摘要： The present invention has: a setting step for setting lamination patterns respectively for an outer edge portion and an inner portion of a shape indicated by shaping data; and an adjustment step for adjusting a forming sequence such that, during manufacturing when the lamination patterns are used to laminate and thereby form the outer edge portion and the inner portion, the height of the already laminated outer edge portion is higher than the height of the inner portion that is being newly laminated. In the lamination patterns, the orientation of the heat source when a region positioned at a boundary with the outer edge portion is formed is set so as to be inclined at a prescribed angle toward the outer edge portion in a plan perpendicular to a movement direction of the heat source.

摘要： A suction apparatus is provided with: a first path connecting an inlet and a drive opening of an ejector; a second path connecting a suction/ejection opening and an intake opening of the ejector; and a third path connecting the inlet and the suction/ejection opening. When the second path is connected by a path switching unit, a gas or an aerosol is suctioned via the suction/ejection opening by means of the first path and the second path. When the third path is connected by the path switching unit, a compressed gas is ejected via the suction/ejection opening by means of the third path.
