Over the past few years the number of 3D printers used by medical professionals has been skyrocketing, but in the majority of cases they seem to be used for little more than excellent surgical models for prepping operations. However, a case from Virginia serves as a reminder that the technology can already make significant impact as an implant manufacturing tool. Ruth Smith-Leigh definitely agrees, as her leg was saved thanks to the help of a 3D printed implant. After suffering a terrible injury in a car crash, she was told her leg needed to be amputated. Fortunately, a 3D printed alternative instead enables her to continue to walk.
