Abstract
A method for the layered production of a component (10) from powdery material including loose powder particles, based on three-dimensional data of the component (10), including the method steps: the component (10) is segmented in a building direction (16) into N, N≥2 consecutive, cylindrical cross-sectional areas (11, 12, 13, 14, 15) 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 (16); the loose powder particles in the cross-sectional areas (11, 12, 13, 14, 15) of the component (10) 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 (16) are at least partially removed from the component (10) during the layered production of the component (10).
