Abstract

Build material handling unit (2) for a powder module (3) for an apparatus for additively manufacturing three-dimensional objects, which apparatus is adapted to successively layerwise selectively irradiate and consolidate layers of a build material (4) which can be consolidated by means of an energy source, wherein the build material handling unit (2) is coupled or can be coupled with a powder module (3), wherein the build material handling unit (2) is adapted to level and/or compact a volume of build material (4) arranged inside a powder chamber (5) of the powder module (3) by controlling the gas pressure inside the powder chamber (5).
