Knack - A 3D Printed Upper Limb Prosthesis

Bronze
2022

Knack is an upper limb prosthesis developed to provide economically disadvantaged amputees with an improved ergonomic and functional prosthesis experience. It uses 3D scanning to achieve a perfect fit by collecting a high-resolution model of the amputee’s body. The 3D printing method allows for a lightweight prosthesis with high dexterity, leveraging the flexibility of the additive process to create customized components with a personalized aesthetic. The prosthetic hand mechanism was simplified by using elastic thermoplastic polyurethane hinge springs at all the joints. Kinetic movement comes from a hybrid system with body-powered arm actuation and a motorized hand unit.
