This racing car is the size of a grain of sand.

This racing car is the size of a grain of sand. Researchers at the Vienna University of Technology used a 3D printer with nano precision to break the world record for fastest two-photon lithography. The technique sees liquid resin hardened at precisely the correct spots by a focused laser beam. The focal point of the laser beam is guided through the resin by movable mirrors and leaves behind a polymerized line of solid polymer, just a few hundred nanometres wide. This high resolution enables the creation of intricately structured sculptures as tiny as a grain of sand...
