Researchers at the Vienna University of Technology have perfected 3D technology using two-photon lithography that can print orders of magnitude faster and smaller than similar devices.
The 3D printing process uses a liquid resin, which is 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 hardened line of solid polymer a few hundred nano meters wide.
This world is insane and those insane people keep on making us amazed.
