Abstract

Apparatus (1, 23, 27, 30) for additively manufacturing of 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, whereby the apparatus (1, 23, 27, 30) comprises at least one process chamber (4) with at least one chamber separation device (5, 24, 28, 31) separating a process region (6) into a first sub-region (7) and a second sub-region (8) of the process chamber (4), wherein the chamber separation device (5, 24, 28, 31) comprises at least one separation element (9, 29, 31) that is moveable and/or deformable, wherein the separation element (9, 29, 31) is configured to create a passageway (18) between the first and the second sub-region (7, 8) for at least one tool carrier (19).
