US2020307103A1
APPARATUS FOR ADDITIVELY MANUFACTURING THREE-DIMENSIONAL OBJECTS
Publication/Patent Number: US2020307103A1 Publication Date: 2020-10-01 Application Number: 16/832,331 Filing Date: 2020-03-27 Inventor: Junge, Jens   Scherr, Mariatheresia   Hunze, Stephan   Assignee: Concept Laser GmbH   IPC: B29C64/393 Abstract: An apparatus for additively manufacturing three-dimensional objects formed of selective consolidation of layers of a build material is provided. The apparatus may include a determination device configured to determine at least one parameter of the energy beam, wherein the determination device comprises at least one determination base body arranged in a beam guiding plane, wherein at least one surface parameter of a surface of the determination base body is defined dependent on a surface parameter of a specific build material arranged in a build plane in an additive manufacturing process performed on the apparatus. Determination devices and methods are also generally provided for determining at least one parameter of an energy beam of an apparatus for additively manufacturing three-dimensional objects.

APPARATUS FOR ADDITIVELY MANUFACTURING THREE-DIMENSIONAL OBJECTS
Publication/Patent Number: US2020307104A1 Publication Date: 2020-10-01 Application Number: 16/832,371 Filing Date: 2020-03-27 Inventor: Hunze, Stephan   Junge, Jens   Scherr, Mariatheresia   Assignee: Concept Laser GmbH   IPC: B29C64/393 Abstract: An apparatus for additively manufacturing three-dimensional objects formed of successive layerwise consolidation of layers of a build material which can be consolidated by an energy beam. The apparatus may include a determination device confirmed to determine at least one parameter of the energy beam for a specific build material, wherein the determination device comprises at least one determination base body arrangeable or arranged in a beam guiding plane, in particular a build plane; and a tempering unit confirmed to temper the determination base body. Determination devices, along with methods, are also provided for determining at least one parameter of an energy beam of an apparatus for additively manufacturing three-dimensional objects.
