Are metal and conductive prints not exciting enough for you? Okay then, how about magnetic prints? This exotic 3D printer filament, based in PLA or ABS and infused with powdered iron, features a grainy, gunmetal finish, and of course, it sticks to magnets!
One thing to note: Despite the name, this 3D printer filament type is actually ferromagnetic, meaning that while it is attracted to magnetic fields, it has no fields of its own. In other words, the objects you print may stick to magnets, but they won’t actually be magnets.
When Should I Use Magnetic 3D Printer Filament?
Use this type of 3D printer filament whenever you want your prints to stick to something magnetic. Ornaments (especially for the fridge) are the most obvious example, but why not incorporate some magnetism into toys or tools?
