This article presents a 3D-printable prototype design for a prosthetic arm that can be controlled by flexing any muscle in the user's body through a sensor that collects electromyographic (EMG) signals from the muscle. The development of this type of prosthesis exists in the literature, but it is expensive; Therefore, the aim of this project was to demonstrate the feasibility of using 3D printing technology to build a prototype of a controlled arm as the first step towards the development of low-cost prosthetics as a possible aid for low income people with disabilities.
