摘要

The invention relates to a powder applicator unit (8) for a PBLS system (1), wherein the powder applicator unit (8) comprises an application medium, which is mounted movably parallel to a working plane of the PBLS system (1) in order to move powder along the working plane can, wherein a distance of the application medium to the working plane is variable. In order to provide an improved powder application unit, it is provided that the application medium is pivotably mounted about a pivot axis (S) in order to pivot the application medium away from the working plane. Moreover, the invention relates to a method for applying two successive powder layers in a PBLS process.
