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 […]
Open source USB stack HID development update
