In a transformative leap for maritime technology, the U.S. Navy has successfully employed Liquid Metal Jetting (LMJ) 3D printing aboard the USS San Diego, enabling the on-demand production of high-strength aluminium alloy parts. This cutting-edge breakthrough promises to revolutionise how ships maintain their operational readiness, addressing critical repair needs while at sea.
Developed by ADDiTEC, the ElemX 3D printer represents a game-changing advance in maritime innovation. For the first time, essential parts—previously reliant on traditional supply chains—can now be fabricated directly aboard a ship, ensuring quicker repairs and reducing the risks of operational downtime. The recent success aboard the USS San Diego demonstrates that 3D printing technology is not only feasible but highly effective in the challenging environment of active naval missions.
A Breakthrough in Marine Technology
This new capability highlights the U.S. Navy’s ongoing commitment to leveraging advanced technologies to maintain fleet readiness. The ElemX 3D printer uses ADDiTEC’s proprietary LMJ technology, specifically designed for high-strength aluminium alloys like Al-6061. This is no ordinary technology—it’s an innovation capable of producing robust, functional parts that meet the Navy’s rigorous performance standards.
According to Dr. Garth Hobson, Director of the Naval Postgraduate School’s Consortium for Advanced Manufacturing, Research and Education, the technology has exceeded expectations. “The ease of use and the quality of the printed parts exceeded our expectations,” said Hobson. “This technology represents a significant enhancement in our ability to maintain and repair equipment while at sea.”
This development is especially significant for maritime operations, where the ability to print high-strength components directly on board could drastically cut down time lost to repairs, particularly when access to spare parts is limited or during long-term deployments.
Redefining Naval Operations and Logistics
The USS San Diego’s use of the ElemX printer is part of a broader effort to explore the potential of additive manufacturing in the Navy’s logistical framework. This technology could reduce the reliance on traditional supply chains—a critical advantage in contested or remote environments.
For maritime operations, the benefits extend beyond just military applications. Commercial shipping, offshore installations, and long-range yachts could similarly benefit from on-board 3D printing technology. Imagine being able to fabricate a replacement part for a vessel while mid-ocean, eliminating the need to wait for supplies or navigate to port.
ADDiTEC, the company behind this innovative 3D printer, has worked meticulously to meet the stringent requirements of naval operations. The ElemX is containerised, meaning it can be easily deployed aboard ships and in maritime environments. The ability to print durable aluminium components while at sea offers a glimpse into the future of maintenance, not only for the Navy but for all types of maritime operations.
Collaborative Innovation at Sea
The Naval Postgraduate School and the Consortium for Advanced Manufacturing, Research and Education have been key players in driving this advancement, researching and testing the ElemX 3D printer’s performance in various scenarios. By allowing the Navy to print on-demand parts, this collaboration has directly addressed long-standing logistical challenges and boosted fleet readiness.
ADDiTEC CEO Brian Mathews echoed the excitement of this breakthrough: “We have worked tirelessly to ensure our 3D printing technologies meet the specific needs of maritime operations. Seeing our efforts come to fruition with the successful printing of functional parts at sea is incredibly rewarding. We remain committed to advancing this technology for the Navy’s needs.”
What This Means for the Future of Boating
For the broader marine industry, this innovation could mark the beginning of a new era. Whether it’s a commercial vessel, a recreational yacht, or a military ship, the ability to produce custom parts at sea will drastically change how repairs are managed. As technology develops, we could see 3D printing become a regular fixture on many types of vessels.
As the world watches this exciting development unfold, it’s clear that the success of the ElemX 3D printer is more than just a technological achievement—it’s a testament to the future possibilities for the maritime industry, providing new solutions for the ever-evolving challenges faced on the open sea.
