Whether or not it is newsworthy… eh, I mean, what is MIT News? A campus newspaper? I’m pretty sure we had articles on particularly big games of capture the flag in mine.
It looks like the editors have amended the title of their article since this was initially posted. The original title was just “3D-printed Active Electronics”
What seems cool about this to me is that they seem to have done it with a plain old FDM printer and copper impregnated PLA. The devices are fairly large (mm scale) so presumably anyone with a $200 ender and the correct filament could print these.
I am able to find copper PLA for sale too, although I'm not positive it is what was used in the experiment, and it's kind of pricey (~ $100/kg).
