The utility model discloses a cabin arrangement structure that quick deoxygenation that is used for laser selective melting to make, through adjustment, planning sealing cabin specific structures, it is slow to have solved cabin deoxygenation speed, the not thorough problem of deoxygenation. The inert gas introducing port is add at the carminative dead angle of deoxidization that is hard to in cabin to its technical scheme main points, realizes some incentive measures, keeps apart do not being equipped with transition export and gas outlet with transition space punishment, is equipped with the cowling panel between transition export and the gas outlet, and the cabin is separated into in the ventilation route of the planning and designing of mutual intercommunication to the cowling panel, and the inert gas who gets into in the cavity from the transition export flows along the ventilation route of planning and designing, arranges the indoor gas of egress simultaneously. It is fast to have reached the deoxygenat
