Original Abstract Submitted

disclosed is a method of oxidizing welding fume residues of an additive manufacturing apparatus adapted to process a metal-based building material. the additive manufacturing apparatus includes a process chamber for manufacturing a three-dimensional object and a circulation system having a gas circuit for a protective gas which is passed through the process chamber. the welding fume residues are exposed for a passivation time period to a gas atmosphere containing an oxidizing agent in a chamber, where the passivation time period is ended depending on a difference between oxidizing agent concentrations in the chamber detected by at least one sensor at two points in time having a predetermined distance from one another.
