  • Focus adjustment and laser beam caustic estimation via frequency analysis of time traces and 2D raster scan data
    Patent number: 11878365
    Abstract: Methods of determining at least one parameter of an irradiation device of an apparatus for additively manufacturing three-dimensional objects may include generating an energy beam and guiding the energy beam across a structured test surface, generating a signal by detecting radiation that is emitted from the test surface, and determining the at least one parameter based on a frequency spectrum of the signal.
    Type: Grant
    Filed: November 20, 2019
    Date of Patent: January 23, 2024
    Assignee: Concept Laser GmbH
    Inventors: Christian Dicken, Ann-Kathrin Kleinschmidt, Tim Klaussner, Bertram Gaerber
  • Method for determining an operational parameter for an imaging device
    Patent number: 11548230
    Abstract: Method for determining an operational parameter for an imaging device for imaging at least one part of a build plane, in particular for a determination device for determining at least one parameter of an energy beam for an apparatus for additively manufacturing three-dimensional objects, comprising the steps: determining at least one spot parameter that relates to an extension of a spot, in particular a spot of an energy beam, in a determination plane; determining a difference between the determined spot parameter and a nominal spot parameter; determining an imaging parameter of the imaging device based on the determined difference adjusting the imaging parameter based on the determined difference.
