Abstract
A method and apparatus for the generative manufacture of a three-dimensional component in a processing chamber, in which the steps 'providing a metallic starting material in the processing chamber' and 'melting the starting material by means of energy input' are repeated multiple times, wherein a process gas is provided in the processing chamber are disclosed. The method is characterized by the steps: 1) the hydrogen content of the process gas or a sample of the process gas is determined; 2) the oxygen content of the process gas or a sample of the process gas is determined by means of an oxygen sensor and/or the dew point of the process gas or a sample of the process gas is determined; and 3) the values for the oxygen content and/or the dew point determined in step 2 are corrected by means of the value for the hydrogen content determined in step 1.
