Abstract: An apparatus (10) for producing three-dimensional work pieces comprises a process chamber (12) accommodating a carrier (16) and a powder application device (14) for applying a raw material powder onto the carrier (16) and being provided with a gas inlet (30) and a gas outlet (32). The apparatus (10) further comprises an irradiation device (18) for selectively irradiating electromagnetic or particle radiation onto the raw material powder applied onto the carrier (16) in order to produce a work piece made of said raw material powder by an additive layer construction method. A gas circuit (34) of the apparatus (10) comprises a circulation line (36) connecting the gas outlet (32) of the process chamber (12) to the gas inlet (30) of the process chamber (12) and a filter system (40) arranged in the circulation line (36). Furthermore, a cyclone separator system (42) is arranged in the circulation line (36) upstream of the filter system (40).

Abstract: A method for controlling an irradiation system (20) for use in an apparatus (10) for producing a three-dimensional work piece and comprising a plurality of irradiation units (22a, 22b) a first and a second irradiation area (18a, 18b) as well as an overlap area (26) arranged between the first and the second irradiation area (18a, 18b) is defined on a surface of a carrier (16) adapted to receive a layer of raw material powder. A first irradiation area (22a) of the irradiation system (20) is assigned to the first irradiation area (18a) and the overlap area (26), and a second irradiation unit (22b) of the irradiation system (20) is assigned to the second irradiation area (18b) and the overlap area (26). If it is determined that a section (S) or a radiation pattern according to which radiation beams (24a, 24b) emitted by the irradiation units (22a, 22b) of the irradiation system (20) are guided over the layer of raw material powder received on the carrier (16) and/or a contour (C) of the three-dimensional work piece to be produced extend(s) into the first and the second irradiation area (18a, 18b) defined on the surface of the carrier (16), said section (S) of the radiation pattern and/or said contour (C), in a splitting region of the section (S) of the radiation pattern and/or the contour (C) which is located in the overlap area (26) arranged between the first and the second irradiation area (18a, 18b), is split into a first portion (S1, C1) and a second portion (S2, C2). The first portion (S1, C1) of said section (S) of the radiation pattern and/or said contour (C) is assigned to the first irradiation unit (22a) and the second portion (S2, C2) of said section (S) of the radiation pattern and/or said contour (C) is assigned to the second irradiation unit (22b).
