Emelie Strömshed from School of Engineering at Lund University in Sweden, has developed a step-by-step process to combine prosthetic arm socket CAD data with 3D scan data of a patients residual limbs to create perfectly fitting 3D printed prosthetic arm sockets. This process is intended to guide prosthetist without requiring extensive experience in CAD and also allows socket to be adopted for passive and active myoelectric prostheses.
