As a member of one of the biggest groups of Rep Rap members(in the thousands) I find patents really important. Patents forbid you selling anything, even with no profit. Lots of pieces need to be sold for making 3D printers accessible for all. The electronics controlling board, the hotends, the friction wheels. Most of the general population can't fabricate those things, but they want to use 3d printing anyway, like most women(90%of reprap now is men) don't know(or care) what a fuel injector is but they want a car for going to work. In the future it is about Inkjet cartridges, wax and ceramic binders.
