Method for the additive manufacturing of a component

Abstract

Method for the additive manufacturing of a component (2) by means of a manufacturing device (1) comprising: - a component holder (3) for receiving the component (2) to be manufactured, - a material feed device (8) by means of which a powdered material layer can be introduced into the component holder (3), - an active ingredient spray device (9) by means of which, in an area of ​​the powdered material layer to be fused, it can be wetted with a heat-conducting liquid, - an irradiation device (10) by means of which the powdered material layer can be irradiated, wherein, in the area of ​​its to be fused, wetted with the heat-conducting liquid, it can be transformed into a material-bonded component layer, - wherein the material feed device (8), the active ingredient spray device (9) and the irradiation device (10) together form a manufacturing module (11), - wherein the material feed device (8),The active ingredient spray device (9) and the irradiation device (10) are rotatable about a rotational axis (12) relative to the component holder (3); - wherein the material feed device (8), the active ingredient spray device (9) and the irradiation device (10) are movable parallel to the rotational axis (12) relative to the component holder (3), comprising the steps of: - introducing the powdered material layer into the component holder (3) by means of the material feed device (8); - wetting the area to be fused with the heat-conducting active liquid by means of the active ingredient spray device (9); - irradiating the powdered material layer, whereby it is transformed into a material-bonded component layer in the area to be fused, which is wetted with a first heat-conducting active liquid, by means of the irradiation device (10); - rotating the material feed device (8),the active ingredient spraying device (9) and the irradiation device (10) about the axis of rotation (12) relative to the component holder (3) by means of the manufacturing device (1);- moving the material feed device (8), the active ingredient spraying device (9) and the irradiation device (10) parallel to the axis of rotation (12) relative to the component holder (3) by means of the manufacturing device (1), wherein during a working cycle (S1) of the manufacturing device (1), as the manufacturing module (11) passes over the component holder (3), the material layer added during this working cycle (S1) is wetted with the first and a second heat-inhibiting active liquid, and the material layer wetted with the two active liquids during this working cycle (S1) is irradiated,and wherein, by means of the active ingredient spray device (9), in a non-melting area of ​​the powdered material layer, it can be wetted with an active liquid that inhibits heat conduction.
