Claims10
A method of additive manufacturing comprising:
- moving a gate with respect to a powder dispenser to selectively dispense powder from the powder dispenser through the gate, the gate movable relative to movement of a recoater blade, wherein movement of the recoater blade spreads dispensed powder, wherein moving the gate includes selecting one of a multiple of apertures, at least one of the multiple of apertures different than at least one of the other apertures;
- and
- applying a laser to the dispensed powder.
A method of additive manufacturing comprising:
- moving a gate to selectively dispense one of a multiple of powders from a multi-powder dispenser, the gate movable with respect to a movement direction of a recoater blade, wherein movement of the recoater blade spreads dispensed powder, wherein moving the gate includes selecting one of a multiple of apertures, at least one of the multiple of apertures different than at least one of the other apertures;
- and
- applying a laser to the dispensed powder.
