Magnetic Iron PLA

Proto-pasta Magnetic Iron PLA is a ferromagnetic material which behaves as pure iron––it even rusts for artistic effects! This material enables magnetically active projects, such as sensors or simple motors. Magnetic Iron PLA acts magnificently as a performance material, enabling a new frontier of creative projects and useful applications. A heated bed is not required for printing Magnetic Iron PLA, which has a unique metallic finish direct from the printer and can be polished to a shine. Perfect for robotic parts and jewelry as well!
