Abstract

An apparatus (1) for additive manufacturing of three-dimensional objects (2) by successive, selective layer-by-layer exposure and thus solidification of construction material layers of a construction material (3) that can be solidified by means of a laser beam (5) generated by a laser beam generation device (4), comprising:—a laser beam generation device (4) provided for generating a laser beam (5) with beam properties defined by at least one laser beam parameter, especially a beam profile defined by at least one laser beam parameter;—a modulation device (9) assigned to the laser beam generation device (4) provided for purposefully changing at least one laser beam parameter that influences the beam properties, especially the beam profile, of the laser beam (5) generated by the laser beam generation device (4) on the basis of a target value that is or can be specified, especially by a user.
