There is probably a number of different routes you can try here. You may
also want to try making the mould directly by one of the rp processes. 400F
is not too high so I suspect you could cast pewter into almost all rp
cavities (e.g. SL, SLS, FDM, LOM, ZCorp etc.). We have recently injection
moulded PEEK (which has a melting temperature of 400C) into SL cavities so
400F should be okay.

Good luck.

One way to utilize rapid prototyping for your needs is to cast a silicone
rubber mold from a well finished rp master, then cast up to 30 or more
ceramic duplicates in the rubber mold. It's an extra step to get one pewter
figure, but a good way to make multiple figures.
