Laser Holograms Create 3D-Printed Objects in Seconds

(NewAtlas) A team of scientists and engineers led by Lawrence Livermore National Laboratory (LLNL) has developed a process that uses hologram-like lasers to make complete objects in seconds inside a tank of liquid resin. Called volumetric 3D printing, the process overcomes many of the limitations of conventional additive manufacturing.
“The fact that you can do fully 3D parts all in one step really does overcome an important problem in additive manufacturing,” says LLNL researcher Maxim Shusteff. “We’re trying to print a 3D shape all at the same time. The real aim of this paper was to ask, ‘Can we make arbitrary 3D shapes all at once, instead of putting the parts together gradually layer by layer?’ It turns out we can.”
