1200C is just under 2200F, which you can get with a cheap pottery kiln. Here's one on Amazon for $530 https://www.amazon.com/dp/B01LYOCRSG/ref=cm_sw_r_cp_apa_i_I3XoDbQG7D500
The expensive ones go much hotter and have higher volume, but for this application, 2200F and a 6" cube internal space are all you will likely need.

Basically, It's a stopper that you can remove to look at the pottery without opening the lid and loosing the heat.
You will need a burnout oven if you have a resin printer I suggest using funtodo castable blend. They have instructions for a fast burn out I preheat my oven to 1600 and burnout for 2 hours. If your looking to do just one or two rings at a time I suggest you get a tabletop kiln like this or look on Ebay for a dental burnout oven the burnout equipment is the most expensive tool in the ring makeing process but you can't get around it.

Something like this would be perfect for you. And then just throw together a sand casting box.
There are also ones that are even cheaper that are meant for melting lead to cast muzzle loading shot or fishing sinkers. Those might work too for bronze if you're patient.
Regarding vacuum pumps, would it be something like this? https://www.riogrande.com/Product/RioVacuumTableforMoldMakingInvestingandCasting/705012
Like it would be used before you put the metal? or after?
Still looking for a good kiln, perhaps somthing like this to allow me to burn out my PLA and I think I could use this same device to melt my metal? https://www.amazon.com/Tabletop-Hi-Temp-Electric-Standard-Controller/dp/B07GWX18K9
Any thoughts?
