| description | Apparatus (1) for additively manufacturing three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a powdered build material (3) which can be consolidated by means of an energy beam (4), the apparatus (1) comprising a process chamber (8) and a stream generating device (9) configured to generate a gaseous fluid stream at least partly streaming through the process chamber (8), the gaseous fluid stream being capable of being charged with non-consolidated particulate build material, particularly smoke or smoke residues generated during operation of the apparatus (1), while streaming through the process chamber (8), wherein the stream generating (9) device comprises at least two separate stream generating units (13, 14) each being configured to generate a respective gaseous fluid stream. |
