Abstract
Additive manufacturing is a widely used technology in various fields, enabling the rapid production of parts with different shapes and geometric complexities. This study focuses on conducting a mechanical feasibility analysis of two open-source hand prostheses: the K1 Hand (KH) and the Raptor, using three-dimensional printing technology. The prosthetic models were obtained from online platforms such as e-NABLE and Thingiverse, which freely share open-source digital design files, including upper limb prosthetic models. The KH prosthesis will undergo mechanical testing through Finite Element Method (FEM) simulations to evaluate its mechanical properties. The Raptor model will be printed and constructed according to predetermined printing parameters. These prostheses aim to replace and meet the needs of individuals with permanent physical disabilities, serving essential functional and psychological purposes. In this context, the main objectives of this work are to assess the mechanical behavior of the KH prosthesis through FEM simulations, analyzing its mechanical performance in situations involving compression of solid objects, static force simulations, and reactions at the fingertips of the prosthesis. For the Raptor prosthesis, aspects such as dimensional precision of the prosthetic model, ease of assembly, construction speed, and low production cost will be evaluated. The study seeks to contribute to the understanding of the mechanical performance of these hand prostheses, verifying their mechanical viability and assessing their functionality and applicability in the context of the needs of patients with physical disabilities.
