METHOD AND DEVICE FOR IMPROVING THE COMPONENT QUALITY OF OBJECTS MANUFACTURED USING AN ADDITIVE MANUFACTURING METHOD

摘要

A method for providing control data for an additive manufacturing device has: a first step (S1) of accessing computer-based model data of at least one section of the object to be manufactured; a second step (S2) of generating at least one data model of a region of a build-up material layer to be selectively fused to manufacture the at least one object section, wherein the data model specifies the fusing of the build-up material by the movement of at least one beam along at least one fusion path (64, 65), wherein for the end point (64E, 65E) of the at least one fusion path (64, 65) a set of energy input parameter values is specified which acts as a reference value for the radiation power per unit area in the radiant action zone of the beam on the build-up material, said reference value being less than the reference value for the radiation power per unit area at other places on the fusion path (64, 65); and a third step (S3), in which control data corresponding to the at least one data model generated in the second step (S2) are provided for generating a control data set for the additive manufacturing device.
