My ProtoFlux “magnetic” filament arrived today on the cutest little (120mm) spool!
I was a Kickstarter backer, and my reward was this 1/2 pound spool of filament. I’ll have to figure out something cool to try it out with. I’m pretty sure by “magnetic”, they mean “can be picked up by a magnet.”
if it is not truly magnetic but can be picked up by a magnet i wonder if it is electrically conductive. I need a conductive filament for designing connector shrouds, if you have a dmm try measuring its resistance.
that would mean it is ferrous metal which means how would you melt it with a normal 3d printer hot end?
There are already filaments out there that are conductive just have higher resistances. Ferrous material is not the only conductive material a lot of times carbon is used.

Maybe not ferrous just very finely powdered ceramic magnetic material embedded in the PLAstic (pun intended)
@Tim_McDowell
Tested, and completely non-conductive at 0.5mm.
@Matthew_Battle_Libra
It probably contains some small amount of iron dust, but is mostly PLA. Even the very strong magnets I have attract to the filament only weakly. I’ll test again once I’ve printed something.
@Carlton_Dodd That would make more sense to how it would be magnetic.
In theory (!) if it’s some sort of ferromagnetic material you ought to be able to induce some level of permanent magnetization by exposing it to a really strong field.
@paul_wallich True, you could create an electromagnet!
