Researchers at Carnegie Mellon University have discovered a revolutionary method for creating lifelike hair fibers that only requires a common, inexpensive fused deposition modeling (FDM) printer.
The technique is surprisingly simple yet extremely effective: the printer squeezes out a small dollop of molten plastic and then pulls away, stretching the material into a long strand.
Though the process is long, the resulting product is reportedly quite lifelike and can be styled just like the real thing. Plus, depending on how densely the fibers are packed and their positioning, they can potentially be used in a variety of applications -- from hairpieces to toothbrush bristles. This technique extends the capabilities of 3D printing in a new and interesting way, without requiring any new hardware.
