摘要： Apparatus (1) for additively manufacturing three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy beam (4), the apparatus comprising:
- at least one process chamber (7);
- a stream generating device (8) allocated to the at least one process chamber (7), the stream generating device (8) being adapted to generate at least one gas stream streaming through the process chamber (7) during operation of the apparatus (1);
- a connecting line (11) connecting the stream generating device (8) with the process chamber (7);
- the connecting line (11) being branched into at least two connecting line branches (11b1 - 11b3) at at least one branching point (BP), thereby, defining an unbranched section (11a) of the connecting line (11) and a branched section (11b) of the connecting line (11), wherein
- a first stream generating unit (12a) of the stream generating device (8) is allocated to the unbranched section (11a) of the connecting line (11), and
- at least one further stream generating unit (12b, 12c) of the stream generating device (8) is allocated to the branched section (11b) of the connecting line (11).-
