3D-printed holographics can encode data using common plastic — keys and addresses up to 576 bits, with redundancy

The paper “Encoding terahertz holographic bits with a computer-generated 3D-printed phase plate”, available publicly on Nature.com, details a method of creating holographic storage with 3D printing and FOSS software.
