Abstract
A method for the layered production of a component () from powdery material including loose powder particles, based on three-dimensional data of the component (), including the method steps: the component () is segmented in a building direction () into N, N≥2 consecutive, cylindrical cross-sectional areas () made up of a two-dimensional cross-sectional surface and a layer thickness; N powder layers of the powdery material are applied to a building plane perpendicular to the building direction (); the loose powder particles in the cross-sectional areas () of the component () are at least partially bonded to each other and to the underlying cross-sectional area and; loose powder particles arranged within one cross-sectional area or within multiple consecutive cross-sectional areas in the building direction () are at least partially removed from the component () during the layered production of the component ().
