I could imagine some technology that takes advantage of future layers not being there yet to validate the most recent layer on the same pass, and the one that the current layer will be built upon (as that might have suffered in the time since it has been laid) in a way that is exclusive to this manufacturing method. But as you move to bigger and bigger one-piece parts, you would probably also want your process to support undoing a few layers on failure detection to forego scrapping the whole part.
