METHOD FOR PRODUCING A THREE-DIMENSIONAL OBJECT BY MEANS OF LASER SINTERING

摘要

The invention relates to a method for producing a three-dimensional object by means of laser sintering, the object being formed by compacting a powdery material layer by layer at the locations of the respective layers that correspond to the object by means of laser radiation, an IR-radiation image being captured in an applied powder layer, characterized in that on the basis of the IR-radiation image imperfections and/or geometric irregularities of the applied powder layer are determined.
