New Technique Allows Faster 3-D Printing | SIGNAL Magazine

By using laser-generated, hologram-like 3D images flashed into photosensitive resin, researchers at Lawrence Livermore National Lab (LLNL), along with collaborators at UC Berkeley, the University of Rochester and the Massachusetts Institute of Technology (MIT), have discovered they can build complex 3-D parts in a fraction of the time of traditional layer-by-layer printing, according to an LLNL press release.

“The fact that you can do fully 3-D parts all in one step really does overcome an important problem in additive manufacturing,” said LLNL researcher Maxim Shusteff, the paper’s lead author.

“We’re trying to print a 3-D shape all at the same time. The real aim of this paper was to ask, ‘Can we make arbitrary 3-D shapes all at once, instead of putting the parts together gradually layer by layer?’ It turns out we can.”
