Scientists at the University of California, Berkley, have invented something straight out of Star Trek: a 3D printer that builds objects with light.
Nicknamed “The Replicator,” this new technology works more like a CT scan than a 3D printer. It scans an object from all sides, then projects the shape into a tube of synthetic resin. the resin hardens wherever the light hits, ultimately forming the scanned image.
While this technology can revolutionize manufacturing, it is still in early development. For now, the replicator can only make small objects. As a demonstration, the scientists made a miniature version of Auguste Rodin's famous statue, "The Thinker."
