Real-life version of Star Trek’s ‘replicator’ 3D prints full objects in seconds

Inspired by Star Trek ’s “replicator,” a machine capable of synthesizing objects on demand, researchers from Lawrence Livermore National Laboratory (LLNL) and the University of California, Berkeley, have developed a new, potentially game-changing type of 3D printer . Instead of building objects layer by layer, as conventional 3D printing methods do, this new printer is able to print entire objects at once — using projected light to transform gooey resin into solid finished pieces. “We’ve invented a new category of 3D printing process inspired by the principles of computed tomography (CT),” Hayden Taylor , an electrical engineer at UC Berkeley, told Digital Trends. “CT is widely used in 3D medical and industrial imaging, but hasn’t previously been applied to fabrication. Our new process is called Computed Axial Lithography (CAL), and prints entire 3D objects into light-sensitive materials all at once. The process involves rotating a container of light-sensitive material, […]
