Foundation as a series is already somewhat uneven and less than “pure.” Asimov pulled a Lucas and cluttered it with sequels and prequels that muddled it with connections to his robot novels. Then there’s the additional books by other writers. And if you want to get real picky, Second Foundation gets real pseudoscientific with the pseudo-psionics compared to the first two books.
The hype cycle of 3D printers has probably plateaued into productivity now. Certainly the Maker movement is alive and well but it's not the hot new thing like it was a decade or a dozen years ago. Makerspaces aren't sprouting like mushrooms like they were before (partly because critical mass was already reached, partly because the pandemic reduction of physicality I'd guess), you don't see gimmicky 3D-printing kiosks at the mall anymore.
