Method and device for the layered additive manufacturing of components by means of a continuous and a pulsed laser beam and associated computer program product

摘要

In a method, in particular LMF or SLS method, for layer-wise additive manufacturing of components (2) in a powder bed (5) by means of at least two over the same powder bed area (12) two-dimensionally deflectable, different laser beams (3a, 3b), said areas (7) of a component (2) to be produced, which have increased requirements for surface roughness or dimensional accuracy, exclusively with the one laser beam (3a) and regions (8) of the component (2) to be produced, which have no increased requirements for surface roughness or dimensional accuracy With the other laser beam (3b) are melted, according to the invention, one laser beam, a pulsed laser beam (3a) and the other laser beam, a continuous laser beam (3b).
