First I hear of Project Binky but this might be one of those "because they can" projects. This is quite ingenious though, hat off! And btw, this does harken back to the heyday of the 3D-printing hype where they hypists were saying that we would "soon" 3D-print entire electronic devices. That never materialized, of course. Maybe that was one inspiration. Afaik, this seems like it's probably the easiest way of metal 3d printing at home - I wonder whether that's the more interesting thing about this achievement. I don't really know much about in-and-out of melting metals, toxicity and so on but there are some lower melting metals like zinc at 420*C which could be reached with a 3D printing hotend with a resistive cartridge and copper block I think. That would be rather intersting.
