Interdisciplinary Contributions in the Design of Assistive Products With 3D Printing Technology

This work shows an interdisciplinary approach between product design, psychology, and electronic engineering disciplines. The contributions, knowledge, and results for the creation of assistance products from this research process are focused on the principle of inclusion of people with disabilities. The review of the scientific literature on the topic addressed is related to human-centered design from a comprehensive vision that recognizes needs while respecting the principle of individuality. The hypothesis suggests that products designed for individuals with disabilities gain significance when developed through an interdisciplinary approach within the context of collective knowledge-building. This process was carried out using additive 3D printing technology. We worked through a case study and functional prototyping of an upper torso exoskeleton and arm exoprosthesis for people with the total absence of both upper limbs. This project's main objective is to offer accessible resources that improve the quality of life of people with physical disabilities. The main results are an iterative synergy between the actors, a functional and personalized product, and a valorization of assistive technologies and materials for a practical design.
