3D printed bionic prosthetic hands

Abstract

This article deals with upper limb prosthetic made by 3D printing technology. For tests and analysis the number of open-source bionic hands (eNable and exiii's HACKberry projects) were chosen. These hands represent low cost solution of conventional or myolectric prosthesis. Our investigation was focused on three main parts: 3D printing using different 3D printers, technologies and materials; assembly with the use of commonly gettable fasteners and devices on Czech market; functionality testing under laboratory condition. In conclusion our results of these fields are summarized and possible improvements are outlined.
