    摘要: The present invention relates to powder recoating systems or recoaters for additive manufacturing applications. A powder recoating system comprises a recoating an endless chain conveyor (2) and a recoating arm (1) attached thereto. The endless chain conveyor (2) is arranged so that the recoating arm (1) is able to move a powder (P) from the powder delivery assembly (3) to the fabrication powder bed (4) recoating thereof. The endless chain conveyor (2) having lower run (21) and upper run (22) arranged so that the recoating arm (1) moving along the lower run (21) conveys the powder (P) from the powder delivery assembly (3) to the fabrication powder bed (4) recoating thereof and moving along the upper run (22) repositions for the next transfer of the powder (P) from the powder delivery assembly (3) to the fabrication powder bed (4).

    摘要: An additive manufacturing apparatus serves for producing a three-dimensional object (2) by means of successively solidifying layers of a building material (13) within a build area (10) of the additive manufacturing apparatus (1), the layers corresponding to cross-sections of the object (2) to be produced. The additive manufacturing apparatus (1) comprises a process chamber (3) for building the object (2), the process chamber (3) comprising the build area (10) and a ceiling (4a) of the process chamber located opposite the build area (10), and a nozzle element (43) for introducing a gas into the process chamber (3), the nozzle element (43) being arranged in the ceiling (4a) of the process chamber (3). The nozzle element (43) comprises an inlet (61), an outlet (62), and a plurality of gas flow passages (65, 65a, 65b) being in fluidic communication with the inlet (61) and the outlet (62) for receiving a gas at the inlet (61) and supplying the gas through the outlet (62) into the process chamber (3), wherein the outlet (62) faces the build area (10), preferably at least a center region of the build area (10), and the outlet (62) of the nozzle element (43) has a substantially elongate shape, the elongate shape defining a longitudinal direction (l) of the nozzle element (43), and wherein the plurality of gas flow passages (65, 65a, 65b) subdivide a cavity of the nozzle element (65) at least along the longitudinal direction (l).
