Some artists are embracing 3D printing as a new medium, allowing them to create intricate 3D compositions that are difficult to produce in any other way. But the rigid, plastic-based materials used in many 3D printers require high heat for workability. Now, researchers reporting in ACS Omega have developed a colorful new ink for 2D and 3D art made of mica pigments in alginate, a sugar from seaweed that forms a stable gel without heat.
