Title:
LAMINATED MOLDED OBJECT PRODUCTION METHOD AND PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/003899
Kind Code:
A1
Abstract:
The present invention creates a lamination plan for each layer in a layer-separated shape of three-dimensional shape data, said plan stipulating both a formation trajectory in which metal is melted, solidified, and formed and heating conditions for the metal. When molding a laminated molded object using this lamination plan, the lamination plan is corrected until the difference between the shape of the laminated molded object that is heat shrunk after lamination and the shape of the three-dimensional shape data is within a predetermined tolerance. The laminated molded object is lamination-molded on the basis of this lamination plan having the difference within said tolerance.
