said printers being motorized to allow movement thereof in any direction and to allow free rotation thereof over said electrically conductive surface;
each of said printers having one or more printheads and a plurality of brushes for electrically connecting to said electrically conductive surface for powering said printers;
said electrically conductive surface being independent from said printers and adapted to receive a printed object formed by said printers; and
said electrically conductive surface comprised of a plurality of electrically conductive islands surrounded by nonconductive areas comprised of perpendicularly extending grooves and channels, said islands comprised of alternating positive and negative conductive strips arranged over a nonconductive base, with a depth of said channels reaching down to said base and a depth of said grooves not reaching said base.
