3D printing is leading to a lot of amazing breakthroughs. 3D bioprinting may lead to even more. We've heard of companies 3D printing human organs, and others who are looking to 3D print edible meat and leather. Now, one company is looking into 3D printing synthetic rhinoceros horns which are biologically the same as the real thing. The idea it to prevent the massive amount of poachings that take place each year, driving many species of rhinoceros to be classified as critically endangered and other into extinction. It should be interesting to follow this story and see what comes about from it. Read and see more at: http://3dprint.com/47469/3d-printed-rhino-horns/
