Abstract
Apparatus (1) for additively manufacturing three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy beam (5), wherein a determination device (6) is provided that is adapted to determine at least one parameter relating to a focal position (7) of the energy beam (5) and/or a deviation from a nominal focal position, wherein the determination is based on an angular deviation of at least one part of the energy beam (5) relative to a nominal angle.

Apparatus (1) for additively manufacturing three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy beam (5), characterized by a determination device (6) adapted to determine at least one parameter relating to a focal position (7) of the energy beam (5) and/or a deviation from a nominal focal position, wherein the determination is based on an angular deviation of at least one part of the energy beam (5) relative to a nominal angle.
Method for operating at least one apparatus (1) for additively manufacturing three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy beam (5), characterized in that at least one parameter relating to a focal position (7) of the energy beam (5) and/or a deviation from a nominal focal position is determined via a determination device (6), wherein the determination is based on an angular deviation of at least one part of the energy beam (5) relative to a nominal angle.
