Abstract
A lamination molding apparatus which can lower the oxygen concentration in a molding room in short time is provided. A lamination molding apparatus, including a molding room; a processing head; a driving device housing room housing a driving device moving the processing head; a partitioning section to partition the molding room from the driving device housing room; a discharging section to discharge gas in the molding room; and an inert gas supplying apparatus to supply the inert gas to both of the molding room and to the driving device housing room.
Claims8
A lamination molding apparatus, comprising:
- a molding room covering a predetermined molding region and filled with an inert gas having a predetermined concentration;
- a laser beam emitter to irradiate a predetermined portion of a material powder layer formed on the molding region with a laser beam, thereby sintering the material powder at a position of irradiation to form a sintered body;
- a processing head structured to be capable of being moved in the molding room, the processing head providing a machine processing to the sintered body;
- a driving device housing room provided adjacent to the molding room, the driving device housing room housing a driving device moving the processing head;
- a partitioning section to partition the molding room from the driving device housing room;
- a discharging section to discharge gas in the molding room;
- and
- an inert gas supplying apparatus to supply the inert, gas to both of the molding room and to the driving device housing room;
- wherein a communicating section is in the partitioning section, the communicating section allowing communication between, the driving device housing room and the molding room;
- and
- the communicating section has a size allowing to maintain a pressure of the driving device housing room supplied with the inert gas to be higher than a pressure of the molding room.
