摘要： 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.

摘要： An apparatus for producing a three-dimensional work piece is provided. The apparatus comprises an irradiation unit comprising at least one scanning unit configured to scan a radiation beam over an uppermost layer of raw material powder to predetermined sites of the uppermost layer of the raw material powder in order to solidify the raw material powder at the predetermined sites. An axis corresponding to the radiation beam when it impinges on the uppermost layer of raw material powder at an angle of 90° is defined as a central axis for the scanning unit. The apparatus further comprises a control unit configured to receive work piece data indicative of at least one layer of the three-dimensional work piece to be produced, and assign at least a part of a contour of the layer of the three-dimensional work piece to the at least one scanning unit. According to a first aspect, the control unit is configured to generate control data for controlling the irradiation unit, the control data defining a scan strategy of the radiation beam such that for more than 50% of a predefined length, the radiation beam moves away from the central axis, the predefined length being defined as a length the radiation beam moves along the contour assigned to the at least one scanning unit, excluding sections concentric with regard to the central axis. Further, corresponding methods and computer program products are provided.

摘要： In a method for manufacturing a component containing an iron alloy material, a pulverulent pre-alloy is provided. The pre-alloy comprises, in wt. %, 0.01 to 1% C, 0.0.01 to 30% Mn, ≤6% Al, and 0.05 to 6.0% Si, the remainder being Fe and usual contaminants. The pulverulent pre-alloy is mixed with at least one of elementary Ag powder, elementary Au powder, elementary Pd powder and elementary Pt powder so as to produce a powder mixture containing 0.1 to 20% of at least one of Ag, Au, Pd and Pt. The powder mixture is applied onto a carrier (16) by means of a powder application device (14). Electromagnetic or particle radiation is selectively irradiated onto the powder mixture applied onto the carrier (16) by means of an irradiation device (18) so as to generate a component from the powder mixture by an additive layer construction method.
