3D Printing with Light

Existing 3D printers of resinous materials, whether cured by light or air, require layering. Layering takes time; in his video on making molds for designer edibles, for instance, Eric Strebel pointed out that each print took 24 hours.

Seeking to speed the 3D printing process, a team of researchers at UC Berkeley have developed a new method: Computed Axial Lithography. By filling a cylinder with light-curable liquid resin, then rotating it while hitting it with a "dynamically evolving light pattern," they are able to cure the object in spins (perhaps a single spin?) rather than layers.
