Abstract
A method and apparatus for the generative production of a three-dimensional component in a processing chamber are disclosed. The method performs the steps of providing a metal starting material in the processing chamber and melting the starting material by inputting energy, which are repeated multiple times. A process gas is passed through the processing chamber in a circuit. Hydrogen is added to the circulating gas, then the circulating gas is heated to a temperature above 500 ° C. and then cooled to a temperature below 60 ° C.
