Abstract
The use of mechanical prostheses for returning, as close to reality as possible, the motor function of upper limbs in people with hand or arm amputation is becoming increasingly common, especially after the advent of additive manufacturing technology, which enables the manufacture of various part geometries in a fast and relatively inexpensive production system, besides providing easy customization and personalization of the models produced. Several files for the development and construction of these mechanical hand prostheses are available and can be easily accessed on Open Source platform sites worldwide, such as the Thingiverse and e-NABLE platforms, which operate on the basis of a voluntary global community to provide files and project documentation focused on three-dimensional printing. The purpose of this paper is to select a hand prosthesis on the Open Source sharing site (Thingiverse) for a mechanical feasibility study by developing a temperature, stress and displacement analysis, finding stress, displacement and temperature concentration points on the surface of the device when dynamic and static loads are applied, in order to verify the behavior and mechanical responses using finite element method (FEM) analysis software.
