Here are some more of the cool things they had:
Yes, that is a plastic chain link that really works!

I would love to hear about how schools are incorporating 3D printer technology into their classes. I would like to try and get one for our school next year, but I worry about the technicalities. How difficult are the printers to get set up? How difficult is the software to learn how to use? What kind of creation software is being used the most? The guy that was demonstrating this explained how students don't even need to design their own things, they can simply use thingiverse.com to find designs that others have already created. But, I would prefer our students to design their own things. Right now, our technology classes use Sketchup to make computer designs, but I know there is probably something better.
