Homebrew PCBs

Copper is an amazing conductor of heat. Bringing the copper-touching toner to a fusible temperature without the laser-facing top layer vapourising would be very difficult.

That said, try it and report back! If it does work, it could be very useful.  I would start with a warmed PC board (close to but below fusing temperature) to minimise the loss.

And good luck.
