3D printing is fascinating and very handy for hobby construction as well, a friend gave me a half built Prusa Mendel which i would love to finish at some point, printing metals would be an amazing ability, but i have not seen a hobby build that does that yet, mainly plastics and wood compound extrusion.

I wonder what kind of resistivity they can get with the silver nano particle ink compared to 1 ounce or 2 ounce copper foil? Any info on that floating around?
