PROBLEM TO BE SOLVED: To provide an article integrally formed as a single continuous article, and a method of forming the article using an additive manufacturing technique.SOLUTION: An article is disclosed including a manifold, an article wall, a post-impingement cavity and a plurality of post-impingement partitions. The manifold includes an impingement wall defining a plenum and a plurality of impingement apertures. The article wall includes a plurality of external apertures. The post-impingement cavity is disposed between the manifold and the article wall, and is arranged to receive a fluid from the plenum through the plurality of impingement apertures and exhaust the fluid through the plurality of external apertures. The plurality of post-impingement partitions divide the post-impingement cavity into a plurality of sub-cavities, and hermetically separate the plurality of sub-cavities from one another. The impingement wall, article wall and a plurality of post-impingement partitions are integrally formed as a single continuous article.SELECTED DRAWING: Figure 1 【課題】単一の連続物品として一体的に形成された物品、並びに付加製造技法を利用した物品の形成方法を提供する。【解決手段】マニホルド、物品壁、インピンジメント後キャビティ、及び複数のインピンジメント後区画を含む物品が開示される。マニホルドは、プレナム及び複数のインピンジメントアパーチャを定めるインピンジメント壁を含む。物品壁は、複数の外部アパーチャを含む。インピンジメント後キャビティは、マニホルドと物品壁との間に配置され、複数のインピンジメントアパーチャを通ってプレナムから流体を受け取り、複数の外部アパーチャを通って流体を排出するよう構成される。複数のインピンジメント後区画は、インピンジメント後キャビティを複数のサブキャビティに分割して、複数のサブキャビティを互いに気密分離する。インピンジメント壁、物品壁、及び複数のインピンジメント後区画は、単一の連続した物品として一体的に形成される。【選択図】 図１
