Specific metals? Better start with a whole lot of gold. There are 3d printers that can produce metal objects directly, but they're in a whole different price category from the ones discussed in this thread. EOS makes a nice one; I think you can pick one up for $800k or so. If you want to print the same part in different colors of metal at the same time, though, you're going to have to wait a while for the technology to catch up with your dreams. (That will give you time to save up...)
