Document Type and Number:
Japanese Patent JP2019022976
Kind Code:
A
Abstract:
To provide an apparatus for additively manufacturing of three-dimensional objects with improved calibration of energy beams.SOLUTION: An apparatus (1) for additively manufacturing of 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 (4, 5), wherein the apparatus (1) comprises a scanning unit (6) configured to scan the energy beam (4, 5) over at least a part of a build plane (7), a focusing unit (15) is provided that is configured to control a focal position (13, 14) of the energy beam (4, 5) via a positioning of at least one optical component of the focusing unit (15) and/or a positioning of the focusing unit (15) relative to the build plane (7).SELECTED DRAWING: Figure 1
