Abstract
Additive manufacturing is a widely used technology in several areas allowing the manufacture of parts with different geometric shapes and a fast production. Within this context and the given relevance of the subject, the aim of the present study is on the execution of the open-source mechanical hand prosthesis (OS), called Partial Hand Prosthesis (PHP), and the manufacture of another distinct model of an OS device called the Prosthetic Hand (PH), using the additive manufacturing technique through three-dimensional printing technology, and the prosthetic models are obtained through files from the Thingiverse website. The PHP prosthesis was submitted to mechanical tests, through simulations using Finite Element (EF) software, in order to evaluate the mechanical properties of the model used. The PH model was printed and built with certain print parameters. The present work presents the mechanical feasibility study of the PHP device, as a result: good mechanical performance in a scenario of compression of a solid object; simulation of static forces and reaction forces at the extremities of the prosthesis fingers. For the PH device the results has shown that the file of the prosthetic model, together with the fast prototyping process, presented good dimensional accuracy; relative difficulty in its mountability; fast construction and low cost production.
