The other approach is through a copper ink such as this one: http://copprint.com/

This looks cool and could be a much easier solution than the aforementioned laser/printing setup. Judging from the website though it doesn’t look like they have a product ready to go, is that true, and are there any alternatives? It would be nice if there was a filament I could just plug into my 3D printer and start using :p
