The U.S. Navy has long valued the potential of additive manufacturing (AM) and 3D Printing.AM refers to the depositing of material layer by layer to create an object. For the Navy, it’s not practical to carry every replacement part for every system on a ship, and it can be difficult to forecast if or when parts will fail. AM provides a flexible source of supply in being able to make parts instead of ordering them and waiting for them to arrive, especially for warships at the far end of the supply chain.
