As a 3D printing dude - right now the main emphasis is either hobbyists can DIY print stuff at home (since they couldn't do that before) or you can use 3D printers to make really crazy geometries that aren't possible - think of nuts lattice-work. Here's group that have amazing algorithmic 3DP art: http://n-e-r-v-o-u-s.com http://n-e-r-v-o-u-s.com Other practical uses are like InvisAlign mouthpieces that are each 3D printed to your specific teeth. It would've been possible using CNC, but would have been very hard to do.
