Abstract
A multi-nozzle extrusion printhead includes a chamber with an inlet to receive an extrusion material and a plurality of outlets fluidly coupled to the chamber. The printhead also includes a plurality of valves that control flow of extrusion material through the fluid outlets to nozzles in the printhead. Each valve includes a member and an electromechanical actuator configured to move the member to a first position to block a flow of the extrusion material through one of the fluid outlets and nozzles and to a second position to enable the flow of the extrusion material through the fluid outlet and nozzles.
