Patent ID: 11472110

Abstract:
The invention relates to a facility (1) for the manufacture of three-dimensional objects from material powder, through layerwise consolidation of said material powder present on a process surface (42) in such places of the particular layer (40) that correspond, in accordance with geometrical data, to the object about to be manufactured, wherein the facility (1) comprises a process floor (46) surrounding the process surface and a powder feed device (10) to feed, provide and distribute the powder on the process surface (42), wherein the powder feed device (10) comprises: a conveying element (12) for feeding powder into the powder feed device (10), a reservoir (14), into which the at least one conveying element (12) feeds the powder, a process conveying element (16), which can act on powder in the reservoir (14), in order to provide this in dosed quantity on the process floor (46) adjacent to the process surface (42), a process pusher (18) for distributing the powder provided adjacent to the process surface (42) over the process surface (42), wherein the process conveying element (16) is designed, such that the powder adjacent to the process surface (42) can be provided in the form of a line.
