摘要： The invention provides a method for determining a scanning speed of a high-energy beam of a manufacturing device for the additive production of a component, in particular a component of a turbomachine, comprising the steps of guiding of the high-energy beam, which is generated by a radiation source of the manufacturing device, over a surface; detection of the path, irradiated during a predetermined period of time with the high-energy beam, on the surface, by recording respective brightness values on the surface by a detection device during the predetermined period of time; calculation of the scanning speed as a function of the predetermined period of time and of the detected irradiated path by an analysis device. The invention further relates to a method for operating a manufacturing device and to a manufacturing device for the additive production of a component of a turbomachine.

摘要： The invention relates to a layer building process for the additive manufacture of at least one wall region of a component including applying at least one powder layer of a material to at least one building-up and joining zone of at least one movable building platform, carrying out a first solidifying step, in which the material is irradiated selectively with at least one energy beam, wherein irradiation parameters of the at least one energy beam are set so a molten bath is produced and a defect-affected wall region of the wall is produced, without applying a further powder layer, carrying out a second solidifying step, in which the defect-affected wall region produced in the first solidifying step is irradiated selectively with the at least one energy beam, lowering the building platform layer by layer by a predefined layer thickness, and repeating the steps above one or more times.

摘要： The invention relates to a method for determining individual vectors for open-loop and/or closed-loop control of at least one energy beam of a layering apparatus, comprising at least the steps of: providing layer data characterizing at least one component layer of a component to be additively manufactured, on the basis of the layer data, determining individual vectors, according to which at least one energy beam is to be moved relative to a construction and joining zone of the layering apparatus in order to solidify a material powder selectively to the component layer, determining at least one node point of a plurality of individual vectors, and adapting at least one property of at least one individual vector of the at least one node point, the at least one property being selected from a group comprising spatial orientation, radiation sequence in relation to at least one other individual vector, and vector length.

摘要： The layer construction method comprises at least the following steps: a) applying at least one powder layer of a material to at least one construction and joining zone of at least one movable construction platform; b) locally solidifying the material to form a component layer, wherein the material is selectively scanned along scan lines by at least one energy beam and fused; c) lowering the construction platform layer by layer by a predefined layer thickness; and d) repeating the steps a) to c) until the component region is complete.
In step b), a distance hs between at least two central lines of neighboring scan lines in at least one component layer is adjusted in accordance with Formula I 0.85≤bsmin/hs≤1.00 (I) wherein bsmin represents a minimum melt pool width of the scan lines.-
