3D Printing Systems published an awesome job they have done recently by printing out a quadruple bearing that rotates on each other. It is made at 150 micron / 0.15mm per layer on an UP Plus 3D printer.
This awesome design made by idea_beans on Thingiverse is based on her earlier design "Spinning Double Ball Bearings". With this design you can just print everything in one go, and then remove the raft and supports.
Earlier last year 3D Printing Systems made another "The Impossible 3D Print" which is inspired by an old wooden direction reversing mechanism from a 1936 series of engineering books called "Ingenious mechanisms for designers and inventors". The CAD model is designed by Olaf Diegel.
It is printed at 0.2mm on the UP Plus 3D Printer and the total print time is 13 hours. Approx cost is $7.6 only. It took quite a lot of work to clean supports, maybe it would be easier if the supporting material was water soluble so you could just dissolve it away.
These are nice examples to show how you can print moving parts in one print. Watch the video below:

can this be created with magnetic material?
