One of the problems with any metal 3DP process is that unmelted powder can onlty be removed if there is an exit area afer the melting is done. Any holes like those in closed cell foam or Swiss cheese remain filled with unmelted powder. While this might not matter for some parts it makes them heavier and more expensive, not good for aerospace. This probably can be minimized by clever design of the part, leaving adequate channels for powder removal.
