EP3715019A1
APPARATUS FOR ADDITIVELY MANUFACTURING THREE-DIMENSIONAL OBJECTS
Publication/Patent Number: EP3715019A1 Publication Date: 2020-09-30 Application Number: 19165597.6 Filing Date: 2019-03-27 Inventor: Hunze, Stephan   Junge, Jens   Scherr, Maria Theresia   Assignee: Concept Laser GmbH   IPC: B22F3/105 Abstract: Apparatus (1) for additively manufacturing three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material which can be consolidated by means of an energy beam (2, 2'), which apparatus (1) comprises a determination device (6) adapted to determine at least one parameter of the energy beam (2, 2'), wherein the determination device (6) comprises at least one determination base body (11) arrangeable or arranged in a beam guiding plane (7), in particular a build plane, wherein at least one surface parameter of a surface (15) of the determination base body (11) is defined dependent on a surface parameter of a specific build material arrangeable or arranged in a build plane in an additive manufacturing process performed on the apparatus (1).
