This is actually a pretty neat development. For years the open source 3-D printing crowd has been talking about 3-D printed electronics. With this ink it is possible to print out conductive surfaces. The technique uses graphene with ethanol as a solvent and ethyl cellulose as a stabilizing polymer, neither of which leaves a residue, and only the graphene remains.
So has anyone tried to mix graphene with plastic. With a multihead 3D printer, the circuits could be embedded and distributed within the object. Hmmm…Would you just use conductive plastic to solder on the components?
hmmm yea but u know, joining together 3d electronics + existing electronics packages. if tomorrow we have some sort of printer, surely there needs to be a joining format to put in some FPGA, BGA, SMD, etc. if leads are to be embedded then the printer will have to be able to pick and place components somehow, or its a 2 parts process, print, manually place, print again to encase or something like that …
