The Enable Community Foundation is teaming up with GrabCAD to challenge GrabCADs large and diverse population of talented engineers to design a modular, low-cost, 3D-printable terminal device that is compatible with the International Committee for the Red Cross’s (ICRC) transradial prosthetics manufacturing guidelines. With the help of these participants, we can continue to break down barriers for those with limb differences.

Why this is so important:

In the US alone, there are nearly 2 million individuals living with limb differences. Globally, there are countless more. The World Health Organization estimates that approximately 1 in 2000 live births each year involve upper-limb reductions. For those with upper limb differences, there is often little diversity in aesthetics or functionality due to the manufacturing and distribution processes that have been historically used for creating low-cost prosthetics and much of what is available is based on designs from the 70s and 80s.  A 2012 VA study found that since 1987 the mechanical efficiency of voluntary opening (VO) terminal devices has actually declined and that traditional hooks still outperform more cosmetic hands in both weight, grip strength, and mechanical efficiency.
