  • Publication number: 20180215102
    Abstract: This invention provides a laminating and fabricating control apparatus for correcting a laser irradiation position in correspondence with a shift of the laser irradiation position during laminating and fabricating by an optical fabricating unit. The laminating and fabricating control apparatus controls a laminating and fabricating unit that includes a squeezing blade configured to spread a laminating material on an upper layer of a laminated and fabricated object, and an irradiator configured to irradiate the laminating material, to fabricate the laminated and fabricated object. The laminating and fabricating control apparatus includes a position shift acquirer that acquires a shift of an irradiation position of irradiation light on a surface of the squeezing blade when receiving the irradiation light from the irradiator, and an irradiation position corrector that corrects the irradiation position by the irradiator based on the shift of the irradiation position.

  • Patent number: 9623512
    Abstract: In metal powder processing equipment where metal powder is sequentially laminated on a table of a chamber and laser beam melting or electron beam melting is performed or cutting and shaping are performed by a rotating tool subsequent to melting, a first temperature adjusting unit is placed at a lower bottom portion of the table and a second temperature adjusting unit is disposed in contact with and around the outer wall of the chamber and both units are simultaneously heated or cooled; a room partially enclosing a metal powder reserve tank and a metal powder supply pipe is provided with a third temperature adjusting unit, the temperature of which is set to average temperature of the second temperature adjusting unit before the second one actuates, so that deterioration of dimensional precision in processing and deterioration of metal powder quality can be prevented by keeping heating temperature constant.
