In 2013 researchers at Princeton University created a “bionic ear” – capable of detecting frequencies a million times higher than a human’s hearing range, and manufactured by blending biological tissues with electronics via a 3D printer. First invented in 1984, 3D printing is now capable of producing human organs and limbs, NASA rocket engine parts, car chassis, entire five-storey concrete houses and more. The possibilities are mind-boggling.
The design world has cottoned on to the possibilities of 3D printing too, using it to create everything from crockery to lampshades, while watchmakers have used the precision it affords to create intricate mechanisms and entire watch cases. But while there is a clutch of jewellers championing this new technology, others are disparaging about its use.
