[Oliver Tolar] and [Denis Herrmann], two students from the Zurich University of Applied Sciences (ZHAW), designed and produced a 3D printer prototype that has a movable printing bed that can tilt. By tilting, objects with critical overhangs can be printed…

Better hope they have good bed adhesion =)

I have no doubt that in time, support in FDM printing will be all but eliminated due to multi-axis (more than the x/y/z) printing systems becoming mainstream. The math isn’t that difficult by today’s standards. It’ll happen, this and multi-material printing will be some of the next big moves in the coming years in the FDM world (I think).
@jerryflyguy and then you just waste the effort with a combinator-multicolor print and a waste tower 
Genius idea! Kudos!
@Anton_Fosselius a purge tower is a different beast than support. Purge towers are already a thing, while removing the need to support would be a step forward. Who knows maybe hotends can be refined to the point where the purge tower is tiny compared to today’s large blocks.
That might get me to start watching my printer print and getting hypnotized again. 
That would be a nightmare for bed leveling XP
@Baruch_Torres depends, if a grid was measured using a sensor and then compensated using the bed tilt… might make it easier? No question multi-axis motion is more complicated and difficult than the typical 3axis we know today. If it was easy, it’d already be mainstream
Interesting idea, but this design almost doubles the amount of motors you need. It is effectively an hour glass delta printer. And ya, bed adhesion may be an issue. I bought my Delta, because i didn’t like my part moving around while being printed. i would love to see one of these in person, maybe even a shoot out with some well known deltas on the market.
