Additive Manufacturing (AM) use within the shipbuilding industry presents unique advantages when compared to traditional manufacturing methods (i.e., forgings and castings). The potential for AM to impact shipbuilding will be briefly reviewed. A review of standard material offerings for laser powder bed fusion machines has identified an opportunity to explore new materials that are applicable to marine environments. Nickel copper alloys are not commonly available within the AM industry; however, these materials are widely used within the shipbuilding industry due to their resistance to corrosion and potential biofouling resistance. This presentation highlights an approach to the development of a nickel copper alloy on a 3D Systems ProXTM DMP 320. The team’s investigations will be presented including feedstock analysis, deposition investigations and lessons learned associated with processing the material. Shipbuilding is rapidly accelerating its adoption of AM. The ability to process marine alloys, specifically nickel copper, will reinforce adoption of this technology within the shipbuilding industry.
