3D printed finger helps British teen take exams following grisly cycling acciden

A British teen who almost died in a freak cycling accident is using a 3D printed plastic finger to get through his GCSEs. Oliver Smith, 15, severed a main artery and two nerves, causing him to lose most function in his right arm. One of the most important applications of 3D printing these days is using the technology to fix our broken bodies. 3D printed arms and legs are reshaping the way people think about prosthetics, while 3D bioprinting goes a step further, with scientists attempting to create 3D printed human organs out of stem cells.
