摘要： A lamination molding method, which repeats a material layer forming step of forming a material layer and a solidifying step of irradiating an irradiation region of the material layer with laser beams scanned by n scanners to form a solidified layer, includes: a first dividing step and an irradiation order deciding step. In the first dividing step, the irradiation region is divided to 2n-1 or more divided regions by a plurality of first dividing lines in a manner that irradiation time of each of the divided regions to which the laser beams are simultaneously irradiated becomes equal. In the irradiation order deciding step, an irradiation order of the divided regions in the solidifying step is decided in a manner that the laser beams are simultaneously irradiated to the divided regions that are not adjacent, and the laser beams are not simultaneously irradiated to the divided regions that are adjacent.

摘要： A lamination molding apparatus 10 includes a powder layer forming apparatus 20, a recoating head 30, a servo motor 16, a laser irradiating device 40, a numerical control apparatus 52, a laser control apparatus 54 and a computer aided manufacturing (CAM) system 56. The blade 31 moves in the horizontal axis direction so as to form the powder layer on a predetermined molding region. The laser control apparatus 54 controls the laser irradiating device 40 and calculates an irradiation range of a laser beam for every powder layer. The numerical control apparatus 52 obtains data of the irradiation range from the laser irradiating device 40 and outputs a move command such that the blade 31 moves at a feed speed faster than a pre-set feed speed adapted for recoating, in the molding region outside of the irradiation range.

摘要： A calibration method of an additive manufacturing apparatus includes an irradiation trace forming step, an imaging step, a specifying step, and a correction step. The irradiation trace forming step scans laser beams with each of a plurality of scanners with respect to a plurality of target positions on a calibration plate installed on a molding region, and forms a plurality of irradiation traces having different shapes for each of the plurality of scanners. The imaging step simultaneously images the plurality of irradiation traces formed with respect to the same target position. The specifying step specifies a plurality of irradiated positions of the laser beam scanned by each of the plurality of scanners. The correction step generates correction data that specifies a deviation amount at any point of a laser coordinate system related to each of the plurality of scanners.

摘要： A stress controlled layer is constituted to include a compressive stress applied part that is a region to which a compressive stress is applied and a compressive stress non-applied part that is a region different from the compressive stress applied part. In a solidifying step, scanning of a laser beam or an electron beam is performed while a scanning direction for the compressive stress applied part is different from a scanning direction for the compressive stress non-applied part such that the compressive stress applied part expands further than the compressive stress non-applied part or the compressive stress non-applied part shrinks compared with the compressive stress applied part based on a relationship between the scanning direction and an expansion quantity or a shrinkage quantity at a time of temperature change or at a time of heat treatment.
