Method for operating an apparatus for additively manufacturing of three-dimensional objects

Method for operating at least one apparatus (5, 6) for additively manufacturing of three-dimensional objects (7-9) by means of successive layerwise selective irradiation and consolidation of layers of a build material (10) which can be consolidated by means of an energy beam (11), characterized in that a communication interface (4) connected or connectable with the at least one apparatus (5, 6) is adapted to receive at least a first data set (14, 15) comprising object data from at least a first user (1, 2) of a first user group (3), relating to at least one object (7-9) to be built, and at least a second data set (16, 17) from at least one second user (18, 19) of a second user group (20), wherein the at least one first data set (14, 15) and/or the at least one second data set (16, 17) is stored and/or build data are generated and/or stored relating to the at least one object (7-9) to be built corresponding to the received data sets (14-17).
