The current holy grail of additive manufacturing is to build entire systems (e.g. engines, wings) rather than parts. As the cost of 3D printing declines, it will become possible to make the additive machines bigger and more relevant to weapon manufacturing. By 2020, a majority of parts for aircraft engines are created using additive manufacturing. Smaller countries leverage this technology and other advanced industrial techniques to enhance their ability to create next-generation military capabilities and produce them in quantity.
