Zusammenfassung:	The invention relates to a powder application device (10) for use in a system (100) for producing a three-dimensional workpiece by means of an additive layering method, the powder application device comprising a distribution element (12). The distribution element (12) is movable over a surface of a support (116) in order to apply a raw material powder onto the surface of the support (116) to produce a workpiece by means of an additive layering method. The powder application device (10) further comprises a powder carrier (16), which is movable over a support plane (E) and is provided with a surface profile (22) in the region of a surface (20) facing the support plane (E). The surface profile (20) comprises a carrying element (24a, 24b, 24c) and a through channel (26a, 26b, 26c). The carrying element (24a, 24b, 24c) and the through channel (26a, 26b, 26c) are shaped and arranged such that, when the powder carrier (16) is moved over the support plane (E) in a first movement direction (R1), pulverulent material d
