Vesarien have seemingly taken the first steps of any producer of graphene and are looking at the potential for 3D-printing graphene. They have started trials through their subsidiary 2D Tech with E3D Online in the feasibility of producing commercial quantities of 3D printed parts containing graphene.
It was proved by researchers at Imperial College London that it could be done, reporting it in Advanced Materials in January 2015. They used Fused Deposition Modelling (FDM) to develop a type of filament that consists of modified graphene flakes (of graphene oxide) in a responsive polymer that allows its bonding to other layers, something that the hydrophobic graphene doesn’t do in water-based inks. Further details can be found in the original editorial.
