Article note: Ugh, the MIT hype machine is ridiculous even by modern academic standards.
The finding is that copper doped PLA filament exhibits PTC (positive temperature coefficient; resistance increases with temperature) properties, and they can make a resettable fuse. Which is neat but not terribly surprising since one of the common species of commercial PTC devices for use as resettable fuses is made from conductive particles in a polymer substrate.
The suggestion of active electronics is pure bullshit clickbait.
