A team at Carnegie Mellon University, came up with design and its concept actually seems very familiar to crafters everywhere. Inspired by the techniques in handling a glue gun, they used a conventional fused deposition modeling (FDM), which is a form of 3D Printing, to fabricate these types of plastic hairs. You know when you are using a glue gun, you finish adhesion and pull it away, a small thin thread of melted plastic trails off still attached to the target. The team admits in their paper to “exploiting” this phenomenon so that users can fairly easily add hair, fibers, or bristles to any selected area of their model. I wonder if it will help all of us who need hair!
