Zusammenfassung:A dosing feeder for a powder-fusing apparatus that includes a powder inlet that is configured to receive powder from a discharge opening of a powder bunker, a powder outlet that is configured to release powder to a recoater reservoir of the powder fusion apparatus, and a powder support that is located in between the powder inlet and the powder outlet and that is configured to convey powder from the powder inlet to the powder outlet. The dosing feeder enables dosing of the powder transferred from the powder bunker to the recoater reservoir with high precision if the powder support is coupled to an ultrasonic transmitter and/or to a vibrational drive.
