Action figures

From PCmag:

Three-dimensional printers build objects layer-by-layer out of different materials like plastic, wood, or even chocolate, and can be been used to create toys, jewelry, car parts, and incredibly, artificial limbs. Print jobs of animated 2D characters presumably don't have to be quite as precise as a prosthesis, though. "In animation you're not necessarily trying to model the physical world perfectly. The model only has to be good enough to convince your eye," Harvard researcher Moritz Bacher told BBC News. It's easy to make characters so anatomically skewed that they could never achieve true physical presence, the researcher said, especially since video game characters are built to somewhat resemble humans, but without the same bodily expectations. The new software works hard to build something concrete out of a bunch of pixels-it identifies ideal locations for a figure's joints, then optimizes the location and the size, all while enhancing a character's "skin" texture, allowing details like a snake's scales to appear on the final product, according to BBC News.
