Design of Lower Prosthetic Limb Using Additive Manufacturing Processes

Abstract

This paper presents an approach for designing a prosthetic limb using SolidWorks. The process of stereolithography helped manufacture the prosthetic limb due to the flexibility in the provided parameters. The designed leg weighs 4kg approx. The entire weight acts on the sole of the leg. The sole again underwent a SolidWorks simulation with the application of a 1200N load. The preferred material-TPU-was selected after considering all the factors. The manuscript proceeds with a financial analysis to get a price estimate for the manufacturing of each part of the limb, which is a crucial factor.
