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

Prints like PLA, behaves like metal! Experience our ost "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)
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.

This material has been flow optimized and has less moisture uptake than standard PLAs, however composites are still sometimes more tricky to print depending on hardware and software settings. The main challenge is to keep mass flow up (larger nozzle + fast speed) and in a single direction (minimal retraction) to avoid heat soak. More on that topic here.
This filament works great! The layers coke out suuuuuuuuuper flat, and the first layer stuck with no problems. One thing to consider when printing that I noticed is that bridging and overhangs sometimes don’t stick well unless you go super slow. My only other grievance with it is that I’ve noticed is that the filament is a bit brittle and while normally it’s good, occasionally cracks when trying to unload the filament and store it. Once printed, however, it is very stiff and performs great. When printing with a lot of retraction, it also has very little stringing opposed to other filaments I’ve used.
This is my favorite filament. Here is a Shrine of Talos (from the video game TES V: Skyrim) that I modeled in Blender and then printed with Protopasta's iron-infused filament. (The interior is regular PLA, as were the supports). Then I artificially rusted it using a combination of hydrogen peroxide and salt. Sometimes I also use vinegar, but I find that promotes a deeper rust, while just peroxide and salt generate a more shallow coating of rust.
