3 Dimensional Printing Machine Can Now Make Copies Hair


Charlotte - 3D printing machines today are already quite advanced, the food until prosthetic hands that can function had been able to be printed.

Not only that, after a hard and solid objects, now printing machine is thought to be able to make a copy of the strand, like threads and wigs.

Reported from Science Daily, researchers from Carnegie Mellon University found a way to produce strands of fiber and yarn with outstanding quality printers and at an affordable price.

Technique produces 3D hair similar to - and inspired dari-- sheet plastic piece that is created when someone uses hot glue.

"You just punched out material in small amounts, then pulled it," said Gierard Laput, Ph.D.. D. with a major in Human-Computer Interaction Institute of Carnegie Mellon. "The idea is really simple."

Produced plastic hair strand by strand, the process is not instantaneous - it takes approximately 20 to 25 minutes to create jumputan hair on the surface area of ​​10 square millimeters. However, you do not need special hardware, just a set of additional parameters in the 3D print job.

The results that have been printed hair can be cut, digelombangkan by blowing with hot air, or braided, just like human hair or a wig. As for the hair with a larger diameter and can be used as a stiff bristle brush.

Laput and colleagues, fellow students HCII Ph. D., Anthony Chen Xiang HCII and a teaching assistant, Chris Harrison, will present this method on 11th November in Uist in 2015, at the ACM
User Interface Software and Technology Symposium, Charlotte, NC.


Researchers developed a technique using printer models fused deposition modeling (FDM). FDM uses a plastic filament that runs through a heated nozzle. With a tiny tip, the tool will form tiny fibers evenly from melting materials to form patterns, layer to layer, to copy 3D reached. FDM printer is not expensive, and colleagues used Laput only $ 300

To make fibers such as hair, researchers simply need to fill in a bit of melted plastic and pulled the nozzle tip quickly. But there is one problem, according Laput, head of the printer is not designed to rise rapidly, and not fast enough to produce a piece that tapered shape.

The solution is to approach the problem from different sides - literally. Although the head end printers can not move quickly, they apply a material melting and position the head and the base to the side, they can create a strand of 'hair' as desired.

Laput and colleagues have use traditional techniques to make hair in various colors for a printed copy of a 3-dimensional, ranging from spiky hair troll, long hair for wizards like Gandalf, or the tail of a horse. With roots that randomized position, they can create natural-looking hair, while the position of the hair roots are evenly used to make hair toothbrush.

Researcher using ordinary ingredients such as polylactide, or PLA for the project. According Laput, using expensive materials, such as acrylonitrile butadiene styrene (ABS) will enable to create hair that is magnetic.
