The bold black lines absorb more energy than the rest of the material, causing the plastic to contract—creating a hinge that folds the sheets into 3D shapes. This technique can be used to create a variety of objects, such as cubes or pyramids, without ever having to physically touch the material. The technique is compatible with commercial printing techniques, such as screen printing, roll-to-roll printing, and inkjet printing, that are inexpensive and high-throughput but inherently 2D.
