Abstract

Method for calibrating an apparatus for manufacturing a three-dimensional object by layer-wise selective solidification of building material with the step of generating an substantially periodic first modulation pattern in a first sub-area of the build area, the step of generating an substantially periodic second modulation pattern in a second sub-area of the build area, wherein in the overlap zone, the first modulation pattern and the second modulation pattern form an substantially periodic superposition pattern, whose period is larger than the period of the first modulation pattern and the period of the second modulation pattern, the step of detecting the superposition pattern, and the step of determining the deviation of the position of the superposition pattern on the build area from a reference position.
