Researchers at the Vienna University of Technology improved
3D-printing technology using two-photon lithography, they
developed a process by which one can generate three-dimensional
objects, they are several orders of magnitude faster and smaller
than the existing counterparts. In the process of 3D printing
using liquid resin that hardens in place, which focuses the
laser beam. Coordination of the beam by means of movable
mirrors, which allows to produce parts from a solid polymer with
up to hundreds of nanometers. 1. Micro-model race car. 4. This
new solution allows you to create complex structured sculptures
not bigger than grains of sand. “Until now this technique has
been used quite slowly,” said by Prof. Jürgen Stampfl (Jürgen
Stampfl) from the Institute of Materials Science and Technology
of Vienna University of Technology. “Previously, the print speed
is measured in millimeters per second – our device can operate
at speeds of up to five meters per second.” 6. A total of 4
minutes, it can generate 100 l
