Most consumer 3D printers I've seen don't make especially smooth or detailed surfaces and the industrial ones that do are expensive...Also, there is the matter of creating and suitably refining a CAD model of the part.

Making a silicone mold is cheap, fast (ignoring mold and epoxy dry times, but you don't sit and watch it dry for a day like you might have to sit and tweak a cad model for hours) and accurate.

You can even make high-temperature silicone models that you can cast lead or pewter in...I've been considering doing that for a reproducing cracked pot metal parts for a Capehart turnover changer that I would like to eventually pair with my E.H Scott FM Philharmonic.
