Life-saving printout

3D printers have truly reached the mainstream when they start saving babies' lives. Researchers at the University of Michigan have printed a bioresorbable splint to allow a baby with the life-threatening condition, tracheobronchomalacia, to breathe easy again. Glenn Green and colleagues were granted emergency clearance from the US Food and Drug Administration to create and implant a polycaprolactone tracheal splint for the baby based on a high-resolution body scan and a computer-aided design to drive the printer. By the time the child reaches his third birthday, he should be in good health and the polymer splint will have been degraded naturally by his body.
