Method and apparatus for treating combustible and/or reactive particles, method of operating a system for producing a three-dimensional work piece and system for producing a three-dimensional work piece
In a method for treating combustible and/or reactive particles (34) which have been separated from a gas stream (32) by means of a separation device (36) an oxidizing agent is supplied to an atmosphere surrounding the particles (34) so as to cause a passivating oxidation of at least a part of the particles (34). A content of the oxidizing agent in the atmosphere surrounding the particles (34) is detected and the supply of the oxidizing agent to the atmosphere surrounding the particles (34) is controlled in dependence on the detected content of the oxidizing agent in the atmosphere surrounding the particles (34).

The irradiation unit comprises a radiation source configured to generate the radiation beam, a first scanning unit configured to receive the radiation beam and to scan the radiation beam over a first irradiation area of the uppermost layer of the raw material, a second scanning unit configured to receive the radiation beam and to scan the radiation beam over a second irradiation area of the uppermost layer of the raw material, and a switching unit configured to direct the radiation beam generated by the radiation source to the first scanning unit or the second scanning unit. The apparatus further comprises a control unit configured to perform control of the switching unit to switch from a first switching state, in which the radiation beam is directed to the first scanning unit and not to the second scanning unit, to a second switching state, in which the radiation beam is directed to the second scanning unit and not to the first scanning unit.
