Abstract: A method of additively manufacturing a three-dimensional object may include allocating irradiation of respective ones of a plurality of sequential layers of construction material between a first region and a second region based at least in part on a first irradiation time and/or a second irradiation time. Irradiation of the first region is allocated to a first scanner and the first irradiation time is indicative of a time required for the first scanner to irradiate the first region with respect to at least one of the plurality of sequential layers of construction material. Irradiation of the second region is allocated to a second scanner and the second irradiation time is indicative of a time required for the second scanner to irradiate the second region with respect to at least one of the plurality of sequential layers of construction material. The first irradiation time and the second irradiation time may be at least approximately the same.
