Apparatus () for additively manufacturing three-dimensional objects () by means of successive layerwise selective irradiation and consolidation of layers () of a build material () which can be consolidated by means of an energy source.

Apparatus for additively manufacturing 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.
