"Lamination" doesn't always need to use heat, but when it doesn't it then it uses pressure. Also not very good for flower petals. "Filament" is a string of something that's usually melted, though. Looking at durandium, it seems to have likely been chosen because it has a very thin alloy base unit (along with the rule of cool).
Maybe instead of "laminated in a Transparent Durandium filament" it could be "coated with a monomolecular latticework bonding made of Transparent Durandium." Or something. Just an idea to maintain the original intent.
