We haven't finalized our policy on this yet. In principle, we aren't opposed to selling parts for people to repair their own printers, but with high-volume products designed to minimize cost, certain repairs may end up requiring more specialized expertise. (We really don't want to be be receiving partially disassembled printers in our repair department.) Certainly some spare parts (like the removable build table) will be available for sale, but we'll be evaluating on a part-by-part basis exactly which parts will be available for user repair.
