Magnetic Iron PLA for 3D Printing Printer Material by Proto-Pasta Canada


Magnetic Iron PLA - 2.85mm
Free Gift


Prints like PLA, behaves like metal! Experience our most "attractive" material yet!!!

Proto-pasta Rustable Magnetic Iron Metal PLA Composite is actually 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.  Here is why Proto-pasta Iron PLA is so interesting:

  • Weighted feel with 1.5x the density of standard PLA
  • Rustable to create modern artifacts in a few easy steps - instruction here
  • Attracts magnets (neodymium type recommended for strongest attraction)
    • Induction at magnetic saturation about 0.15 Tesla
    • Relative (to air) Permeability - between 5 and 8 independent of frequency up to 1 MHz
    • Permeability - between 62E-7 and 100E-7 H/m independent of frequency up to 1 MHz
  • More thermally conductive than standard plastic
  • Prints easily like PLA with less nozzle wear than Steel or Carbon Fiber
  • More filament for your money - 2x the length of Bronzefill (500g Iron =1kg Bronzefill)

    To get a rusty look, "polish" your finished print with a wire brush to expose more of the iron particles to the air. Then, submerge the piece in a salty solution for about 2-3 days. You can soak longer if you would like a more very rusty finish. 

    STORAGE: One large resealable bag with slider + an extra desiccant pack are included with every spool. The bag and extra desiccant are a great way to safely store your filament spool when not in use. It keeps your filament bone dry & free from any dust or dirt particles, so it's always ready for your next print.

    • Processing is comparable to standard PLA. No heated bed required. Process may be less consistent on smaller nozzles and/or bowden type machines.  We frequently print using direct-drive systems with 0.4 mm nozzles, though prefer 0.6 mm and 190-210C (standard PLA or a bit cooler) for the best experience.

    • This filament is more abrasive than standard PLA. Be prepared to replace your nozzle and do 1st layer adjustment. Try a wear resistant and/or larger diameter nozzle for increased service intervals.
    • In filament form, FEPLA is slightly more brittle than standard PLA, and requires extra care when handling.
