Abstract
(EN)
[Problem] To provide a manufacturing method for an additively manufactured body with which the occurrence of a defect in the additively manufactured body can be suppressed. [Solution] The present invention has: an additive manufacturing step for shaping an additively manufactured body 7 under a heating state; and a mechanical processing step for processing the additively manufactured body 7 while maintaining the heating state. In the present invention, it is possible to shape the additively manufactured body 7 by repeating a plurality of times the additive manufacturing step and the mechanical processing step. The heating state is maintained also in the additive manufacturing step and the mechanical processing step which are repeated a plurality of times.

La présente invention a pour but de fournir un procédé de fabrication pour un corps fabriqué de manière additive qui permet de supprimer l'apparition d'un défaut dans le corps fabriqué de manière additive. À cet effet, l'invention comprend : une étape de fabrication additive consistant à façonner un corps fabriqué de manière additive (7) dans un état de chauffage ; et une étape de traitement mécanique consistant à traiter le corps fabriqué de manière additive (7) tout en maintenant l'état de chauffage. La présente invention permet de façonner le corps fabriqué de manière additive (7) en répétant une pluralité de fois l'étape de fabrication additive et l'étape de traitement mécanique. L'état de chauffage est également maintenu pendant l'étape de fabrication additive et l'étape de traitement mécanique qui sont répétées une pluralité de fois.
