Abstract: A printhead for 3D printing may include a first nozzle with a first opening configured for an extrusion of ink on a printing surface. The printhead may further include a second nozzle with a second opening configured for an extrusion of ink on the printing surface, where the first nozzle and the second nozzle are positioned to provide simultaneous extrusion of ink on the printing surface, and where a position of the first opening is independently movable relative to a position of the second opening.
