3D Systems is to develop a corrosion performance design guide for the direct metal printing of nickel alloys that could help to reduce maintenance costs in the shipbuilding industry.

 .

The company has been awarded a contract by America Makes and the Department of Defense (DoD) and will collaborate with Newport News Shipbuilding, Northrop Grumman Innovation Systems and corrosion experts at the University of Akron. Together, the organisations will gather corrosion data and explore how additively manufactured components can be finished so as to limit deterioration caused by saltwater.

This research and development programme has been commissioned to address the U.S. Navy’s yearly $8.5 billion corrosion-specific maintenance costs. Corrosion is said to be accelerated when parts have gone through heat treatment and machining processes […]
