Manufacturing method and apparatus for producing three-dimensionally shaped object

To provide a Sintering method can reduce the inconvenience such as tool breakage trouble. A method for producing a powder layer and three-dimensionally shaped object is repeated formation of the solidified layer. For the surface of the solidified layer and / or solidified layer after three-dimensionally shaped object is obtained and / or three-dimensionally shaped object step of subjecting the surface cutting process the cutting device is included at least once. In particular, in this invention, the powder surrounding the solidified layer and / or three-dimensional shaped object with a suction nozzle prior to surface cutting processing was aspirated and the tip level B of the cutting device with the distal end level A of the suction nozzle when such suction is removed changing the relative positional relationship between the. .FIELD 7
