SUTD, together with Tan Tock Seng Hospital, developed a novel 3D printed non-metallic self-locking prosthetic arm for a patient with a forequarter amputation – it is more comfortable, flexible and 20% cheaper than a conventional prosthesis.

The schematic representation of the various stages involved in the user-centered, iterative process of prosthesis design.

Upper limb forequarter amputations which involve the removal of the entire arm and scapula require highly customised prosthetic devices that are expensive but yet, usually underutilised due to their high maintenance and low comfort levels. At the same time, while cosmetic prostheses – artificial limbs which provide patients the appearance of a pre-amputated body part – have a higher rate of continuous use, they have limitations in functional use.
