Abstract
A method for operating a metal printing device has an enclosure in which the metal printing is carried out, the enclosure having an inlet and an outlet, and a fan also being provided, with which the atmosphere in the enclosure can be regenerated, a device also being provided in order to be able to extract particles in particular after a printing process is complete. In a first method step, process gas is extracted from the enclosure and conducted through a regeneration device in order to clean the atmosphere in the enclosure. In a second method step after the printing process is complete, excess particles are removed from the enclosure. A suction fan having a suction line connection is provided, wherein the mode can be switched over using a switchover device connected upstream of the suction fan.
