Prosthetic leg maker Ricardo Rookie Anievas makes house calls all over the Philippines. 1.2 million people in the country need prosthetic legs, primarily due to amputations following complications from diabetes. Rookie works at the Manila office of a Japanese company led by engineer Tokushima Yutaka, where a dedicated team has developed technology to make 3D-printed prostheses. The 3D-printed legs cost just one-tenth that of a regular prosthesis, making it possible for many more Filipinos to get their lives back on track.
