Developing a Scalable, Low-Cost Prosthetic Device for Below-Knee Amputations Public

The goal of this project was to design a low cost and easily reproducible prosthesis that has the ability to mimic a person’s gait cycle. The overall prosthesis design was broken into three components: socket, pylon, and foot. The designs of each component were modeled similarly to pre-existing products, but were made easier to manufacture. 3D printing was the main manufacturing technique for the three components; varying machines and materials were used based on necessary material characteristics. A four-bar linkage system was developed to evaluate the prosthesis’s ability to mimic the locomotion of a person’s gait cycle. Ultimately, parametrized CAD models were developed to allow regeneration of prosthesis based on user measurements.
