Researchers Make Major Graphene 3D Printing Breakthrough

We have already seen a number of breakthroughs within the 3D printing and graphene spaces. Today we have published an article relaying a recent breakthrough by researchers in Korea who have discovered a method of 3D printing pure graphene nanostructures. The method relies on a chemical reaction during extrusion, forming graphene oxide which can be 3d printed with. The full details on this method can be found here: http://3dprint.com/27324/graphene-nano-3d-print

Below is a picture demonstrating the process of 3D printing entire graphene nanostructures. Let's hear your thoughts on where this may lead us!
