Abstract— A lot of research is happening in medical field in the area of prosthesis with a aim to reduce the cost and at the same time, the artificial limb being effective. The current work concentrates on the area of prosthetic hand. Most of the prosthetic arms currently available are motor driven and costly. There are non-powered prosthetic hand also but involve the use of elastic band on solid fingers which make the arms heavy. The current work is aimed at overcoming these difficulties by the use of EPE foamed fingers which are driven actuated by a tendon by the gesture of palm while the foam provides the necessary spring back. CAD models are prepared using proe while 3D printing is used for fabricating most of the arm. EPE is used as foam material while PLA and Acrylic are used for outer structure.
Keywords— 3D printing, EPE foamed finger, PLA, prosthetic hand, tendon driven.
