Patents by Inventor Jürgen Ortmann

Jürgen Ortmann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods for the additive manufacture of components in layers, and corresponding computer program products
    Patent number: 11986995
    Abstract: The disclosure provides methods of additive manufacture of components in layers in a powder bed by at least two laser beams that can be deflected two-dimensionally over the same powder bed region. Each laser focal spot is projected onto the power bed and is or is set to a diameter of less than or equal to 300 ?m. Components to be produced in the powder bed region are manufactured by each of the laser beams, and each individual surface contour of the component is manufactured solely by one of the laser beams.
    Type: Grant

    Date of Patent: May 21, 2024
    Assignee: TRUMPF Laser- und Systemtechnik GmbH
    Inventors: Uwe Huber, Johannes Bauer, Michael Thielmann, Joachim Wagner, Jürgen Ortmann, Matthias Allenberg-Rabe, Detlef Breitling, Damien Buchbinder, Florian Krist
  • Calibrating a scanner device
    Patent number: 11899421
    Abstract: The present disclosure relates to calibrating scanner devices for positioning laser beams in a processing field, and includes, e.g.: arranging a retroreflector in the processing field of the scanner device, the processing field being formed in a processing chamber for irradiating powder layers; detecting laser radiation reflected back into the scanner device when the laser beam passes over the retroreflector; determining an actual position of the laser beam in the processing field using the detected laser radiation; and calibrating the scanner device by correcting a laser beam target position specified for the scanner device in the processing field using the determined actual position of the laser beam in the processing field.
