Nanoscale 3D Printer

An innovative laser lithography method was used to print this mini-space craft

Nanoscribe GmbH, a company formed by the Karlsruhe Institute of Technology, has shown a laser lithography method that can make minute 3D objects smaller than the diameter of a human hair.

3D laser lithography systems are used in research around the world in various fields, such as replacing conventional electronics by optical circuits for greater performance. Nanoscribe systems are used to create polymer waveguides that allow data transfer rates greater than 5Tb/s. They are also used to create new materials and to create scaffolds for cell growth research.

The new 3D printer made by Nanoscribe is 100 times faster than current technology allows, with the mini-rocketship in the photo above taking about sixty seconds to produce. This speed is the result of utilizing a galvo mirror system similar to the technology that focuses a CD player’s laser.

The laser is focused on a photosensitive material that dissolves, or does not dissolve, to produce the finished object. Watch this amazing video of how the spaceship was printed.
