Abstract
A powder dispensing assembly for an additive manufacturing machine includes a hopper defining a powder reservoir for receiving additive powder and a plurality of powder distribution modules operably coupled with the hopper. The powder distribution modules include a powder distribution body defining a discharge orifice and a supply gate that fluidly couples the powder reservoir to the discharge orifice. A plunger valve is movably mounted over the discharge orifice and an actuator moves the plunger valve between an open position and a closed position to selectively dispense a flow of additive powder.
