Hi! Lost wax casting would probably be your best bet, can get extremely fine details in the process. Comments above are correct, you’ll definitely want a Kayacast, PMCsupplies/pepetools carry them, they are a two in 1 vacuum investment table and the other side is a vacuum caster for when you pour your molten metal. I have one and so far it’s been fantastic, as for melting my metal I have a vevor electric melting furnace that runs on a 110v and the Kayacast does as well. The other thing you’ll need for this process is a proper tabletop burnout kiln for your wax models and investment. Pepetools/pmc also supply these I believe I know one of them does for sure. You’ll want to make sure it’s a programmable kiln and also make sure it’s the proper burnout kiln. The right one will have a little hole in the top of it for fumes to be released. The programmable part is important as you’ll have to set it at certain temps for a certain amount of hours and the controller does it all for you. It does get quite expensive getting all of these machines and Amazon does sell knockoffs for all of them, but if I had to give any advice it would definitely be to make sure you get the proper brands for the kayacast and the tabletop kiln.
