Abstract

Ankle orthosis is external support and prevent the various foot and ankle injury. The purpose of this report is to design an ankle orthosis with 3D scanner and additive manufacturing process. The aims of this project is produce the ankle orthosis with improve functionality and comfortably to a user. This project focused to design and develop a prototype of ankle orthosis based on geometry of user’s foot shape. Mostly, the existing support device for ankle orthosis especially for users that suffers from severe injuries such as ankle sprain. Ankle Sprain is the most typical musculoskeletal injury for athletes. The function of ankle orthosis is adjusted for the appropriate size of user, size into shoes, comfortable, easy to wear. In addition, the cost required to produce an existing ankle support is quite expensive as they require more than one process machine and material to produce ankle orthosis. To finish the process development of the ankle orthosis there are several methods had been used for conducting this project. As starting, a preliminary survey was been conducted to get feedback from the user about the respondents were been choose for customize size concept than standard size for the ankle orthosis. Besides that, Analytical Hierarchy Process is used to select the best design requirement from three different concept design. After obtain the data, the Faro Scanner Freestyle 3D is used to scan the foot and convert it into the software Geomagic studio 10. Then, edit and check the foot data using Materialise Magic software. Meanwhile the ankle orthosis is drawn and edited by Meshmixer software. By using Solidwork software (FEA) for evaluate the stress analysis of the strength of new ankle orthosis. The filament of TPU was selected for fabricate ankle orthosis by using FDM machine. Lastly, the functional test was conducted based on human subject testing.
