Abstract (en)
[origin: WO2022043164A1] The invention relates to a manufacturing device (1) for additively manufacturing components (3) from a powder material, comprising - a beam generation device (5) for generating a plurality of energy beams (7), - a scanner device (9) for at least intermittently irradiating a work region (11) in locally selective fashion by means of the energy beams (7), - an inert gas device (15) for generating an inert gas flow with a defined inert gas flow direction (P1), and comprising - a control device (17) configured to control the scanner device (9), wherein - the control device (17) is further configured to: define a first irradiated area (19.1) on the work region (11) for a first energy beam (7.1), a first irradiated portion (21.1) for the first energy beam (7.1) being displaced along said irradiated area from a first start position to a first end position within the first irradiated area (19.1); - define upstream of the first irradiated area (19.1) a second irradiated area (19.2) for a second energy beam (7.2), a second irradiated portion (21.2) for the second energy beam (7.2) being displaced along said second irradiated area from a second start position to a second end position, and to: - start an irradiation of the second irradiated area (19.2) with the second energy beam (7.2) once the first irradiated portion (21.1) and the second start position are not arranged relative to one another within an interaction zone determined by the inert gas flow direction.
