Abstract: A method of applying a plurality of energy beams in the additive manufacture of a component includes a) providing a first and a second energy beam, each set up for the irradiation of a layer of a powder bed, wherein the first beam scans over a first irradiation area and the second beam scans over a second irradiation area, wherein the first and second irradiation areas are substantially arranged adjacent to each other and form part of a manufacturing plane, and b) assigning a scan vector to be scanned in the first irradiation area by the second energy beam, when a melt pool generated by the second energy beam during the scan of the vector is expected to cause less overlap with a powder bed outside of the component's geometry than a melt pool generated by the first energy beam would cause during the scan of the vector.

Abstract: A method for selectively irradiating a powder layer in additive manufacturing of a component. The method including: determining an irradiation pattern of the layer for additive manufacturing, wherein a first partial pattern is defined which is intended for continuous irradiation and comprises a plurality of irradiation vectors and wherein a second partial pattern is defined, which is intended for a pulsed irradiation, with the first and the second partial pattern being selected in such a manner that the second partial pattern connects irradiation vectors of the first partial pattern, and irradiating the layer in accordance with the irradiation patterns defined. A computer program product, an irradiating device, and a control unit for controlling an irradiating device are included.

Abstract: The invention refers to a method for selective laser melting additive manufacturing a three-dimensional metallic or ceramic article/component entirely or partly. The method includes successively building up said article/component layer by layer directly from a powder bed of a metallic or ceramic base material by means of remelting the layers with a high energy laser beam, moving repetitively across the areas, which are to be solidified. The movement of the laser beam is made of a superposition of a continuous linear movement and at least one superimposed oscillation with a determined frequency and amplitude. The oscillation is created by a beam deflection device and the same beam deflection device is also used for linear positioning movement.

Abstract: The invention refers to a method for manufacturing a hybrid component including the following steps of manufacturing a preform as a first part of the hybrid component, then successively building up on that preform a second part of the component from a metallic powder material by means of an additive manufacturing process by scanning with an energy beam, thereby establishing a controlled grain orientation in primary and in secondary direction of at least a part of the second part of the component. The controlled secondary grain orientation is realized by applying a specific scanning pattern of the energy beam, which is aligned to the cross section profile of the component or to the local load conditions for the component.

Abstract: The invention refers to a method for manufacturing a three-dimensional metallic article/component made of a Ni-, Co-, Fe-based superalloy or combinations thereof, entirely or partly, by a powder based additive manufacturing process. During the step of performing powder melting by scanning a dual laser setup is used, where two laser beams of different beam properties are combined in the same machine and by adjusted beam profiling and integration of a suitable beam switch in a controlled manner a switching between two different laser beam diameters is performed. In each layer the laser beam with the smaller diameter scans the whole area and in every kth layer, with k>1, the laser beam with the larger diameter scans the area where a coarse grain size is needed thereby remelting the area with fine grain sizes. With such a manufacturing method higher lifetime and operation performances of metallic parts and prototypes can be reached.
