Army’s Battle Damage Repair and Fabrication program extends Jointless Hub applications
The massive metal 3D printer leverages friction stir welding AM technology to produce vehicle spare parts

Additive manufacturing (AM) is revolutionizing military logistics by enabling the rapid production of critical vehicle components. The U.S. Army’s Battle Damage Repair and Fabrication (BDRF) initiative is leveraging the Jointless Hub metal 3D printing system to minimize downtime, extend the lifespan of ground vehicles, and enhance operational readiness. This initiative represents a major shift in how the Army sustains its fleet, ensuring that vehicles remain mission-capable even in challenging conditions.
Additive manufacturing is reshaping the military supply chain by providing on-demand production capabilities. This technology allows for quickly replacing damaged parts, eliminating the need for long and complex procurement processes. With the ability to print parts directly where needed, the Army can reduce logistical challenges and keep vehicles operational for longer periods, even in forward-deployed locations.
The Battle Damage Repair and Fabrication (BDRF) Program
The BDRF program is a collaborative effort involving key Army organizations, including the U.S. Army DEVCOM Ground Vehicle Systems Center (GVSC), TACOM, and Rock Island Arsenal. This program uses additive manufacturing to produce temporary replacement parts for damaged vehicles. By bridging the gap between part failure and traditional supply chain fulfillment, the BDRF initiative enhances readiness. It ensures that battle-damaged cars can return to the field without extended downtime.
The success of additive manufacturing in military applications depends on the use of advanced materials. The Army employs high-strength metals, polymers, and composite materials to ensure durability and reliability in battlefield conditions. Metal additive manufacturing, in particular, has proven effective in producing strong and resilient components. These materials undergo rigorous testing to verify that they meet or exceed the performance of traditionally manufactured parts.

The Jointless Hull subsection tool
The Jointless Hull subsection tool represents a significant advancement in hybrid metal additive manufacturing. Located at the Advanced Manufacturing Commercialization Center (AMCC), this tool supports the full-size Jointless Hull machine at Rock Island Arsenal, developed in collaboration with Ingersoll (for the architecture) and MELD (for the friction stir welding AM process). By enabling the production of large-scale vehicle components, this technology enhances the Army’s ability to manufacture durable and high-performance parts efficiently.
One key advantage of additive manufacturing is its ability to rapidly produce parts using 3D CAD models. The Army has already assessed more than 40,000 vehicle components, leading to the development of over 600 digital designs that can be manufactured on demand. Parts are scanned, uploaded to a database, and printed when needed, drastically reducing the time required for replacement. This process is particularly valuable for components that have long procurement lead times or have become obsolete.
Additive manufacturing plays a crucial role in sustaining the lifecycle of military vehicles. Many older platforms suffer from parts obsolescence, making finding suitable replacements through traditional supply chains difficult. By utilizing 3D printing, the Army can fabricate temporary replacements, keeping vehicles in service while permanent solutions are identified. This approach ensures continued operational readiness and reduces costs associated with full system replacements.
Collaboration between Army R&D and industry partners
The success of the BDRF program is largely due to the collaboration between various Army research and logistics centers, as well as industry partners. GVSC leads research and development efforts, TACOM oversees logistics integration, and Rock Island Arsenal executes manufacturing. The cooperation between these entities allows for seamless integration of additive manufacturing into the Army’s sustainment strategy. Additionally, partnerships with private sector manufacturers contribute to innovation and further development of this technology.
The Army is actively working to bring additive manufacturing closer to the battlefield by deploying mobile 3D printing labs. These units enable soldiers to produce replacement parts in remote locations, reducing the need for extensive supply chains. In combat zones, where logistics can be severely disrupted, the ability to print necessary components on-site significantly improves readiness and mission capability.
In some cases, 3D printed parts have been shown to outperform original manufacturer components. Several temporary replacement parts produced under the BDRF program have undergone rigorous testing and have demonstrated superior durability. As a result, some of these parts have been submitted for consideration as permanent secondary sources of supply. This shift highlights the potential for additive manufacturing to replace and enhance military vehicle components.
The future of additive manufacturing in army sustainment
The Army is continuing to expand its additive manufacturing capabilities, with plans to enhance the role of the AMCC in engineering builds and limited component testing. Future advancements may include integrating artificial intelligence and machine learning to optimize part design and production. By continuously improving these capabilities, the Army aims to streamline sustainment operations further and improve efficiency across the entire logistics network.
Despite its advantages, additive manufacturing faces challenges in scaling production to meet the Army’s needs. Security concerns regarding digital part designs and the potential for cyber threats must also be addressed. Additionally, regulatory compliance and quality control are critical to ensuring that 3D printed parts meet military standards. Overcoming these challenges requires continued investment in research, workforce training, and cybersecurity measures.
While initial investments in additive manufacturing technology can be high, the long-term cost savings are significant. By reducing reliance on traditional supply chains, the Army can minimize costs associated with procurement, storage, and transportation of spare parts. Additionally, producing components on demand reduces waste and improves overall resource efficiency.
To fully leverage additive manufacturing, the Army is investing in training programs for personnel. Soldiers and sustainment teams are being educated on how to operate 3D printing equipment, while research collaborations with universities and industry partners are helping to develop new expertise. Upskilling efforts ensure that the workforce remains prepared to integrate AM technology into daily operations.
