I would like to add that additive manufacturing is still in its infancy, and that there are structures that pay large strength dividends which are impossible to manufacture any other way, such as 3-dimensional honeycombs, which haven't made their way into standard engineering practice yet. But there may come a point where the available design space is so much better that it's worth sacrificing some strength in the material itself.
