Abstract
System (1) for additive manufacturing of three-dimensional objects (2), comprising: a movable modular functional unit (12a-12d), a tunnel structure (21), an apparatus (3) which is configured for additive manufacturing of a three-dimensional object (2) by successive layerwise selective exposure and consequent solidification by means of an energy beam (5) of construction material layers which have been formed, wherein the apparatus (3) comprises a connecting portion (26), by means of which the apparatus (3) can be or is connected to the tunnel structure (21) so that a modular functional unit (12a-12d) can be moved starting from the apparatus (3) into the tunnel structure (21) or vice versa, a filling and/or emptying device (13) which is configured for filling with construction material (4) a reception space of a functional unit (12a-12d) moved into a filling section (14) of the filling. and/or emptying device (13).
