Abstract: This additive manufacturing method includes a step for dividing a three-dimensional model form into a plurality of layers, and dividing each of the divided layers into a plurality of bead models. A trapezoidal bead model has four vertices. In the step of dividing the layers into bead models, later-formed bead models adjoining earlier-formed bead models are arranged so as to have an area of overlap with the earlier-formed bead models. Further, of the vertices at either end of the bottom segment of the later-formed bead models, with the vertex on the side farther from the area of overlap as the center point, the other three vertices except for the center point are each rotationally shifted, altering the form of the trapezoidal bead models.

Abstract: The present application discloses a vaporizing apparatus for vaporizing a liquefied gas by a way of heat exchange between the liquefied gas and heating liquid. The vaporizing apparatus includes a heat transfer panel including a plurality of heat transfer tubes standing and horizontally lining up for guiding the liquefied gas; a trough for supplying the heating liquid to an outer surface of each of the plurality of heat transfer tubes; and a manifold having an outflow port from which the heating liquid to be supplied to the trough flows out. The trough includes a bottom wall extending in the lining-up direction of the plurality of heat transfer tubes, and a first end wall and a second end wall respectively extending upward at positions away from each other in the lining-up direction of the plurality of transfer panels. The first end wall has an inflow port for allowing the heating liquid to flow in. The manifold is attached to the first end wall.

Abstract: A quality control method for an additively manufactured object includes: a step of acquiring a limit value of a stress intensity factor of the additively manufactured object; a step of obtaining an allowable defect dimension of a defect present in the additively manufactured object by using a variation range of a load stress assumed in design of the additively manufactured object and a condition value including the limit value; a step of setting, as a defect dimension, any one of a predicted value of a defect dimension of a defect that is capable of being generated in the additively manufactured object when the additively manufactured object is manufactured based on the building plan and a measured value of a defect dimension of a defect generated in a test specimen manufactured based on the building plan; and a step of comparing the defect dimension with the allowable defect dimension to determine quality of the beads or the additively manufactured object.

Abstract: The present invention sets a target shape from three-dimensional shape data of a stacked structure and divides the set target shape into a plurality of bead models having shapes corresponding to welded beads. An amount of a filler material that drips down to a lower layer during bead formation in a bead stacking section in which the divided bead models are stacked in the top-to-bottom direction is predicted in accordance with welding conditions for the welded beads. Respective bead heights of the bead models in the bead stacking section are corrected in accordance with the predicted dripping amount. A stacking plan for modeling the stacked structure is created by employing a plurality of bead models including the bead models having the corrected heights.
