    Abstract: The invention relates to a device (1) for producing three-dimensional workpieces (15), comprising a carrier (7) for receiving raw material powder (9), a build chamber wall (11, 11a, 11b) which extend substantially vertically and which is adapted to laterally delimit and support the raw material powder (9) applied to the carrier (7); an irradiation unit (17) for selectively irradiating the raw material powder (9) applied to the carrier (7) with electromagnetic radiation or particle radiation in order to produce on the carrier (7) a workpiece (15) manufactured from the raw material powder (9) by an additive layer building method, wherein the irradiation unit (17) comprises at least one optical element; and a vertical movement device (31) which is adapted to move the irradiation unit (17) vertically relative to the carrier (7). The build chamber wall (11, 11a, 11b) and the carrier (7) are adapted to be connected to one another in a stationary manner during the vertical movement of the irradiation unit (17) so that the vertical movement takes place relative to the carrier (7) and relative to the build chamber wall (11, 11a, 11b).

    Abstract: We describe a method comprising: defining an irradiation section, in particular an irradiation stripe, on a material layer to be irradiated, in an additive layer manufacturing process, with an irradiation beam scanned across the material layer, and defining, within the irradiation section, two or more parallel or substantially parallel scanning vectors for said scanning of a said irradiation beam across the material layer, wherein all scanning vectors within the irradiation section are parallel or substantially parallel with respect to each other, wherein, based on said defining of the two or more parallel or substantially parallel scanning vectors, a line results which connects a first location, on the material layer, of a change in irradiation energy density of a said irradiation beam for a first one of the two or more parallel or substantially parallel scanning vectors and a second location, on the material layer, of a change in irradiation energy density of a said irradiation beam for a second one of the two or more parallel or substantially parallel scanning vectors, wherein the first scanning vector and the second scanning vector are neighboring scanning vectors, wherein a distance between the first location and the second location is smaller than (i) a distance between the first location and a third location of a change in irradiation energy density of a said irradiation beam for the second one of the two or more parallel or substantially parallel scanning vectors and/or (ii) a distance between the second location and a fourth location of a change in irradiation energy density of a said irradiation beam for the first one of the two or more parallel or substantially parallel scanning vectors, and wherein an angle, which differs from 90 degrees (a) irrespectively of a geometry of a workpiece to be produced using the additive layer manufacturing process, and (b) irrespectively of an orientation of the two or more parallel or substantially parallel scanning vectors with respect to an orientation of the irradiation section, is formed (i) between the first scanning vector and the line, and/or (ii) between the second scanning vector and the line.
