In the past making complex large 3D structures would take hours or even days but with the newly developed 3D laser printer the scientists can speed that up by a factor of 500 to 1,000 times.

  • The process called “two-photon lithography” involves using laser beam to harden liquid resin in order to create micro objects of solid polymer. The scientists said the technique could be developed to make all manner of small parts including biomedical items for use by doctors. Credit: Herwig Prammer / Reuters

  • Researchers at the Vienna University of Technology this week said they have created a 3D printer that is orders of magnitude faster than similar devices opening up all manner of new applications for manufacturing small parts. Known as "two-photon lithography" the technology can create “grain of sand-size structures in just four minutes,” the university said.

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 nanometers wide, the university said.
