Document Type and Number:
Japanese Patent JP2019085641
Kind Code:
A
Abstract:
To provide an apparatus for additively manufacturing three-dimensional objects, increasing the efficiency of removal of fume particles or smoke particles from the process chamber.SOLUTION: An apparatus comprises: a stream generating device (8) for generating at least one gas stream streaming through a process chamber (7) during operation of the apparatus (1); and 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, 11b2) 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 (12a, 12b) of the stream generating device (8) is allocated to the branched section (11b) of the connecting line (11).SELECTED DRAWING: Figure 1
