Can this be done.

my mold would be a sandwich of materials with tiles on the outside where I would etch my copy/images. The center layer could be Masonite or something.

so I need a material that can stand up to 575 degrees Fahrenheit.
i need to laser it deep enough that the pewter image will show but not so deep that the metal won’t release.

these are for Christmas ornaments for my grandsons preschool.

i only need to cast 15 parts. I could make 15 single-use mdf molds.but that seems wrong to me.
