3D printers aren't material reassemblers. They replace milling and lathing when those methods take a day or more per part. You won't see it in your cupboard but rather a flight engineer might use it.
And yes, there is some use for such printers, but given their cost (and the cost per piece manufactured) they are limited to other very narrow and "rich" fields like aerospace.
