| description | The invention relates to a device (10) for producing a three-dimensional workpiece by carrying out an additive layering process, wherein the device (10) comprises:
- a build area (17) that is configured to receive a raw material powder layer;
- a powder application device (14) that is configured to deploy the raw material powder layer onto the build area (17);
- an irradiation system (20) that is configured to selectively irradiate the raw material powder layer on the build area (17);
wherein the device (10) is configured to provide at least one gas flow (48) that is directed along an axis (A) extending from a first edge region (44) of the build area (17) towards a second edge region (46) of the build area (17);
and wherein the device (10) comprises at least one gas flow guide element (36) that is configured to divert at least a part of the gas flow (48) away from the build area (17) before said gas flow (48) reaches the second edge region (46);
wherein the gas flow guide element (36) comprises a gas supply portion (56) that is configured to supply a fresh gas flow (54) along the build area (17). The invention also concerns a method for producing a three-dimensional workpiece. |
