Researchers 3 Years Away from Commercializing Pure Graphene 3D Printers

Note: this is not like 3D printing of sizable structural elements, but more akin to printing out  microcircuitry. The concept seems straightforward enough… a liquid slurry of tiny sheets of graphene oxide is simply printed using a micropipette, with the liquid evaporating away and leaving the trail of graphene behind it (I’m guessing the tiny sheetlets stitch themselves together).

Where the process gets tricky… the article says the liquid used is hydrazine. Granted, the quantities used would probably be miniscule, but still… fricken’ hydrazine.
