  • Patent number: 11835112
    Abstract: The invention relates to a two-axis rotator for producing a rotation about two orthogonal spatial axes, and to a handling device comprising a two-axis rotator of this kind. The two-axis rotator for producing a rotation about two mutually orthogonal rotational axes comprises a main body, a first rotor and a second rotor, wherein the first rotor is mounted on or in the main body so as to be able to rotate about a first rotational axis, and the second rotor is mounted on or in the first rotor so as to be able to rotate about a second rotational axis, and wherein the first rotor has a first drive and the second rotor has a second drive, and the first drive and the second drive can be driven independently of one another.

  • Publication number: 20230191497
    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.

  • Publication number: 20230191496
    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.
