Overview

The building blocks of prosthetics come in many materials, shapes, and sizes. To create lightweight yet sturdy prosthetics, we explore 3D printing in plastic, carbon fiber, steel, and titanium. In addition, we investigate different methods of actuation such as miniature 3D printed gearboxes for fingers and twisted coil polymers. While some of these parts may look like something out of Star Wars, these are more than just computer-generated images. These prosthetics are real and they work for real people.
