World leader in testing, inspection, and certification Bureau Veritas has certified a new-generation 3D printed propeller manufactured by Naval Group. With its 2.5-metre span supported by five 200-kg blades, Naval Group manufactured this new-generation propeller thanks to a metal 3D printing process. Mounted on a Tripartite-class minehunter, the propeller will now accompany the ship on all of its operational missions.
The propeller is a technological achievement, as the largest metal 3D-printed propeller ever manufactured, and the first one made using additive manufacturing technology to equip a military ship in operation.
Obtaining military naval quality requires rigorous development. Bureau Veritas has been involved at every step of the manufacturing and testing process. Building on our technical expertise and innovation capabilities in 3D printing technology for the maritime industry, we worked closely with Naval Group throughout the process to:
Define the qualification plan for the process
Define the production testing and inspection plan for the 3D printed parts
Witness manufacturing steps and testing
Verify the quality records and test reports
