The propeller is claimed to be the biggest metal 3D-printed propeller ever manufactured with its 2.5-meter span backed by five 200-kg blades. BV also states that it was the first to equip a naval ship in operation with additive manufacturing technology.

"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 and verify the quality records and test reports," BV stated in an announcement.
