More metal + heat resistance!
High Density Iron HTPLA Filament has 60wt% iron for 3D prints with 2x the magnetic force and 3x the temperature resistance (when heat treated) compared to Protopasta's original Iron PLA with 45wt% iron.
Protopasta Iron HTPLA is ferromagnetic. It responds to magnets and behaves similarly to pure iron! Encapsulated in plastic, the iron maintains a stable matte, cast-metal finish as printed, but can be rusted when desired.
