"3D Printer Creates The Worlds Smallest 3D Printed Objects (Video)"

3D printing is becoming more popular, and now researchers at the Vienna University of Technology have created a new 3D printer that is capable of printing 3D objects on a nano-scale.

The 3D printed objects, which you can see in the photos below are actually about the width of a human hair, and they are printed using resin and a high precision 3D printer, have a look at the video below.

3D Printer

The 3D printer 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 polymerized line of solid polymer, just a few hundred
nanometers wide. This high resolution enables the creation of intricately structured sculptures as tiny as a grain of sand. “Until now, this technique used to be quite slow”, says Professor Jürgen Stampfl from the Institute of Materials Science and Technology at the TU Vienna. “The printing speed used to be measured in millimeters per second – our device can do five meters in one second.” In two-photon lithography, this is a world record.

You can find out more information about this amazing technology over at the Vienna University of Technology .
