    摘要： An apparatus for carrying out a method for producing an object using selective powder melting and by building up layers of powder material. The apparatus includes a build chamber configured to accommodate the object being produced and a powder delivery device equipped with a powder storage container and configured to supply material powder into the build chamber, a powder layer preparation unit to prepare successive layers of the supplied material powder on a substrate arranged in the build chamber, an irradiation device configured to irradiate a prepared powder layer to thereby melt the prepared powder layer locally, and a protective gas circulation device configured to circulate a protective gas present in the build chamber. At least one air conditioning device is also included and is configured to condition one or more of a temperature or a humidity of the protective gas circulated by the protective gas circulation device.
