PETG

Bringing PETG properties to metal composites! Made with real copper powder! Protopasta Composite Copper PETG is 60% copper by weight, like our original Copper-filled Metal Composite HTPLA. The main difference is you get PETG properties. Properties include: Metal finishes like cast (as printed), brushed/sanded, oxidized, or polished. Increased durability - filament bends without breaking Increased heat resistance compared to PLA Higher strength compared to PLA and HTPLA Less heat resistance than heat treated HTPLA Prints like PETG, but a lower nozzle temp can reduce stinging Density ~2x PETG (~1/2 length and volume compared to PETG) Visit our blog for more information.
