Researchers at Simon Fraser University (SFU) are set to make significant advancements in the prosthetics field with their innovative 3D printed socket design. This revolutionary approach focuses on creating fully customizable prosthetic sockets that enhance comfort and usability for patients.
Transformative 3D Printed Prosthetics
The new prosthetic design amalgamates sophisticated pressure mapping technology with artificial intelligence (AI) software. This combination results in lighter, more breathable prosthetics tailored to individual needs. According to Woo Soo Kim, a professor at SFU’s School of Mechatronic Systems Engineering, this approach utilizes unique pressure and force distribution data to optimize socket design.
Key Findings from the Study
- 3D printed limb sockets with a lattice infill exhibited 1,600% more energy absorption when standing.
- Energy absorption increased by 1,290% when walking in comparison to traditional solid infills.
Traditional methods for making prosthetic sockets rely heavily on casts or digital scans, which do not take into account the unique pressure points of each user. The SFU team’s innovative approach embeds miniature 3D-printed pressure sensors within a silicone liner. This allows for accurate measurement of pressure and force during various activities, including standing and walking on flat surfaces.
AI-Driven Customization
The researchers developed custom AI software that translates the collected pressure mapping data into a personalized socket design. They used a lattice structure, commonly found in nature, to enhance the socket’s performance. This design not only improves comfort but also helps in minimizing health risks typically associated with prosthetic wear, such as ulcers and instability.
Collaboration with Hodgson Group
To link clinical practices with cutting-edge technology, Hodgson Group Orthotics and Prosthetics collaborated with SFU. Their involvement underlines the potential impact of data-driven design on prosthetic fit and long-term skin health.
Loren Schubert, a prosthetist at Hodgson Group, remarked on the importance of this research in enhancing the quality of life for patients with limb loss. Carl Ganzert, an orthotist in the group, echoed this sentiment, emphasizing that these innovations could make prosthetic solutions more accessible and affordable.
Future Prospects
As the 3D printed socket technology becomes more refined, the goal is to support local prosthetic companies in meeting the needs of their clients. This initiative aims to ensure that personalized and comfortable prosthetic devices are available to all who require them.
The study, which highlights the groundbreaking potential of this approach, was published in the journal Biosensors and Bioelectronics on June 16, 2026. It reflects a significant step forward in the quest for improved prosthetic technology.
