New Open Sourced Metal 3D Printer

[RedSox2013]

Seems like this could end up being the Metal version of the Reprap. Hopefully this will lead to more competition in the metal printing niche, and drive prices way down similar to the declines in prices we have seen in the plastic niche.

I like the idea, seems a cool idea to be able to make a solid metal object from a model on your computer at home, I can also imagine it being fairly easy to build out of scrap parts, so pretty cheap.

I can see a few variable that would need fine tuning whilst using it:
Wire speed, Torch movement speed, Gas flow*, Current and Arc gap.

Also you may have to use a shielding gas* with Gas wire, rather than just Gasless flux cored wire.
Having the ability to use a Stainless wire with the correct gas would be good for making potentially food safe items.

Another use is for Model engineers. Instead of buying and milling a big block of steel, they could make an oversized model of what they plan to mill, print it out then mill the print to the correct dimensions, this may save them the huge cost of milling a big block of steel, over the cost of filler wire.
Just an idea, either way I see it as a pretty fun looking project and can't wait to see more.
