Title (EN) IMPROVED ADDITIVE LAYER MANUFACTURING
(FR) FABRICATION ADDITIVE AMÉLIORÉE
Abstract: front page image
(EN)This invention relates to additive layer manufacturing (ALM) and in particular to a method to minimise residual thermal stress in a component manufactured by powder fed ALM processes, and objects formed therefrom. There is provided a three dimensional object formed by additive layer manufacture, wherein said object is formed from a plurality of sintered material layers of a feed material, wherein said object comprises at least one formed cavity, said cavity substantially filled with a filler material.
(FR)La présente invention concerne la fabrication additive (FA) et, en particulier, un procédé en vue de réduire au minimum la contrainte thermique résiduelle dans un élément fabriqué par des procédés FA alimentés par poudre, et des objets ainsi formés. L'invention porte également sur un objet tridimensionnel formé par fabrication additive, ledit objet étant formé à partir d'une pluralité de couches de matériau fritté d'un matériau d'alimentation, ledit objet comprenant au moins une cavité formée, ladite cavité étant sensiblement remplie d'un matériau de remplissage.
