Abstract: A planning device for planning locally selective irradiation of a work region using an energy beam in order to produce a component from a powder material arranged in the work region is provided. The planning device is configured to obtain a plurality of irradiation vectors for irradiating a powder material layer arranged in the work region with the energy beam. The planning device is further configured to determine a vector alignment in a coordinate system on the work region for at least one irradiation vector of the plurality of irradiation vectors, and to specify, for the at least one irradiation vector, a beam alignment for a non-circular beam shape of the energy beam on the work region relative to the vector alignment of the at least one irradiation vector.

Abstract: A method for planning locally selective irradiation of a working region with an energy beam in order to produce a component from a powder material arranged in the working region includes defining an origin on a component contour of a component layer to be generated on a powder material layer in the working region, and overlaying the component contour, based on the origin, with an arrangement of irradiation regions to be irradiated with the energy beam. Each irradiation region has a dimension that is predetermined independently of the component contour and identical for all irradiation regions.

Abstract: A manufacturing device for additive manufacture of components includes a beam generation device configured to generate energy beams, a scanner device configured to locally and selectively irradiate a working region with the energy beams, a protective gas device configured to generate a protective gas flow over the working region, and a control device configured to drive the scanner device. The control device is configured to define a first irradiation region along which a first irradiation section is displaced from a first starting position to a first end position, to define a second irradiation region along which a second irradiation section is displaced from a second starting position to a second end position, and to begin irradiation of the second irradiation region when the first irradiation section and the second starting position are not arranged within an interaction zone defined by a protective gas flow direction relative to one another.
