An outline of the engineering requirements for a prosthetic hand has been described in this book where the techniques and ideas presented are also applicable to robotic hands. Of all the components that form the system of an artificial hand, it is perhaps the algorithms, sensors and the processing of signals that will play an increasing role to improve the functionality of advanced hand designs. The new developments in 3-D printing (additive manufacturing) allow for custom-made designs, modular components and low cost in the development of designs. However, the polymer-based materials have non-isometric properties and can be relatively weak compared to blocks of materials that are machined into the desired shape. Also if a high tolerance is required, then a 3-D printed component may lack the precision required. This technology has seen considerable development in the recent years and opens up the possibility of low cost and modular component design. Further developments, especially using low-density metals, will greatly enhance the durability of future prosthetics.
