Wow - that IS high current. It can even light up

a green LED.

Baked at 600 to 900F, the binder is supposed to evaporate and leave only metal. Of course, I think it would require a glass or ceramic substrate, FR4 won't stand up to it.

I wonder how fine you could make the traces, and if you could solder to them. However, this seems like as much or more trouble than toner transfer, milling, direct inkjet, or photo.
