Using a $300 3D printer, researchers at Carnegie Mellon University (CMU) have developed a method by which to create 3D-printed hair, a feat that seems quite complex but is actually simpler than you might imagine. The team used the experience of hot glue as a model; when the glue gun is pulled away, a small strand is left stringing from the glued portion to the gun. The researchers at CMU took this application and applied it using a 3D printer to create synthetic, hair-like fibers that are quite like the real thing.
Able to be cut, washed and blowdried, the 3D-printed hair, while slow to create, is a step forward in manufacturing that the researchers believe could help revolutionize making hair for toys and beyond.
