2A2-I10 Two Types of Electric Prostheses Created with a 3D Printer

Abstract

Though commercial prostheses are useful, they have issues in operability, appearance, cost, weight, and maintenance. To solve these issues, we are developing two types of electric prostheses created with a 3D printer. Finch is an electric prosthesis which has opposed three fingers specialized in daily work. Rehand is an electric prosthesis which has an appearance similar to a cosmetic prosthesis. Both prostheses have a common component which consists a supporter socket and an operating system using a distance sensor. This paper describes these prostheses, and discusses the merit and demerit of using a 3D printer in developing prostheses.
