A laminate molding equipment (1) includes a molding part (2) provided with a molding table (23) on which a three-dimensional shape molded object is molded, a powder layer forming part (3) configured to supply material powder on the molding table (23) to form a powder layer (M), a light beam radiating part (4) configured to radiate a light beam to the powder layer (M) laminated on the molding table (23) and select a region to form a solidified layer, and a control part (5) configured to control operation of the respective parts, wherein the control part (5) recognizes a moldable region on the powder layer (M) already formed while the powder layer forming part (3) starts forming one powder layer and completes forming the one powder layer, and radiates the light beam in the moldable region. As a result, molding time can be shortened by starting the light beam radiation without waiting for completion of the formation of the powder layer.
摘要:
In a metal powder processing equipment where metal powder (7) is sequentially laminated on a table (2) of a chamber (1) and laser beam melting or electron beam melting is performed, or cutting and shaping are performed by a rotating tool subsequently to melting, a first temperature adjusting unit is placed at a lower bottom portion of the table (2) and a second temperature adjusting unit is disposed in a state of contact with said outer wall around the entire outer wall of the chamber (1), and both units are simultaneously heated or cooled. Further, a room (6) partially enclosing a metal powder reserve tank (4) and a metal powder supply pipe (5) is provided with a third temperature adjusting unit (60), and a temperature of the third temperature adjusting unit (60) is set to an average temperature of the second temperature adjusting unit (10) before the second one is actuated. Consequently, a deterioration of dimensional precision in processing and a deterioration of metal powder quality can be prevented by keeping the heating temperature constant.
