Electro plate prints.

[old man emu]

To get the small amount of copper sulphate and sulphuric acid that you need, why don't you contact your local high school and arrange to give a demo of 3D printing in exchange for the chemicals from their science lab stocks?

Roxy, Yes, the copper wire would get a plating of silver, but only a few millimetres of copper wire would be exposed, so it would be no problem.

Using graphite, just check the conductivity of a heaped teaspoon of it with your multimeter.

Actually... Isn't this a non-issue? Obviously the graphite conducts enough to cause 'some' electroplating of metal to happen. So as soon as there is enough of this process from the start with graphite... Pretty soon we have a copper skin conducting across the entire surface area working for us. Right???
