Abstract (en)
[origin: WO2018054727A1] The invention relates to a method for producing a workpiece by means of a powder bed-based additive production method. The workpiece (11) is produced in the powder bed (12) in that the powder bed is smoothed out to a target level (14) by means of a slide (13). If obstacles (17) (such as spatter for example) prevent the smoothing of the powder bed by means of the slide, the slide is deflected into a deflection position. According to the invention, the remaining powder (30) is removed by a tracked brush (23). The bristles are advantageously adapted precisely to the contour of the obstacle (17), whereby the removal of the remaining powder is achieved. The invention also relates to a system for the additive production of workpieces, wherein a slide and a brush are used simultaneously to smooth out the powder bed.
