Researchers open hairy new chapter in 3-D printing

Researchers have found a way to bypass a major design step in 3-D printing, to quickly and efficiently model and print thousands of hair-like structures. Instead of using conventional computer-aided design (CAD) software to draw thousands of individual hairs on a computer the team built a new software platform, called 'Cilllia,' that lets users define the angle, thickness, density, and height of thousands of hairs, in just a few minutes.
