Another option is to buy a SLA or DLP printer and use a burn-away (AKA clean-burn, aka investment casting) resin to make a metal casting. It's the preferred method for making printed metal jewelry, though it does require you to get your hands a bit dirty and use some traditional casting methods.

Also, right now, burn-away photoresin is silly expensive (not as expensive as a metal SLS printer though.)

By far the cheapest option though is to kludge together a heated paste extruder to an FFF printer to print with layers of hot wax, then use the printed part to make a lost-wax casting...
