MIT brushes up on 3D-printing hair

Researchers at MIT Media Labs have created a method to 3D print hair structures, which have all kinds of surprising applications. View gallery (7 images) Researchers at MIT’s Media Lab have developed a method for 3D printing hair structures with a diameter as small as 50 micrometers each. With the ability to create finely detailed surfaces, touch sensors and even actuating motors, the technology could be used to make customized paint brushes, Velcro-like mechanical adhesives, and touch-sensitive plush toys. Adjusting the hair’s tilting angle before printing directs which way objects move when the structures are used as an actuator […]
