Zusammenfassung:	The present invention relates to a doctor blade unit for an additive manufacturing system having a pulverous starting material. By means of the doctor blade unit according to the invention, improved linearity of the doctor blade and parallelism with respect to the build plane are achieved. The doctor blade is suspended on a crossmember by means of adjustable fastening elements, and the crossmember in turn is fastened, on one side by means of a fixed bearing and on the other side by means of a floating bearing, to a guide support.
