For my senior project we were tasked with building a 3D printer which could print both plastic and a metal of some sort. After much research, we settled on a low melting point allow of Bismuth and Tin. Indium added to the alloy would likely dramatically improve printability, however we could not source a manufacturer. We are using a stock E3D V6 with a smaller Teflon sleeve added to for the 1.22mm 'filament'. The alloy is Sn42/Bi58. It seems to like settings similar to printing with PLA. In this case the heated bed was set to 60*, and the extruder to 190*.
