printing significant undercuts without support?

For some reason I cant get my brain wrapped around this concept. Would it be possible to print parts with significant undercuts without support by setting the entire printer at a 45 degree angle? You'd have to be aware how the part is plated, and not all parts could be printed this way, but some could, no?

It might be easier to rotate the part appropriately.

The BlackBelt system puts the Z-axis at a 45 degree angle:

Mainly to allow for an infinite Y-axis, but at the same time it is said to be able to make longer overhangs.

More to the point perhaps: there are systems that rotate the print bed. It is called 5-axis printing:

(watch the videos, it looks amazing :D)
