Abstract (en)

[origin: WO2022135817A1] The invention relates to a method for powder-bed-based additive manufacturing of a component (10), comprising setting irradiation vectors (Vh, Vc) for a layer (L) to be irradiated for the component (10), wherein: irradiation vectors (Vh, Vc) are irradiated below a length of 1 mm in a pulsed irradiation operation (pw); and a pulse frequency below 3 kHz and a scan speed below 250 mm/a are selected. The invention also relates to a correspondingly manufactured component, to an associated method for providing manufacturing instructions, and to an associated computer program product.
