The Oak Ridge National Laboratory (ORNL), a flagship research institution under the U.S. Department of Energy, recently achieved remarkable recognition at the 2025 Composites and Advanced Materials Conference (CAMX), a premier event in North America dedicated to advancements in composite materials and manufacturing technologies. ORNL’s groundbreaking achievements were honored with four prestigious awards that underscore the laboratory’s leadership in pushing the boundaries of materials science and additive manufacturing.
The accolades began with ORNL receiving the 2025 SAMPE Organizational Excellence Award, an esteemed national recognition bestowed upon organizations demonstrating extraordinary contributions to the advanced materials and processes community. This award reflects ORNL’s multidisciplinary impact across industrial, academic, and governmental sectors, highlighting its vital role in accelerating innovation in composites.
Among the technological breakthroughs celebrated was ORNL’s multiplexing extrusion system, which earned the Equipment and Tooling Innovation Award. This revolutionary additive manufacturing technology integrates multiple 3D printing extruders into a unified high-output manufacturing stream. By leveraging specially engineered nozzles, the system simultaneously deposits multiple materials within a single continuous bead, eliminating the need for frequent equipment swaps or manual retooling. This integration not only accelerates print speed but also enhances precision and material versatility, representing a transformative advance in large-scale composite fabrication.
The multiplexing extrusion system’s design solves critical bottlenecks faced in traditional extrusion-based additive manufacturing. Conventional processes often require sequential material changes that increase downtime and complicate production workflows. ORNL’s approach harmonizes throughput with multi-material capability, enabling complex composite structures with spatially varying material properties to be produced seamlessly. This technology stands to revolutionize sectors such as aerospace, automotive, and energy, where lightweight, multifunctional composite components are increasingly demanded.
In addition to tooling innovations, ORNL’s collaborative research partnership with Electroimpact garnered the Material and Process Innovation Award. This project pioneered the development of composite rocket nozzles using modular, additively manufactured heads combined with assisted large-scale dissolvable tooling. By employing water-soluble molds, the manufacturing process eliminates reliance on traditional machining, harsh solvents, and labor-intensive demolding operations, thereby significantly reducing production costs and lead times.
The use of dissolvable tooling embodies a novel strategy in advanced composites manufacturing. It enables the fabrication of geometrically complex and load-optimized components with minimal post-processing. This innovation not only streamlines production but also expands design freedom, facilitating new possibilities in aerospace propulsion systems and other high-performance applications where precision and weight reduction are paramount.
Robert Wagner, ORNL’s associate laboratory director for the Energy Science and Technology Directorate, emphasized the broader implications of these advances. According to Wagner, ORNL’s pioneering work is pivotal in transitioning carbon fiber and composite technologies from experimental platforms into real-world industrial applications. The technologies emerging from ORNL’s labs are expected to revolutionize sectors ranging from defense and infrastructure to commercial transportation and renewable energy.
Individual excellence in the composites domain was also recognized during the CAMX event. Uday Vaidya, holding the prestigious University of Tennessee-ORNL Governor’s Chair in Advanced Composites Manufacturing, was awarded the Academic Pioneer Award. This accolade honors his visionary research and sustained contributions that have pushed forward engineered plastics and composites technologies. Vaidya’s role as the chief technology officer of IACMI-The Composites Institute has been instrumental in fostering collaborative ecosystems that accelerate composite innovations from concept to commercialization.
CAMX, held this year in Orlando, Florida, is widely regarded as the foremost global exposition and conference for composites and advanced materials. The event serves as a vital forum for disseminating scientific breakthroughs, fostering industrial partnerships, and showcasing cutting-edge manufacturing technologies that define the future of materials engineering.
Many of ORNL’s celebrated innovations at CAMX are supported by the DOE’s Office of Energy Efficiency and Renewable Energy through initiatives such as the SM2ART Program in collaboration with the University of Maine’s Advanced Structures and Composites Center. This funding enables high-risk, high-reward research focused on scalable, energy-efficient manufacturing technologies that strengthen the U.S. position in critical materials and composites.
UT-Battelle, the managing contractor of ORNL, operates the laboratory for the DOE’s Office of Science, the nation’s largest federal supporter of fundamental research in physical sciences. The Office of Science’s sustained investment in foundational and applied research at ORNL underscores a commitment to confronting some of the most pressing scientific and technological challenges of our time.
In summary, ORNL’s multiple awards at CAMX 2025 reflect the laboratory’s unparalleled expertise and innovative capacity in the field of composite materials and additive manufacturing. These advancements promise to accelerate the deployment of next-generation materials solutions across diverse industries, enabling lightweight, multifunctional components with enhanced sustainability and performance. As additive manufacturing technologies continue to evolve, ORNL’s pioneering efforts serve as a beacon for the future of advanced materials innovation.
