Proto-Pasta's Magnetic Iron PLA is truly one of a kind! Like pure Iron, this filament is attracted to magnetic fields. Translation: magnets stick to it! It also rusts like real iron. To get a rusty iron look, "polish" your finished print with a wire brush to expose more of the iron particles to the air. Then, submerge print in a salty solution for about 2-3 days. Soak for a longer period to achieve a rustier finish.

Nice Magnetism!
