Disclosed is a method for the removal of a part of a particle collecting device. The part is loaded with at least highly flammable particles and is removed from a process gas cleaning device of an additive manufacturing device by providing an inert gas which substantially encloses the particles, then removing the part of the particle collecting device from the process gas cleaning device, wherein the particles remain enclosed in the inert gas.

A de-dusting unit positionable in a vacuum chamber of a vacuuming device, where the vacuum chamber is delimited by a turbine, a first filter, and a second filter. The de-dusting unit includes a displacement module where the de-dusting unit is positionable within the vacuum chamber by the displacement module such that one of the first and second filters at a time is isolated from a suction flow and such that an oscillating movement of the de-dusting unit is transmitted to the isolated filter.
