[Purpose] To achieve efficiently forming powder layers by improving the squeegee sliding speed in a three-dimensional object shaping method. [Solution Means] A three-dimensional object shaping method comprising: a powder layer forming step, sliding step of a squeegee on the supplied powder, and a sintering step of irradiating the powder layer, are successively repeated, wherein after dividing shaping regions into a plurality of laminating units, each laminating unit of the plurality of laminating units are divided into inside region including the maximum prearranged sintering region, and outside region not including the maximum prearranged sintering region, and wherein the squeegee sliding speed in the outside region is set to be greater than the sliding speed in the inside region.
[Objectif] Parvenir à former de façon efficace des couches de poudre en améliorant la vitesse de glissement de la raclette dans un procédé de façonnage dobjets tridimensionnels. [Méthode de solution] Linvention porte sur un procédé de façonnage dobjets tridimensionnels comprenant : une étape de formation dune couche de poudre, une étape de glissement dune raclette sur la poudre ainsi obtenue et une étape de frittage consistant à irradier la couche de poudre, successivement répétées, pendant lesquelles, après division des zones de formage en une pluralité dunités de stratification, chacune des unités de stratification faisant partie de cette pluralité dunités de stratification est divisée en une zone interne comprenant la zone de frittage maximale préparée à lavance et une zone externe excluant la zone de frittage maximale préparée à lavance, où la vitesse de glissement de la raclette dans la zone externe est réglée pour être plus rapide que la vitesse de glissement de la raclette dans la zone interne.
