Over 400 convene at 2025 Cold Spray and Large-Scale Additive Manufacturing Conference
June 23, 2025
Solvus Global, a technology solution provider for materials and manufacturing based in Leominster, Massachusetts, USA, hosted the 2025 Action Team Event from May 20-22 at the DCU Center in Worcester. Drawing upwards of 400 participants from more than 40 countries, the event united university researchers and industry leaders for the Cold Spray Action Team (CSAT) and Large-Scale Additive Action Team (LSAAT) conferences, which continue to serve as global platforms for advancing Additive Manufacturing technologies. Due to travel restrictions, government agencies were unable to attend the conference.

Nonetheless, this year’s conference offered a robust agenda with over 50 technical presentations, live demonstrations, and networking events, all designed to spark innovation, foster collaboration, and accelerate real-world application of advanced manufacturing technologies such as Cold Spray Additive Manufacturing.
CSAT 2025 opened with a keynote by Dr Victor Champagne, reflecting on the evolution and future of Cold Spray Additive Manufacturing. “In the early 2000s, we were making simple parts but now the technology has progressed from hardware to software to institute controls to materials development; we started off with nonstructural repairs, graduated to structural repairs, then off to Additive Manufacturing. Next, [the Cold Spray community] wants to formalise data acquisition and data management to grow the ecosystem and further accelerate our advancements.”
Key CSAT presentation sessions explored materials in extreme environments, advanced repair applications, nitrogen-based Cold Spray development, and new quality control approaches. Live discussions also explored in-situ sensing, process standardisation, and scaling Cold Spray AM for aerospace and energy components, positioning Cold Spray as a maturing solution for industrial-scale repair and manufacturing.
LSAAT 2025 showcased the growing impact of Directed Energy Deposition (DED), additive friction stir deposition (ASFD), and Cold Spray on critical infrastructure, defence logistics, and space manufacturing. With sessions moderated by experts from Pacific Northwest National Laboratory (PNNL), HAMR, and EWI, the conference emphasised cross-process integration, material qualification, and production scaling. Technical leaders from organisations such as Boeing, Oak Ridge National Laboratory (ORNL), AML3D, and Ohio State University presented compelling case studies showing how additive processes are being adopted for field-repairable artillery, oil and gas infrastructure, and aerospace components.
The 2025 Action Team Event also featured an academic poster competition comprised of 22 students and postdoctoral fellows from institutions including Northeastern University, Worcester Polytechnic Institute (WPI), Florida International University (FIU), and Baylor University. Awards were presented during the closing ceremonies, recognising excellence in research and innovation.
Over 25 exhibitors representing a wide range of sponsors, from leading OEMs to emerging startups, lined the concourse and exhibit halls with state-of-the-art technologies and equipment. VRC Metal Systems, Titomic, and SPEE3D were among the sponsors who showcased full-scale parts, tooling systems, diagnostic platforms, and feedstock materials, offering attendees a tangible look at the field’s progress and practical applications.
With strong sponsorship from OEMs and local vendors, CSAT and LSAAT 2025 exemplified the dynamic growth of the Additive Manufacturing ecosystem. As both communities expand their focus from lab-scale feasibility to scalable, real-world deployment, the 2025 Action Team Event reinforced the vital role of shared knowledge and cross-sector collaboration in Cold Spray and large-scale additive technologies.
