Just think of the plusses!
You dont solder to put your components on, you just need to warm it up and stick em in! =)
You start off by putting the negative space (insulator) down with some kind of insulator (maybe just give it a clay base?), then you pull out the positive space extrusion, and the lead is supposed to go into these cracks from so many pipe ins, that you snip off afterwards.
I havent fully thought it through, maybe I better get back to thinking about it.
