RESEARCH ON 3D DESIGN OF A CUSTOMIZED BIOMECHANICAL PROSTHESIS FOR THE UPPER LIMB (FOREARM)

This paper analyzes the computer-aided design (CAD) process applied to the realization of a personalized biomechanical forearm prosthesis. The goal is to restore the functionality of the upper limb through a device anatomically and biomechanically adapted to the individual needs of the patient. The paper covers the essential stages of the CAD methodology, from the collection of anthropometric data and 3D scanning, to the modeling of parts, kinematic simulation and finite element analysis (FEA). The importance of customization, structural optimization and integration of functional components (mechanical and electronic) in the context of a modern prosthesis is highlighted. Virtual simulations allow for design validation before manufacturing, ensuring a balance between performance, comfort and durability. Case studies and simulation examples confirm the technical feasibility of such an additively manufactured prosthesis (e.g. 3D printing), demonstrating the potential of this type of approach for future prosthetic solutions.
