Graphene is a material that has generated a lot of excitement, in the 3D printing industry and beyond. It's over 100 times stronger than steel, it's lightweight, and it's a great conductor of electricity and heat. The only problem with graphene, it seems, is that it's difficult to produce in bulk - or at least it has been so far. Researchers at Rice University and Tianjin University are working to change that, and they've broken some ground by 3D printing atomically thin graphene in centimeter-sized pieces.
