A research team in Austria has set a world record for the fastest 3D-printed nano objects, capable of printing sculptures as small as a grain of sand, reports the BBC.

The scientists at Vienna University of Technology demonstrated this by printing a Formula 1 race car model measuring 0.285mm in length, a process that took a little over four minutes (the video below shows the 3D printing in real time). The car was made up of about 100 layers of liquid resin, each layer consisting of 200 printed lines.


Two-photon lithography makes it possible to create tiny structures on a nanometer scale. The high-precision 3D-printer technology developed by the university could be used to print small biomedical parts.
