We invite you to join our Webinar on the "Development of Metal Additive Manufacturing for Naval Shipbuilding" with speaker Dr. Mike Shepard, Vice President of Aerospace & Defense Segment at 3D Systems, and Dr. John Ralls, Manager Principal Engineer at Newport News Shipbuilding (NNS). 

Throughout the webinar, they will discuss about the metal AM opportunity in the naval shipbuilding industry and how it impacts timely delivery of quality hardware. They will share with you their experience on how HII’s Newport News Shipbuilding division anticipates up to 75 percent reduction in lead times and lowered inventory costs by switching over historically difficult CuNi30 castings to a qualified laser powder bed fusion material and process.

In this webinar, you’ll learn about:

  • AM technologies for the shipbuilding industry
  • The need for suitable AM marine alloys
  • The qualification path for AM parts in naval shipbuilding
  • Example application focus areas in shipbuilding
