@Bass: It might be easier to print structures that can withstand 1/6 earth normal gravity, but yeah, 3D printing in general is spectacular.

It might be 1/6 less gravity, but it does have high energy radiation and micro-asteroids to deal with., so I'm not sure it's all that much easier than building stuff on Earth.

The cool thing about NASA being interested in it is it puts some serious research and funding into 3D printing which will make having star-trek-esque replicators that much closer to reality here on Earth.
