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.

Method for controlling operating of at least one additive manufacturing apparatus () for additively manufacturing of three-dimensional objects is provided by means of successive layerwise selective irradiation and consolidation of layers of a powdered build material which can be consolidated by means of an energy beam, embodiments including exemplary steps of: supplying authorization data (AD) which contains at least one authorization parameter that authorizes the operation of at least one additive manufacturing apparatus () or at least one functional unit (-) of the at least one additive manufacturing apparatus () from an external data supply source (), transmitting the authorization data (AD) from the external data supply source () to a control unit () of the at least one additive manufacturing apparatus (), and controlling operation of the additive manufacturing apparatus () or the at least one functional unit (-).

Method for controlling operation of at least one additive manufacturing apparatus for additively manufacturing of three-dimensional objects

A method for controlling the exposure of a selective laser sintering or laser melting apparatus. The method includes providing a selective laser sintering apparatus or laser melting apparatus that uses successive solidification of layers of a powder-type construction material that can be solidified using radiation. The apparatus comprises an irradiation device for irradiating layers of the construction material that has a plurality of scanners that can separately be actuated, simultaneously irradiating the construction material, the separate detection of irradiation times of each scanner and/or the irradiation areas detected by each scanner, and storing the detected irradiation times and/or irradiation areas; comparing the irradiation times and/or irradiation areas of the scanners with each other; re-determining the surface sections of a powder layer to be irradiated by each scanner so the irradiation times for each scanner are approximated to each other and/or the irradiation areas of each scanner are aligned.
