The popularity of myoelectric prosthetic hands increases as technological advances allows for the sophistication on prosthetic devices to become more affordable. A 3D printed myoelectric prosthetic hand was designed to ensure that it is cost-effective whilst having functionality similar to commercially available prosthetic hands. A three-fingered prosthetic hand was designed to grip objects of different shapes using one grip. An electromyography control system was investigated by performing tests on an able-bodied person and observing the results. The electromyography control system for the prosthetic hand was then designed. The prosthetic hand was then tested by an amputee by gripping objects of different shapes and sizes to determine its practicality of the prosthetic hand. The prosthetic hand was capable of picking up the object in 50% of its tests and showed a grip strength of 30.4 N and a response time of 4.5 seconds.
