Abstract (en)
[origin: WO2022018149A1] 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, 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 change a beam profile of the beam region during manufacture of a component by changing the control of the deflection unit (13).
