Additive manufacturing, more commonly understood in the technology world as 3-D printing, is here to stay. Integrating this technology into our fleet and logistical supply chains now could provide incredible benefits, even though the technology still is relatively nascent. The Economist calls this “the third industrial revolution,” and, indeed, these techniques could transform the way we supply materiel in the wars we fight.
Imagine you are a supply officer on a minesweeper and a relatively simple plastic gas cap disappears. Or as the commanding officer of an Arleigh Burke-class destroyer, you discover that a small part of your close-in weapon system breaks and the supply chain has no more. As a submariner, you are on station for three months of deployment only to discover a malfunctioning inexpensive butterfly valve may necessitate aborting the whole mission. What do you do?
These are all true stories. In the first, the Navy spent $400 to ship that $7 gas cap halfway around the world. The destroyer’s commanding officer was forced to complete his deployment without a key defensive system. For the submarine, some enterprising machinist mates found solid copper and banged out a replacement in a matter of minutes that lasted through the end of deployment. All these situations had solutions, but none of them was ideal.
What if each of these vessels had easy access to a 3-D printer or an additive manufacturing capability organic to the ship? What if, instead of waiting six months or more for a high-fail, high-demand plastic part, a replacement could be printed instantaneously, tested and then implemented immediately?
