our university has a pretty nice 3D printer that uses powder and binder. The printing area is about 12 *12 inches and does colours too.
We've created functional bearings for fun but most importantly we're creating structural models for proteins, drugs, and chemicals for visual and tactile representations for use in class. (i'll get some photos if someone's interested) Only bad thing of this printer is that it's much more fragile compared to PVC and needs to be manually waxed to make it shiny.
personally i'd get reprap and make fan grills out of clear plastic.
