Patent number: 11914341Abstract: The invention relates to a computer-assisted method for generating a control data set for an additive layer manufacturing device. In a first step, a layer data set is accessed, wherein points are marked in the data model which correspond to an object cross-section and at which the bid-up material should be solidified. In a second step, the layer data set is modified in such a way that for at least a portion of the object cross-section, the number of beams required for solidifying the build-up material inside said portion is determined preferably automatically, according to quality specifications of the portion and/or a manufacturing time of the object. In a third step, the modified layer data set is provided as a control data set for the additive layer manufacturing device.Type: GrantFiled: March 7, 2018Date of Patent: February 27, 2024Assignee: EOS GmbH Electro Optical SystemsInventors: Martin Schade, Albert Fruth, Robert Achim Domröse, Maximilian Mittermüller, Michael Göth, Markus Kuchenbaur, Michael Kowal

Patent number: 11850661Abstract: Disclosed is a method for providing control data for an additive manufacturing device. The method includes accessing computer-based model data of a section of the object to be manufactured, defining a first portion and an adjoining second portion within the object section, and producing a data model of a region of a layer of the object section. Within the region a first portion cross-section cuts through the first portion and a second portion cross-section cuts through the second portion. An energy input parameter in the data model has, on average, a different value in the first portion cross-section than in the second portion cross-section and the energy beam is moved over the boundary of the first and second portion. Control data corresponding to the data model is provided for the generation of a control data set for the additive manufacturing device.Type: GrantFiled: August 2, 2018Date of Patent: December 26, 2023Assignee: EOS GmbH Electro Optical SystemsInventors: Michael Göth, Ludger Hümmeler, Alexander Bockstaller
