Topic: Crazy thought
im not sure how well this would work but let me start off with sometimes i have wierd ideas
most 3d printers work in a temperature range of up to 280c or 536f
(i do not know how to make the degree symbol)
most solder will melt at about 500f and i'm not even sure you would want it to be molten or plastic but is it possable you could get a printer that would make metal parts? usign say a solidoodle with a form of solder filament? or would there be another form of metal filament that woudl work better? if so what would it be?
From my research there are a few that might work or posaably a few that as an alloy may work
tin
bismuth
cadmium but it is poisonous
pewter
lead poisonous
So you would want an alloy that would be plastic around 500f not that doesn't have lead or cadmium
