EOS, ACMI Deploy World’s First AMCM M 8K

EOS and the American Center for Manufacturing & Innovation (ACMI) have formed a strategic partnership to expand advanced additive manufacturing capabilities across ACMI’s U.S. industrial campus network, with a focus on scaling domestic production for aerospace and defense applications.

The primary technical milestone of the collaboration is ACMI’s acquisition and deployment of multiple EOS and AMCM metal additive manufacturing systems, including the world’s first AMCM M 8K. Additional systems include the newly launched EOS M4 ONYX and an AMCM M 290-2 FLX equipped with beam-shaping technology. Together, these systems significantly expand the size, throughput, and material flexibility available for industrial metal additive manufacturing in the United States.

Developed by AMCM, part of the EOS Group, the AMCM M 8K establishes a new category of large-frame metal additive manufacturing. The system features a build volume of 800 × 800 × 1,200 mm and integrates eight 1.2 kW nLIGHT lasers, advanced optical architectures, and dedicated thermal management. Its cooling and optimized process gas flow are designed to maintain dimensional stability and part quality during long-duration builds, including with demanding materials such as copper alloys. These capabilities enable the production of large, mission-critical components such as rocket chambers, engine injectors, and fuel tanks.




ACMI’s manufacturing model brings together commercial, government, academic, and private-sector stakeholders to accelerate onshoring and production readiness. By integrating EOS technologies into multi-tenant industrial campuses, ACMI aims to support manufacturers from R&D through qualified, full-scale production while addressing national manufacturing security requirements.

EOS contributes its industrial additive manufacturing platforms, materials expertise, and engineering know-how, while ACMI provides the infrastructure and ecosystem needed to deploy these technologies at scale. The partnership is intended to shorten development timelines, increase production capacity, and make previously inaccessible large-format metal AM capabilities available to U.S. manufacturers.

By deploying high-productivity systems such as the AMCM M 8K within shared industrial campuses, the collaboration creates a scalable pathway for adopting additive manufacturing in aerospace, defense, and other advanced manufacturing sectors, strengthening domestic manufacturing resilience and production capability.
