A cooling article and method of forming a cooling article are provided. The cooling article includes a body portion separating an inner region and an outer region, an aperture in the body portion, the aperture fluidly connecting the inner region and the outer region, and a reinforcing feature extending at least partially along the body portion, the reinforcing feature being oriented with respect to a build direction. The method includes forming a body portion defining an inner region and an outer region, forming at least one reinforcing feature concurrently with the forming of the body portion, the at least one reinforcing feature extending at least partially along the body portion, and forming an aperture in the body portion, the aperture fluidly connecting the inner region to the outer region. The forming the body portion, forming the aperture, and forming the at least one reinforcing feature comprises additive manufacturing.

1. An impingement sleeve, comprising: a body portion separating an inner region and an outer region of the impingement sleeve;a plurality of apertures in the body portion, the plurality of apertures fluidly connecting the inner region and the outer region; anda reinforcing feature extending from the body portion into the inner region;wherein the impingement sleeve is formed by additive manufacturing; andwherein the reinforcing feature includes a shape selected from the group consisting of T, L, I, F, E, and combinations thereof. 2. The impingement sleeve of claim 1, wherein the reinforcing feature includes at least one cooling feature formed thereon. 3. The impingement sleeve of claim 2, wherein the cooling feature is selected from the group consisting of a cooling hole, a cooling channel, and a combination thereof. 4. The impingement sleeve of claim 1, further comprising at least one additional reinforcing feature. 5. The impingement sleeve of claim 4, wherein a spacing is varied between features selected from the group consisting of the reinforcing feature, the at least one additional reinforcing feature, and a combination thereof. 6. An impingement sleeve, comprising: a body portion separating an inner region and an outer region of the impingement sleeve;a plurality of apertures in the body portion, the plurality of apertures fluidly connecting the inner region and the outer region;a first reinforcing feature extending from the body portion into the inner region; andat least one additional reinforcing feature selected from the group consisting of an external reinforcing feature and an integral reinforcing feature;wherein the body portion, the plurality of apertures, and the reinforcing feature of the impingement sleeve are formed by additive manufacturing. 7. The impingement sleeve of claim 6, wherein the first reinforcing feature includes at least one cooling feature formed thereon. 8. The impingement sleeve of claim 7, wherein the cooling feature is selected from the group consisting of a cooling hole, a cooling channel, and a combination thereof. 9. The impingement sleeve of claim 6, wherein a spacing is varied between features selected from the group consisting of the first reinforcing feature, the at least one additional reinforcing feature, and a combination thereof. 10. A method of forming an impingement sleeve, the method comprising: forming, by additive manufacturing, a body portion defining an inner region and an outer region of the impingement sleeve;forming, by additive manufacturing, a plurality of apertures in the body portion, the plurality of apertures fluidly connecting the inner region and the outer region; andforming, by additive manufacturing, a first reinforcing feature with the forming of the body portion, the first reinforcing feature extending from the body portion into the inner region and including a shape selected from the group consisting of T, L, I, F, E, and combinations thereof. 11. The method of claim 10 further comprising forming at least one cooling feature on the first reinforcing feature. 12. The method of claim 11, wherein the cooling feature is selected from the group consisting of a cooling hole, a cooling channel, and a combination thereof. 13. The method of claim 10, further comprising forming, by additive manufacturing, at least one additional reinforcing feature with the forming of the body portion. 14. The method of claim 13 further comprising varying a spacing between features selected from the group consisting of the first reinforcing feature, the at least one additional reinforcing feature, and a combination thereof, during additive manufacturing. 15. The method of claim 13 further comprising orienting the at least one additional reinforcing feature to a build direction of the additive manufacturing to provide support to the body portion during the additive manufacturing of the impingement sleeve. 16. The method of claim 10 further comprising orienting, arranging, and disposing the first reinforcing feature with respect to a build direction of the additive manufacturing to provide support to the body portion during the additive manufacturing of the impingement sleeve. 17. The method of claim 10 further comprising removing the first reinforcing feature from the impingement sleeve.
