Go nano, go...

3D printing has improved a lot those recent years. But why make it simple? One nanometer (nm) = 1/1,000,000,000 meter! 
Those pieces are gigantically small...

Detail of the racecar
"Printing three dimensional objects with incredibly fine details is now possible using “two-photon lithography”. With this technology, tiny structures on a nanometer scale can be fabricated. 
Researchers at the Vienna University of Technology (TU Vienna) have now made a major breakthrough in speeding up this printing technique: The high-precision-3D-printer at TU Vienna is orders of magnitude faster than similar devices (see video). This opens up completely new areas of application, such as in medicine."

Surprising Three Dimensional Objects, Nano Printing

  "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."
