  • Patent number: 10682700
    Abstract: A device is disclosed for producing a three-dimensional object by layerwise construction. The device contains a flow device for generating a gas flow above an applied layer of the building material by means of a nozzle element for introducing the gas into the device. The nozzle element includes a body with a gas inlet side and a gas outlet side, and channels which penetrate the body from the gas inlet side to the gas outlet side, provided with inlet openings on the gas inlet side and gas outlet openings on the gas outlet side, and which are separated by walls. The length of the channels is selected such that a laminar flow is formed at the gas outlet side.

  • Publication number: 20170216916
    Abstract: A device (1), for producing a three-dimensional object (2) by solidifying, layer-by-layer, building material (13) at locations in the respective layer corresponding to the cross-section of the object (2) to be produced, contains a flow device (31, 32, 34, 35) for generating a gas flow above an applied layer of the building material (13) by means of a nozzle element (40) for introducing the gas into the device. The nozzle element (40) comprises a body (41) with a gas inlet side and a gas outlet side (46), and a plurality of channels (42) which penetrate the body from the gas inlet side (44) to the gas outlet side (46), are provided with inlet openings on the gas inlet side (44) and with gas outlet openings (47) on the gas outlet side (46), and which are separated by walls (43). The length of the channels (42) is selected such that therein a laminar flow is formed at the gas outlet side (46).
