At least one of the beta sites is guaranteed to give it a good workout. The Art Center College of Design in Pasadena, California has been using a variety of additive fabrication systems for some time and has wide experience with 3D printing. I know that Michael Berman and the rest of the faculty have been excited about the potential of the Desktop Factory for their students.
I'm extremely jealous!!
We now have both of the latest low-cost commercial desktop 3D printers now in beta which puts us one step closer to having them on our own desks!
