Print nanometer precision 3D objects at high speed
Researchers at the Vienna University of Technology developed a process to speed up high precision 3D printing. A focused laser beam cures resin and develops a hard object just a few hundred nanometers wide.
This method is well known, but what sets this printer apart is the new control mechanisms for the mirrors that focus and position the laser, as well as improvements in the Resin chemistry.
Normal laser/resin 3D printers of this precision have a speed of a few millimeters per second, while theirs has the speed of a few meters per second.
