Iron-filled Metal Composite PLA

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)

We recommend experimenting with creating a rusty patina like this:

 **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.

  • Available in 1.75 & 2.85 (3) mm diameters.
  • 125g are loose coils, 500g is on a 8" diameter spool, 2kg is on a 12" diameter spool.
  • Usable on most PLA-compatible printers, such as Lulzbot, Makerbot, FlashForge, Dremel, Ultimaker, Printrbot, and more!

In filament form, FEPLA is slightly more brittle than standard PLA, and requires extra care when handling. 

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.

magnetic filament

I have to proof which nozzle and bed temperature was the best. after 5 trials i discover that a nozzle temp of 205 and a bed temperature of 60 was perfect. think that the recommend temp should be a little narrower. Of course that a filament flow of 130 help a lot. I am not an expert, just a rookie but this is my experience with your filament

Quite a surprising material - very impressed!

The PLA rusts perfectly with a little bit of "rusting solution" (Hydrogen Peroxide, Salt, White Vinegar). Spray and let it dry - very impressive results. Product is brittle - as noted - so you have to be a bit more gentle with it. I'll get used to the cardboard spool. Initially it bothered me, because it dod not roll nicely on my filament spool roller, but in the end it worked fine. I appreciate the reduction in plastic. All in all, a 4.9/5. Would buy again.

Prints great!

This is a great filament material. Even on the least amount of infill for my printer I'm able to stick ferrite magnets to it. I found it was necessary to rig up a "tall" spool holder to keep the filament as straight as possible heading to the extruder and it's allowed me to be able to produce some very large, fantastic looking parts with this stuff!

Best metal fill out there

I've used the iron and the bronze and you cannot beat proto post for metal fill. they have the highest percentage of metal to pla available. If you're running an all metal hot end, you do need to run it at about 230-240c and i wish that info was more readily available or on the package. great product though
