High-resolution 3D printing in seconds

[erek]

"In the Star Trek universe, devices called replicators can manifest solid matter in seconds. Thanks to advances in materials science, these science-fiction devices might be closer to reality than we think. A type of 3D printing called volumetric additive manufacturing (VAM) uses light to rapidly solidify an object in a volume of a liquid precursor. Writing in Nature, Regehly et al.1 report an advance in VAM that allows solid objects to be printed with a feature resolution of up to 25 micrometres and a solidification rate of up to 55 cubic millimetres per second. The authors call this process xolography because it uses two crossing (x) light beams of different wavelengths to solidify a whole object (holos is the Greek word for whole)."

Very impressive... but sadly, not usable in the USA since it only prints in metric: "feature resolution of up to 25 micrometres and a solidification rate of up to 55 cubic millimetres per second"
