Method for operating at least one apparatus (1) for additively manufacturing of three-dimensional objects (2-4) by means of successive layerwise selective irradiation and consolidation of layers of a build material (5) which can be consolidated by means of an energy beam (6), wherein a communication interface (10) connected or connectable with the at least one apparatus (1) is adapted to receive at least a first data set (15-17) comprising object data from at least a first user (12-14), relating to at least one object (2-4) to be built, and at least a second data set (15-17) comprising object data from at least a second user (12-14), wherein a manufacturing process of at least two objects (2-4) is controlled dependent on the data sets (15-17) of the at least two users (12-14).

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), wherein 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).
