I’m making some turians! These are a little different from how Garrus was done; the face plates and mandibles are cast resin pieces rather than latex, but the overall principle is similar.
Since I decided to mold and cast my female turian mask using resin, rather than using latex like I did with Garrus, I wanted to do a quick write-up to show some of the differences.
Casting with latex (a soft material) is done with a hard, porous mold, usually made from plaster of some kind. Casting resin (a hard material) requires a soft, non-porous mold, in this case made from silicone.
