Anyone who read science fiction back in the 1960s knows that the 4th dimension is time. Unless the produced objects enable time travel, they cannot be described as 4D.
These "4D" objects change across time.
Maybe the printer has a timer on it.
They do travel in time. Forward. Like the rest of us. ;-)

Only SF writers who don’t know anything about science. They should have read Flatland instead of A Wrinkle in Time.
We live in 3 spatial dimensions and 1 temporal dimension. A 4th spatial dimension would add another set of points (W,X,Y,Z) like the tesseract displayed earlier in the thread.
i thought 4 d was the power for one solid object to pass thru another.
Aha! If M-theory is right, there are 11 dimensions. Pick any four.
