Michelangelo's original statue of David, which was completed in the early sixteenth century, is among the world’s most famous works of art. While the 5.17m original was sculpted from marble, many replicas since have been created in bronze, plaster and fibreglass.
Now, ETH Zurich scientists have created a unique version of the famous statue by 3D printing a millimetre-scale David in pure copper.
The researchers created two tiny sculptures: a 1mm David and a second one which is ten times smaller (merely the height of the other's pedestal). 3D printing such small structures can be troublesome due to the difficulty achieving the required resolution.
