A masters student in product development at the School of Engineering at Lund University, Sweden, Emelie Strömshed,has developed a step-by-step process to combine prosthetic arm socket computer-aided design (CAD) data with 3D scan data of a patient’s residual limbs to create perfectly fitting 3D-printed prosthetic arm sockets.

The process she developed is intended to function as a guide for a prosthetic technician without requiring advanced CAD skills. The project aims to offer a viable alternative to the often time-consuming and manual labor-intensive conventional manufacturing method, as well as to provide amputee patients with perfectly fitted prosthetic sockets.

In addition, the process allows for the socket to be adapted to the use of both passive and active myoelectric prostheses.
