Proto-Pasta Magnetic Iron PLA 3mm

Proto-pasta Magnetic Iron PLA responds to magnets and behaves similarly to pure iron!  Wrapped in plastic, the iron maintains a stable matte, cast metal finish straight from your printer and can be rusted when desired.  Here is why Proto-pasta Iron PLA is so interesting:

1) Attracts magnets

2) PLA with less nozzle wear than Steel or Carbon Fiber


More thermally conductive than standard plastic
