As long as 3d printers are less than 50% harder to use than normal printers, they're dimensionally easier per capita.

Incidentally, almost all color 2D printers insert serial number tracing artifacts, and many 2D scanners and photo editing software prevent manipulation of images containing either EURion constellation circles or Counterfeit Deterrence System patterns. Interestingly, I didn't have a problem downloading, manipulating, or attempting to print currency-detected fragment images on iPadOS 18.x.
