New 3D printer could create nano-devices in minutes



Researchers at the Vienna University of Technology (TU Vienna) have developed a 3D printing technology that can quickly print detailed objects in nanoscale using a process called two-photon lithography. It's fast, too: the precision required to print objects with features measured in hundreds of nanometers in width meant the speed of previous attempts at printing nanoscale objects were measured in millimeters per second. In contrast, the TU Vienna team's 3D printer is capable of printing lines of resin at a rate of five meters per second. In a demonstration shown in the video below, the team was able to print a nanoscale model of a 300-micrometer long Formula 1 racecar—made from 100 layers of resin, each consisting of approximately 200 individual lines—in four minutes.
