ADDITIVE MANUFACTURING FOR ASSISTIVE TECHNOLOGY : Innovative Design for an Ankle Foot Orthosis

Sammanfattning: The following report presents a Master thesis project about a re-design of an ankle foot orthosis using additive manufacturing as the production method, conducted by a student in Spring 2020 as part of the Master’s programme Industrial Design at Jönköping University’s School of Engineering. Ankle foot orthoses are the most prescribed lower extremity orthoses worldwide and are worn in a visually obtrusive way making patients feel stigmatized for their disability. The social stigma makes it emotionally difficult for many users to wear an AFO frequently enough for proper rehabilitation. Despite its significance and wide spread use, its design has not changed for over 50 years. Traditional manufacturing methods are difficult to work with and make customization options very limited. By using digital additive manufacturing methods like 3D Scanning, 3D printing and computer simulations, it is possible to offer personalized looks for AFOs by implementing almost any custom pattern expressed in cut-outs on the AFO surface. That kind of perforation simultaneously solves the problem of bad perspiration and air flow. The freedom of graphical expression in those patterns invite the patient to participate in the design process themselves to create an ankle foot orthosis that is their own. That revolutionary twist on the manufacturing and design process empowers the user to take control over their disability to the furthest degree possible and returns the human right of self-determination and independence to them.
