized custom AI software to convert pressure data into a personalized socket design featuring a unique lattice structure, reminiscent of natural patterns like honeycombs. This design not only enhances comfort but also reduces potential health complications such as ulcers, pain, and musculoskeletal issues by improving energy absorption.
Collaboration with Clinical Partners
The project involved collaboration with Hodgson Group Orthotics and Prosthetics to merge clinical practice with emerging technology. According to Loren Schubert, a prosthetist at Hodgson Group, this data-driven design approach significantly improves prosthetic fit and comfort. Carl Ganzert, an orthotist, noted that innovative and cost-effective solutions can reshape the future of prosthetic devices, making them more accessible and beneficial to users.
Publication and Support
The study titled “Streamlined custom manufacturing for optimized 3D printed prostheses through 3D pressure mapping” was published in the journal Biosensors and Bioelectronics on June 16, 2026. The research was funded by the Natural Sciences and Engineering Research Council of Canada (NSERC) and the Hodgson Orthopedic Group.
Through these advancements, SFU researchers aim to enhance the quality of life for prosthetics users and ensure access to comfortable, personalized devices for all individuals in need.
