Resumen: The anthropomorphic design of prosthetic fingers with 2 degrees of freedom for transradial myoelectric prostheses with pulleys-pulleys transmission mechanism allows to perform 4 types of movements in each finger (flexion, extension, adduction, abduction), and 6 ways of grasping in a prosthetic hand (Rest, clamp, tripod, spherical, cylindrical and palmar extension). Through the use of a 3D scanner, the injured hand of the patient was digitized, thus personalizing the design of the fingers and the mechanisms, through modeling and simulation in Autodesk Inventor. The distal and middle phalanges were designed as a single rigid element to reduce the loss of strength in the fingertip of the prosthetic, obtaining a force of 4.6N. In the design phase, important factors were considered for the mechanical resistance in the additive manufacturing with ABS, such as the orientation, speed, density, direction of rolling and layer height, allowing to reduce manufacturing time and costs.
