Is this for use in vacuum casting where the porous investment allows air to escape under vacuum as the molten metal is being poured in?

Yes, produces good detail, I'm using for Brass.

Can you suggest oro or optima for casting 3d printed resins using 21k yellow gold?

The Optima investment will work great for wax models, however, it is specifically designed for use with the higher temperatures required for the resin burnouts. Thank you!
