A section of a next-generation marine propeller blade has been successfully 3D printed as part of the Digitally Enabled Efficient Propeller (D.E.E.P) project, a seven-month feasibility program exploring additive manufacturing for maritime propulsion. The component was produced using wire arc additive manufacturing (WAAM) in Nickel Aluminium Bronze (NAB), with the milestone marking progress toward lighter, more efficient, and digitally integrated ship propulsion systems. The project is led by Enki Marine Ltd , a marine engineering company focused on propulsion system integration and commercialization, and brings together partners including DEEP Manufacturing Ltd , Stone Marine Propulsion , TWI , Authentise , ASTM International , and Newcastle University . The consortium spans expertise in design, materials testing, digital workflows, certification, and hydrodynamic validation. WAAM 3D printed metal component showing layered deposition structure.
