Reading the article, it looks like so far they only have a working resettable fuse (a passive device), and only hypothesize that a transistor was possible with the copper-infused PLA filament. So no actual working active electronics.

And from the paper linked in the article[1], it seems the actual breakthrough is the discovery that copper-infused PLA filament exhibits a PTC-effect, which is noteworthy, but definitely not "3D-Printed Active Electronics" newsworthy.

Not to be that guy, but this is a typical situation as it occurs a thousand times per week:

1. Scientists make minor progress as part of a multi-year effort, release a paper, paper features overly optimistic outlook to get future funding

2. Institute marketing department both hypes it up and dumbs it down a little

3. Popular science press picks it up and both hypes it up and dumbs it down a little more

4. Scientific literate readers read it and complain

TL;DR: Nothing new under the sun
