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”.

BioBot: a Desktop 3D Printer for Living Tissue


According to the Biobots,” a Philadelphia based startup has developed a desktop 3D printer for printing biomaterials.  The 3D printer called BioBot 1 was demoed at TechCrunch Disrupt NY in May 2015.  Biobots was found the most innovative startup out of 48 startups at the SXSW Accelerator in Austin.

Biobot 1 uses a compressed air pneumatic system that allows it to precisely control the printing operation.  Biobots has developed biomaterial that is placed in the syringe along with cells for printing.  The biomaterial hardens as it is extruded.  Biobot 1 uses visible blue light to cure the biomaterial.  Unlike UV light, visible blue light is not harmful to living tissue.  The technology can be used to 3D print living tissue such as cartilage, bone, or liver.  The technology can find valuable applications in the clinical development of the drug.

Biobots aims at bringing down the cost of bioprinting significantly.  Typical bioprinters cost in the range of hundred thousand dollars. Biobots managed to bring down the cost by an order of magnitude.  Biobot 1 is also designed for ease of use.  According to Danny Cabrera, co-founder of Biobots, “As soon as you get a BioBot, you can print something. What we’re doing is we’re saying anybody can do this. [It’s] this MakerBot of biology idea.”
