Honey, I shrunk Michelangelo’s David

Researchers in Zurich have reproduced Michelangelo's David as a miniature in metal. Their achievement highlights the potential of a special 3D printing method developed at ETH. There he is, standing upon his pedestal: David by Michelangelo. A world-famous statue that nearly every child can recognise. But this David is just 1 millimeter tall, pedestal included, and is made not of marble like the 5.17-meter original, but of pure copper. It was created using 3D printing by Giorgio Ercolano from Exaddon, an offshoot of ETH spin-off Cytosurge, together with the team led by ETH Professor Tomaso Zambelli from the Laboratory of Biosensors and Bioelectronics. Zambelli and his team developed the 3D technique a few years ago.
