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.
