Abstract (en)
[origin: WO2022018148A1] The invention relates to a manufacturing device (1) for additive manufacturing of components from a powder material, comprising a beam generation device (3) designed to generate an energy beam (5), a scanner unit (7) designed to move the energy beam (5) within a working area (9) to a plurality of irradiation positions (11) to produce, by means of the energy beam (5), a component from the powder material in the working area (9), a deflection unit (13) designed to move the energy beam (5) in an irradiation position (11) of the plurality of irradiation positions (11) within a beam region (15) to a plurality of beam positions (17), and a control unit (19), which is operatively connected to the deflection unit (13) and is designed to control the deflection unit (13) and to produce a specific beam profile in the beam region (15) by specifying at least on operation parameter of the deflection unit (13), the at least one operating parameter being selected from the group consisting of: a dwell time in a beam position (17), a beam position density distribution in the beam region (15), a frequency distribution of the beam positions (17), and an intensity-influencing parameter for influencing the relevant intensity of the energy beam (5) deflected to the beam positions (17).
