Claim 5:
6. A powder dispensing assembly for an additive manufacturing machine, the powder dispensing assembly comprising:
a housing that defines a powder reservoir that receives additive powder;
a first plate removably connected to the housing, the first plate defining a first discharge orifice having a first discharge orifice geometry and a second discharge orifice having a second discharge orifice geometry different than the first discharge orifice geometry;
a first gate in communication with the first discharge orifice, the first gate transitionable between a first open position in which the additive powder flows through the first discharge orifice and a first closed position in which the first discharge orifice is closed; and
a second gate in communication with the second discharge orifice, the second gate transitionable between a second open position in which the additive powder flows through the second discharge orifice and a second closed position in which the second discharge orifice is closed,
wherein the additive powder flows out of the first discharge orifice at a first dosing rate and the additive powder flows out of the second discharge orifice at a second dosing rate different than the first dosing rate.
