a larger than life hand prosthesis

Fraser Leid, a student in Industrial Design in England, managed to create a prosthesis imitating the 27 bones of the hand with a 3D printer.

3D printing today makes it possible to design just about anything and everything, be it food, missing parts to operate an object, and even contact lenses, this new technology seems limits. Latest feat, complete hand creation by a student in Industrial Design. Printed Prehensile is an articulated bionic prosthesis which has, just like a human hand, a skeleton, whose 27 bones that compose it are fully 3D printed.

These 3D printed bones are made of aluminum as well as coil springs and to allow each finger to bend and unfold, nylon cords (two per finger) are responsible for doing the work and sheltered in a metacarpal accommodation. The other ABS plastic parts making up the bionic hand are first 3D printed and then assembled individually using stainless steel screws or gaskets. If at present this 3D printed hand is still in the prototype state, its creator Fraser Leid hopes to have a more refined version of his creation within a year.
