Abstract

An apparatus for additively manufacturing three-dimensional objects may include a first detection device configured to detect a first process parameter during operation of the apparatus, and to generate a first data set comprising information relating to the first process parameter, a second detection device configured to detect a second process parameter during operation of the apparatus, and to generate a second data set comprising information relating to the second process parameter; and a data processing device configured to determine a mutual dependency between the first process parameter and the second process parameter based at least in part on the first data set and the second data set. The mutual dependency may include a possible influence or a real influence of the first process parameter on the second process parameter. The first process parameter may include a chemical parameter and/or a physical parameter of an atmosphere within a process chamber of the apparatus. The second process parameter may include a chemical parameter, a geometrical parameter, and/or a physical parameter of build material during operation of the apparatus.
