DESENVOLVIMENTO E ANÁLISE DE PRÓTESES PERSONALIZADAS UTILIZANDO COMPÓSITOS DE PLA-CL COM FOCO EM MANUFATURA ADITIVA E INTEGRAÇÃO SENSORIAL

Abstract

The widespread availability of 3D printing and low-cost myoelectric modules enables affordable didactic prostheses, yet a gap remains between hobby prototypes and stable, reproducible, easy-to-maintain devices. This work addresses that gap by developing, on the bench, a single-finger prosthetic mechanism actuated by EMG and fabricated from polymer materials, integrating a microcontroller and a servomotor into a simple, modular architecture. The contribution lies less in novel components and more in process organization: the use of quality-engineering tools to prioritize sources of instability, guide interventions, and document design decisions in a transparent, replicable way. The outcome is a practical path from design to functional validation, with instrumented firmware, standardized telemetry, and defined performance criteria that allow measuring progress and comparing versions. Although not a device ready for human use, the prototype and its methodology provide a solid foundation for continuation in academic and outreach settings, reducing the learning curve and expanding access to evidence-driven myoelectric solutions.
