Additive manufactured components including sacrificial caps, and methods of forming components including sacrificial caps are disclosed. The additive manufactured components may include a body portion including a first surface, and a feature formed in the body portion. The feature may include an aperture formed through the first surface of the body portion. Additionally, the components may include a sacrificial cap formed integral with at least a portion of the first surface of the body portion. The sacrificial cap may include a conduit in fluid communication with the feature. The sacrificial cap including the conduit may be removed from the body portion to expose the first surface and the aperture of the feature, respectively, after performing one or more post-build processes, such as shot peening, on the component and the sacrificial cap.
