  • Patent number: 11945031
    Abstract: A method for manufacturing an additively-manufactured object in which deposition is performed by melting and solidifying a metal depending on three-dimensional shape data of a target shape, includes: acquiring the three-dimensional shape data; creating a deposition plan in which a formation track and a heating condition of the metal are determined; determining a difference between a shape of the additively-manufactured object that thermally contracts by cooling after deposition and a shape of the three-dimensional shape data by an operation; modifying the deposition plan until the difference falls within a predetermined allowable range; and additively manufacturing the additively-manufactured object based on the deposition plan in which the difference falls within the allowable range.

  • Publication number: 20220269242
    Abstract: A building time for building an additively-manufactured object is calculated on the basis of the inter-pass time and the welding pass time and is compared with a preset upper limit value, and welding conditions in a depositing plan are repeatedly modified until the building time is equal to or less than the upper limit value. Alternatively, corrections are repeatedly performed until the shape difference between a building shape of built-up object shape data relating to the additively-manufactured object created on the basis of the inter-pass time and the inter-pass temperature, and a building shape of three-dimensional shape data, is smaller than a near net value.

  • Patent number: 11415962
    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.
