Holograms Supercharge Nanoscale 3D Printing

Using holograms, a nanoscale 3D printer can now rapidly fabricate complex items with details smaller than a wavelength of visible light, a new study finds. This research can rapidly manufacture nanotechnological arrays of wires, lenses, rotating magnetic gears, and other structures—suggesting applications in electronics, photonics, microrobotics and more.Currently, the most…
