  • Publication number: 20210080931
    Abstract: Using three-dimensional shape data, the shape of a blade, which is an additive manufacturing product, is divided into multiple layers according to the height of a bead. Each layer of the additive manufacturing product that has been divided into multiple layers is divided by fitting regions of a set shape. By determining connecting lines for connecting the divided regions to each other and computing the extension directions of protrusions, planned lines for bead formation along said extension directions are determined. The additive manufacturing product is shaped by forming beads along planned bead formation lines.
