3D printing has proven itself useful in so many industries that it’s no longer necessary to show off, but some people just can’t help themselves. Case in point: this millimeter-tall rendition of Michelangelo’s famous “David” printed with copper using a newly developed technique.
The aptly named “Tiny David” was created by Exaddon, a spin-off company from another spin-off company, Cytosurge, spun off from Swiss research university ETH Zurich. It’s only a fraction of a millimeter wide and weighs two micrograms.
It was created using Exaddon’s “CERES” 3D printer, which lays down a stream of ionized liquid copper at a rate of as little as femtoliters per second, forming a rigid structure with features as small as a micrometer across. The Tiny David took about 12 hours to print, though something a little simpler in structure could probably be done much quicker.
