Metal Reprap 3D printer?

[Nistrum]

the problem is that you will weaken the structure making it useless for a lot of uses.. that striation and the fact that each layer cools between applications will in effect create the same problems as cold solder joints...useful for some applications obviously but cast and milled metal objects will still be stronger. TBH i think the best way to do it is print your object and pay a metal caster to cast your object for you...

If you read my post carefully, I already mentioned a solution to this.
