Endangered Rhinos: Wildlife Conservation With a 3D Printer
Practically all species of rhino around the world are now endangered, their numbers depleted by poachers who then sell their horns on the lucrative black market. Demand is especially high in China and Vietnam, where rhino horns are used for medicinal purposes. A biotech team in the US, however, is now making bioengineered replicas of horns with a 3D printer that are visually and genetically identical to the real thing. They hope to flood the market with their cut-price versions, and put the poachers out of business. Opinion is divided over whether the concept will actually work.
