DETERMINATION DEVICE FOR DETERMINING A SCAN VELOCITY OF AN ENERGY BEAM
Publication/Patent Number: US2020061924A1 Publication Date: 2020-02-27 Application Number: 16/290,959 Filing Date: 2019-03-04 Inventor: Burggraf, Udo   Assignee: CONCEPT LASER GMBH   IPC: B29C64/393 Abstract: Determination device (9) for determining a scan velocity of an energy beam (5) for an 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 (5), wherein the determination device (9) comprises a determination unit (10) that is arrangeable or arranged in a process chamber (7) of an apparatus (1) for additively manufacturing three-dimensional objects, wherein the determination device (9) is adapted to determine a scan velocity with which the energy beam (5) is guided along a closed scan path (14, 14′) based on the scan time required for guiding the energy beam (5) along the closed scan path (14, 14′).
