Rami is a running-specific prosthetic limb created by Professor Shunji Yamanaka from the Yamanaka Prototyping and Design Lab in the University of Tokyo. It is a part of the MIAMI Project (Manufacturing Initiative through Additive Manufacturing Innovation) and began being developed in 2014. I joined the project between 2016 and 2018.
Rami is a prosthetic limb designed for paralympic runner Saki Takakuwa. It is an evolution of the previous prosthetic limb Yamanaka developed for her, Rabbit. Rami's socket is 3D printed in SLS and its engineering has evolved enough to allow it to be used in competitions.
While 3D printed sockets are usually heavier and more frail that traditional sockets, the constant testing and alterations on Rami have made it lightweight and resistant to a point that it can be compared to handmade sockets.
