Metal 3-D Printer v1.0

The Metal Delta RepRap v1 uses a upside down Rostock-like stage to move a substrate under a MIG welder. We have demonstrated steel printing using standard welding wire. For details see: G.C.

[How to build, BOM, Instructions](http://www.appropedia.org/Open-source_metal_3-D_printer) - the build is pretty easy by RepRap standards - less than a day when you have the full BOM. Total cost, including the welder is
