Three-dimensional laminating and fabricating system, three-dimensional laminating and fabricating method, laminating and fabricating control apparatus and method of controlling the same, and control program

A method of three-dimensional laminating and fabricating, comprising:

• fabricating each layer of a laminated and fabricated object, the each layer comprising an aggregate of cell regions, using a laminating and fabricating unit that includes a squeegeeing blade configured to spread a laminating material on an upper layer of the laminated and fabricated object, and an irradiator configured to irradiate the laminating material;
• and
• controlling the laminating and fabricating unit such that a scanning direction in which the irradiator irradiates the laminating material while scanning in each of the cell regions changes with respect to a moving direction represented by a vector of the squeegeeing blade during laminating and fabricating, wherein the scanning direction is selected from directions having acute angles with respect to the moving direction of said squeegeeing blade,
• wherein, in the controlling the laminating and fabricating unit, laminating and fabricating conditions and a history of changes in the scanning direction are accumulated in association with each other, and the changes in the scanning direction during laminating and fabricating are selected based on the laminating and fabricating conditions, wherein the laminating and fabricating conditions include the laminating material, characteristics of the laminating and fabricating unit and features of data of the laminated and fabricated object.

A laminating and fabricating control apparatus comprising:

• a data acquirer that acquires data of a laminated and fabricated object as a target of laminating and fabricating;
• and
• a scanning direction controller configured to control, based on the data of the laminated and fabricated object, a laminating and fabricating unit fabricating each layer of the laminated and fabricated object, the each layer comprising an aggregate of cell regions, such that a scanning direction in which a laminating material while scanning in each of the cell regions is irradiated changes, during laminating and fabricating, with respect to a moving direction represented by a vector of a squeegeeing blade configured to spread the laminating material on an upper layer of the laminated and fabricated object, wherein the scanning direction is selected from directions having acute angles with respect to the moving direction of said squeegeeing blade,
• wherein said scanning direction controller comprises an accumulator that accumulates laminating and fabricating conditions and a history of changes in the scanning direction in association with each other, and a selector that selects the changes in the scanning direction during the laminating and fabricating based on the laminating and fabricating conditions, wherein the laminating and fabricating conditions include the laminating material, characteristics of the laminating and fabricating unit and features of the data of the laminated and fabricated object.

A method of controlling a laminating and fabricating control apparatus, comprising:
