Abstract
The present invention relates to a method for the production of a three-dimensional object () by way of layered solidification of a powder construction material () by way of electromagnetic radiation, in particular laser radiation, having the steps: scanning points, which correspond to a cross section of the object () to be produced, of an applied layer of the powder construction material () with an electromagnetic beam () from a radiation source () for purposes of selectively solidifying the powder construction material (), conducting a gas flow () across the applied layer during the scanning with the electromagnetic beam () and performing an irregularity determination with regard to the presence of a process irregularity with regard to at least one process parameter during the production, wherein during the scanning by way of the electromagnetic beam (), the scanning process at least one present point of the cross section to be solidified is interrupted on the basis of a result of the irregularity determination.
