Please join the Hampton Roads Section for a presentation by Dr. John W. Ralls on the development of metal additive manufacturing technology.  

Dr. Ralls will provide a presentation relating to the development of Metal Additive Manufacturing (AM) in Naval Shipbuilding. His presentation will focus on two main areas: the qualification of a stainless steel AM part and the utilization of AM at NNS. This presentation will highlight the AM qualification journey performed for a 316L-AM material, discuss process capability considerations, highlight AM design and build considerations, and briefly discuss material test result examples. Additionally, several examples of AM focus areas for shipyards will be discussed ranging from rapid prototyping to new design potential.
