Manufacturing of personalized prosthetic leg using solid modeling and 3d printing

Abstract

After surgical amputation, the availability of a prosthetic device with correct dimensional measurements for the amputee limb is a general problem faced by several patients annually due to varying body sizes and dimensions of every individual. The prosthetic leg is generally manufactured in preferred sizes through machining of materials giving rise to several problems like long time taken to manufacture; unavailability of prosthetic leg to cater specific individual dimension, large geographic/regional distances having prosthetics and lack of infrastructure to manufacture such a device within a short period with high accuracy and dimensions. etc. This paper introduces a novel technique of an alternative approach for the development of prosthetic limbs on a Solid-works Model and then 3-D printing of the prostheses and casting it afterwards that allows the design of prostheses with required body dimensions of the individual, within a short span of time and with high accuracy.
