Abstract
Apparatus () 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 () adapted to filter residues from at least one stream of process gas (), characterized by at least one positioning device () adapted to at least partly automatically transfer the filter unit () or at least a part of the filter unit between a disconnected state in which the filter unit () is disconnected from the stream of process gas () to a connected state in which the filter unit () is connected to the stream of process gas ().
