U.S Navy has introduced new technical guidelines this month to integrate 3D printing into the design, manufacturing, maintenance and repair of its submarines.
Additive manufacturing is faster, cheaper and more reliable than traditional supply chains and production methods, where parts are first produced and then tested.
It also requires several approvals and changes in design, which increase costs and delays in construction.
In 3D printing, changes can be made simultaneously, and expenses are significantly reduced, which makes it perfect for incorporation into U.S defense and shipbuilding strategy.
According to the Project Peculiar Document (PPD) 802-8436658, the Navy will replace parts, earlier built using conventional techniques, with those that would be 3D printed.
Vice Admiral Robert Gaucher, Director of Submarine Programs, said that the shift is vital to unlock 21st-century tech for the benefit of the country’s defence sector so submarines can be built rapidly and delivered on schedule.
He also added that additive manufacturing allows the sector to rise above the supply chain issues and shortage of parts and
