Enzo Romero, who was born with one hand, was inspired by the Star Wars character Luke Skywalker to get a prosthetic arm for himself. As a young adult, he moved to Lima to study mechatronic engineering and while doing so, came up with a way to 3D print prosthetic arms using melted plastic bottles! He printed a bright blue arm for himself with this new process that brought down costs significantly.
According to a 2019 research paper, the number of worldwide upper limb amputees in that year was 3 million out of which 2.4 million live in developing countries. Depending on where one lives, getting a functional prosthetic limb could easily go into tens of thousands of dollars and these high costs can especially be prohibitive in developing countries.
