Zusammenfassung:The disclosure provides methods of additive manufacture of components in layers in a powder bed by at least two laser beams that can be deflected two-dimensionally over the same powder bed region. Each laser focal spot is projected onto the power bed and is or is set to a diameter of less than or equal to 300 μm. Components to be produced in the powder bed region are manufactured by each of the laser beams, and each individual surface contour of the component is manufactured solely by one of the laser beams.
