I haven’t used this resin yet. I’ll have stones in the pieces and I’ve modeled the setting to fit really well. With other processes such a molding or printing with a different printer, I’ve increased my model size slightly, say by 2-3.75% and it’s worked. Would I need to increase my model size using the castable wax and casting from it? I’d ask the caster, but it’s holidays and no one is in town right now.
