3D Printing at Sea: Reinventing Naval Manufacturing

3D Printing at Sea: Reinventing Naval Manufacturing

27 Nov 2023

In the maritime defence sector, the emergence of 3D printing is creating new avenues for innovation and efficiency. The US Navy's adoption of this technology for submarine hull production in 2017 marked a significant step forward, showcasing the potential for enhancing naval capabilities through advanced manufacturing techniques.

The process of constructing submarine hulls has historically been intricate and time-intensive, involving meticulous craftsmanship and precision. The transition to 3D printing, also known as additive manufacturing, represents a shift towards a more streamlined and precise production method. This technology enables the creation of complex designs and structures that are difficult to achieve with traditional manufacturing, potentially improving the structural integrity and performance of naval vessels.

One of the primary benefits of 3D printing in the defence industry is the significant cost and time savings it offers. The Department of Energy notes a reduction in both production costs, by up to 90%, and manufacturing time—from several months to just days. This efficiency does not compromise quality; instead, it allows for rapid prototyping and testing, which is critical for developing and refining technologies in response to dynamic security challenges.

3D printing also introduces a level of customisation previously unattainable, permitting designs to be tailored to specific mission requirements. Submarines and ships can be optimised for various operational roles, whether it be stealth and reconnaissance or stability for amphibious tasks. This adaptability ensures that vessels are not only versatile but also highly effective for their intended purposes.

Furthermore, the use of 3D printing can lead to a more resilient supply chain. By reducing reliance on a wide network of suppliers and enabling on-site production of components, the technology enhances a nation's self-sufficiency and adaptability, particularly during crises or conflicts when supply chains are most vulnerable.

The US Navy's experience with 3D-printed submarine hulls illuminates the advantages this technology brings to naval defence, with the potential to revolutionise the defence and marine industries. As the technology matures and adoption increases, it could lead to a new standard in naval manufacturing, marked by cost-effectiveness, agility, and the ability to meet evolving maritime challenges with innovative solutions.
