A method for inspecting a component made using an additive manufacturing process, the component having an internal conduit, is disclosed. In various embodiments, the method includes the steps of: attaching a fluid-blocking header to the component, the fluid-blocking header having an internal conformal surface configured to mate with an external conformal surface of the component; introducing a plugging media into the internal conduit; activating the fluid-blocking header to freeze the plugging media in a vicinity of the fluid-blocking header; pressurizing the internal conduit of the component; and analyzing a fluid flow characteristic at an outlet of the component to assess an occurrence of a blockage within the internal conduit.
