The realm of military logistics is undergoing a significant transformation, thanks to innovations in additive manufacturing. SPEE3D, an Australian metal 3D printing company, recently showcased the practical applications of its Cold Spray Additive Manufacturing (CSAM) technology in a critical demonstration organized by the U.S. Army Combat Capabilities Development Command (DEVCOM) Army Research Laboratory (ARL) at the University of Tennessee Knoxville. This two-week exercise, held from August 5-16, 2024, aimed to assess the feasibility of producing essential components in field conditions, ultimately supporting military operations in real-world scenarios.A New Era in Additive ManufacturingThe field test focused on evaluating the capabilities of SPEE3D’s WarpSPEE3D printer, which utilizes a patented Supersonic 3D Deposition process. This innovative method accelerates air to supersonic speeds, allowing metal powders to rapidly bond together, forming dense, solid parts without the need for traditional heat-based melting processes. The result is a robust solution for creating high-density components on-site, directly addressing logistical challenges often encountered in military operations.One of the remarkable aspects of this demonstration was the training of a soldier with no prior experience in additive manufacturing. Within just a week, the soldier was proficient in operating the WarpSPEE3D printer, illustrating the accessibility and practicality of the technology. This rapid training highlights the potential for on-demand manufacturing solutions in military settings, where operational readiness is critical.A Successful Field TestDuring the demonstration, the soldier successfully 3D printed a transmission mount for a Bradley Fighting Vehicle, a vital component essential for maintaining the vehicle's operational status. After installation, the part underwent rigorous field testing by the 278th Armored Cavalry Regiment. The results were promising: after multiple test cycles, the component was found to be intact, confirming the reliability and effectiveness of SPEE3D’s technology in producing dependable parts in challenging environments.Byron Kennedy, CEO of SPEE3D, emphasized the significance of the exercise: “Training a soldier with no previous additive manufacturing experience to produce a vital component within a week demonstrates the practical application of our technology in military scenarios. This capability is crucial for providing on-demand solutions where they are most needed.”Michael Nicholas, a Materials Engineer at DEVCOM ARL, noted, “This demonstration showed how cold spray technology can be used to enhance logistical capabilities in expeditionary environments. Such systems are vital for overcoming supply chain challenges, particularly in contested logistics environments.”Integration into U.S. Military OperationsThe success of the demonstration aligns with SPEE3D’s increasing integration into U.S. military operations. At RIMPAC 2024, the largest international naval exercise, the WarpSPEE3D printer was deployed to produce mission-critical components on-site. This system not only enables military personnel to manufacture durable parts in the field but also mitigates the logistical complexities typically associated with conventional manufacturing methods.In a separate exercise, SPEE3D’s technology played a central role in the U.S. Navy’s first SALVEX exercise at Pearl Harbor in May 2024. The XSPEE3D and SPEE3Dcell units were utilized to produce critical replacement parts in a simulated naval damage control scenario. The XSPEE3D, housed within a mobile unit, enabled the rapid printing of metal parts up to 1m x 0.7m using materials such as aluminum and stainless steel. Combined with the SPEE3Dcell unit for post-processing, this setup provided the Navy with a robust solution for manufacturing essential components under operational conditions—an invaluable capability in situations where supply chain disruptions could jeopardize mission success.Looking AheadThe recent demonstration of SPEE3D’s Cold Spray Additive Manufacturing technology marks a pivotal moment in the future of military logistics. As the U.S. Army and Navy increasingly adopt innovative manufacturing solutions, SPEE3D stands at the forefront, showcasing the potential for on-demand production of critical components in the field. With ongoing advancements and successful field tests, the integration of 3D printing technology into military operations is set to revolutionize the way armed forces operate, ensuring they remain agile and effective in various environments.
