METHOD AND SYSTEM FOR DELIVERING BUILDING MATERIAL TO A PRINTING HEAD

Abstract: a system for delivering liquid material to a nozzle array of a printing system comprises a cartridge and a vented sub-tank. the cartridge has a cartridge outlet and contains the liquid material. the sub-tank has a sub-tank inlet configured to receive the cartridge outlet to allow the liquid material to flow through the cartridge outlet by gravity, two inlet ports within the sub-tank inlet at different heights relative to a liquid level in the sub-tank, and a sub-tank outlet. the sub-tank outlet is sealingly connectable to the nozzle array by a pipe and has an outlet port below the inlet ports.
