Title (EN) METHODS AND MULTI-PURPOSE POWDER REMOVAL FEATURES FOR ADDITIVE MANUFACTURING
(FR) PROCÉDÉS ET ÉLÉMENTS D’ÉLIMINATION DE POUDRE MULTI-USAGE POUR FABRICATION ADDITIVE
Abstract:
(EN) The present disclosure generally relates to methods for additive manufacturing (AM) for fabricating multi-walled structures. A multi-walled structure includes a first wall having a first surface and a second wall having a second surface facing the first surface to define a passage having a width between the first surface and the second surface in a first direction. The multi- walled structure also includes an enlarged powder removal feature connecting the first wall and the second wall. The enlarged powder removal feature has an inner dimension greater than the width in the first direction and at least one open end in a direction transverse to the first width.
(FR) La présente invention concerne de manière générale des procédés de fabrication additive (AM) pour fabriquer des structures à parois multiples. Une structure à parois multiples comprend une première paroi ayant une première surface et une seconde paroi ayant une seconde surface faisant face à la première surface pour définir un passage ayant une largeur entre la première surface et la seconde surface dans une première direction. La structure à parois multiples comprend également un élément d'élimination de poudre élargi reliant la première paroi et la seconde paroi. L'élément d'élimination de poudre élargi a une dimension interne supérieure à la largeur dans la première direction et au moins une extrémité ouverte dans une direction transversale à la première largeur.
