3D Printers Disrupting Copyrights and Patents (2013)



According to 3D Printers Disrupting Copyrights and Patents,” It wasn’t too long ago that DIY 3D printers started making the news in geek circles. It captured the imagination of some and was largely ignored by others. I was somewhere in between until a few days ago. I’ve since slid somewhere closer to imagination, perhaps because someone printed a rotor from a Wankel engine”. […]

Carnegie Mellon University 3D Prints Hair

Image Posted on Updated on

According to the Researchers and Carnegie Mellon University,” have developed a technique for 3D printing hair, fibers or bristles.  The researchers used a fused deposition modeling (FDM) printer.   The technique is similar forming thin strands by extruding glue from a hot glue thing and suddenly moving the hot glue away. Similarly, the technique extrudes molten plastic from the nozzle of the 3D printer and then moves the nozzle away rapidly.  The researchers call the technique fabrication.

3D printers typically can not move the nozzle up rapidly.  However, they can move the the nozzle sideways with respect to the print bed rapidly.  Therefore, instead of moving the nozzle up, the researchers moved the nozzle sideways.  The amount of molten plastic extruded and the speed with which the nozzle is moved away can be varied to control the thickness of hair generated.  These parameters are programmed into the 3D printer.

The technique presently creates hairs strands by strands. Therefore, the process is slow and takes 20-25 minutes to generate hair on 10 square mm2. Different types of material can be extruded from the 3D printer to create hair having different properties.The technique can be used to add hair to 3D printed objects, for example, hair on a head, whiskers, or hairy tails”.
