Desarrollo de prótesis de mano fabricadas mediante tecnología de impresión 3D para trabajadores con amputaciones de dedos por accidentes laborales

This research work focuses on the development of hand prostheses using 3D printing technologies, with the aim of providing functional, accessible and customizable solutions for people with amputations. First, the essential movements and grips of the hand are identified, along with the specific needs of the users. In parallel, the functionality of existing prostheses was analyzed, as well as the materials and technologies available for their manufacture, evaluating aspects such as cost, resistance and sustainability. The results revealed that 3D printed prostheses have notable advantages over traditional methods, mainly in terms of cost reduction, speed in manufacturing and the possibility of customization. However, areas for improvement were identified, such as the need to integrate more durable materials, improve ergonomic adjustments and optimize movement mechanisms. The resulting proposal includes the design of ergonomic, light and accessible prostheses, which have been optimized through user testing to ensure their functionality. Likewise, the importance of establishing strategic alliances between health centers, educational institutions and local manufacturers is highlighted, in order to promote the massive implementation of 3D printing technologies in the production of prostheses. This would contribute to expanding access to larger medical devices, improving the quality of life of users. It is concluded that 3D printing represents a transformative and viable tool in the field of rehabilitation, with the potential to continue innovating in future technological developments
