1. An apparatus for additively manufacturing three-dimensional objects, the apparatus comprising:
a housing structure;
a first irradiation device comprising a first irradiation element configured to generate a first energy beam directable to a construction plane defined by a build material layer to selectively irradiate the build material layer;
a first magnetic mounting and displacement device, the first magnetic mounting and displacement device comprising:
a first magnetic stator element arranged or formed on the housing structure, and
a first magnetic slider element arranged or formed on the first irradiation element, the first irradiation element being displaceably supported by the first magnetic mounting and displacement device;
a second irradiation device comprising a second irradiation element configured to generate a second energy beam directable to the construction plane defined by the build material layer to selectively irradiate the build material layer; and
a second magnetic mounting and displacement device, the second magnetic mounting and displacement device comprising:
a second magnetic stator element arranged or formed on the housing structure, and
a second magnetic slider element arranged or formed on the second irradiation element, the second irradiation element being displaceably supported by the second magnetic mounting and displacement device;
wherein the first magnetic stator element comprises a first planar stator element portion defining a first movement path and/or a first movement plane for displaceably supporting the first irradiation element, wherein the first planar stator element is positioned at an elevation above the construction plane and oriented in a parallel position relative to the construction plane; and
wherein the second magnetic stator element comprises a second planar stator element portion defining a second movement path and/or a second movement plane for displaceably supporting the second irradiation element, wherein the second planar stator element positioned at an elevation above the construction plane and oriented in an angular position relative to the construction plane.
