Styrofoam can be cut or melted to vertually any shape
Give your answer to this question below!
I used to fabricate Vac Form molds for the defense industry, for models, using a 4 x 8 vac table.
My molds were all Maple, often laminated 2x whatever size, sanded, finished, and polished smooth to allow RELEASE after the fact.
The issue is ANY voids in whatever material you use that will allow the material to be contained into the voids in the vac process.
Without knowing what you’re actually attempting to form, the mold issue should be similar to fabricating a mold to lay up Fiberglass. Again,,,Release is the major issue.
