Article Summary
Are 3D printers not amazing enough already? Apparently some scientists at the Vienna University of Technology (TU Vienna) didn’t think so, as they have now built one that can create intricate objects as small as a grain of sand. While the ability to 3D-print such tiny items is actually not unique to the TU Vienna device, the speed at which it can do so is. According to the researchers, this makes the commercial production of things such as medical implants much more viable.
