prehensile hand 800x450

According to the inventor, Fraser Leid, “the Inspiration behind the Printed Prehensile was the idea that it came in a kit — something that a person without the limb would be able to buy and have assembled — which in turn, would greatly lessen the cost of the prosthesis and also allow the user the opportunity to personalise it (Hands building Hands).

The system is a blend of various thicknesses of ABS Plastic and Aluminum fittings, which either are assembled with cap screws or as a snap-fit. An interesting take on the idea was to integrate Nylon cord as the material required for flexor and extensor movements, as well as individual coiled springs to help the fingers to reset.
