  • Patent number: 10830068
    Abstract: In a method for the generative production of a component (3), in particular of a turbo-engine component, wherein material (4) is bonded layer-by-layer selectively to a layer disposed therebeneath or to a substrate (6), according to the invention a laser (1A; 1B; 2) additionally acts on the material (4) before, during and/or after the bonding.
    Type: Grant
    Filed: October 13, 2012
    Date of Patent: November 10, 2020
    Assignee: MTU AERO ENGINES AG
    Inventors: Wilhelm Satzger, Siegfried Sikorski, Thomas Hess, Karl-Heinz Dusel, Hans-Christian Melzer
  • Patent number: 10633975
    Abstract: The invention relates to a device for producing, repairing and/or replacing a component, particularly an aircraft component, by means of a powder that can be solidified by energy radiation of an energy radiation source, characterized in that the device comprises an application unit that is designed such that the powder can be applied onto an uneven surface by means of the application unit.
    Type: Grant

  • Patent number: 9952236
    Abstract: Disclosed is a method for monitoring a generative fabrication process in which a component is formed in an installation space from a multiplicity of layers by using a three-dimensional data model and a following layer is fixed to a preceding layer by means of a high-energy beam. The method comprises detecting the component at least optically and detecting the installation space thermally during layer application. Also disclosed is a device for carrying out the method.

  • Publication number: 20130294891
    Abstract: The invention provides a method for the generative manufacture of a component (1) with integrated damping for a turbomachine, in particular a gas turbine, having the following method steps: building up the component (1) in a generative manner, and introducing a damping material (2) into the component (1) during the method step of the generative building up of the component (1). The invention further provides a component (1) with integrated damping for a turbomachine, in particular a gas turbine, wherein the component (1) is built up in a generative manner, and the component (1) has a damping material (2) which is introduced into the component (1) during the generative building up of the component (1). The invention further provides a turbomachine, in particular a gas turbine, comprising such a component (1).
