Wool

Deep within the bowels of Disney Research, there is a team tired of 3D printing items with sharp corners.  They have developed a method of using wool and wool blend yarn to print CAD objects.  The printer uses a sewing machine style needle to gradually build an object.  The printing technique can also be used to layer around other items, such as electronics or stiffening mesh.  While you likely won’t be purchasing a custom printed Goofy from a cart in the Magic Kingdom anytime soon, the implications of this type of 3d printing are very exciting.  Click through to see a video of it in action.
