Abstract: Plant (1) for additively manufacturing at least one three-dimensional object (2), comprising at least one process station (3a-3c) being configured to perform an additive manufacturing process and/or at least one preprocessing process for an additive manufacturing process and/or at least one postprocessing process for an additive manufacturing process; at least one conveying device (19) configured to convey an item (20) between at least two positions (P1, P2) of the plant (1), the conveying device (19) comprising at least one conveying element (22), the at least one conveying element (22) being at least partially bound to ground (23), and at least one conveying carriage (24) being connectable or connected with the conveying element (22) so as to be moveable between at least two positions (P1, P2) of the plant (1), the at least one conveying carriage (24) comprising at least one supporting interface (25) for supporting at least one item (20).

Abstract: Apparatus (17, 24) 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 source, with a filter unit (4) adapted to filter residues from at least one stream of process gas (18), characterized by at least one positioning device (1, 25, 28) adapted to at least partly automatically transfer the filter unit (4) or at least a part of the filter unit between a disconnected state in which the filter unit (4) is disconnected from the stream of process gas (18) to a connected state in which the filter unit (4) is connected to the stream of process gas (18).
