Abstract

The summary of this project is to produce the catalogue of leg sizing for a set category of human body by taking the dimension of weight and shoe size. Then, this is the product of innovation to improve the current use leg cast that can easily be made by using 3D Printing. The design starts with reverse engineering using 3D scanner. There are a few problems of the current use leg cast which is heavy and this can lead to burdening the patients while moving. Then, the current use leg cast does not have any air flow through out it and this can affect the leg to contain more heat and less comfortable for the wearer. The current use cast is also not waterproof. This project focuses on the temperature result data of the inside of the both cast while wearing it. And the temperature difference between current cast and new immobilization cast is a lot. Produce the catalogue of leg sizing depending on the weight and the shoe size of people. The dimension measured is based on the anthropometry data. Lastly, running analysis of design part to obtain the maximum stress acting on the new design when putting a 1000 N of force. The analysis is done by using solidthinking. The result proves that the cast design with nylon as its material is strong enough to withstand load a high as 1000 N or approximately 100 kilograms
