Abstract
Apparatus () for additively manufacturing of three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material which can be consolidated by means of an energy beam, with a stream generating unit () configured to generate a stream of a process gas () being capable of being charged with particles (), in particular non-consolidated particulate build material and/or smoke and/or smoke residues, generated during operation of the apparatus () and a filter unit () configured to separate particles () from the stream of process gas (), wherein the filter unit () comprises a filter chamber () with at least one filter element () at least partly arranged in the streaming path of the generated stream of process gas (), wherein particles () in the stream of process gas () are separated from the process gas () by the filter element (), wherein a particle reception chamber () is separably connected or connectable to a particle outlet () of the filter chamber () and configured to receive the particles () separated from the process gas ().
