We have had a 3D printer in the Learning Studio for a few months, and some of us have been experimenting with ways to use it meaningfully, whether it is to make custom parts for exhibits on the floor, or cool materials that bend and spring in interesting ways. For me, though, the whole process lacked a certain crucial degree of appeal. I don't know how to use a 3D cad program, and although I am interested in learning eventually, the learning curve is quite steep and the process very long before I can get something meaningful out of it.
