I think that type of printer is geared for a much different market that the people we see here. I small business, Library or School who want a much more "hands off" approach to 3D Printing? Stratasys and 3D Systems have been doing it their way for decades! They try to limit the print issues by controlling what materials people use. As for Nylon, the Cube Pro is not ready for that yet, they are still be-bugging those units. I did hear at the show that they may be out of Beta Testing soon?
