STARNBERG, Germany, Apr 1, 2026 – ACMI is the first organization worldwide to acquire the AMCM M 8K system, marking a significant milestone in large-format metal additive manufacturing. The American Center for Manufacturing and Innovation (ACMI) plays a vital role in reinforcing the United States’ industrial base through targeted investments in emerging businesses across critical sectors.

With the AMCM M 8K, ACMI enables its supply chain partners and customers to manufacture large-volume components on a platform built on proven technology, enhanced by intelligent new features such as AirSword gas flow technology, Dynamic Scan Fields, and advanced beam shaping solutions. Together, these innovations set new benchmarks for quality, productivity, and process reliability.

Defining a New Category in Large-Frame Metal Additive Manufacturing 

The AMCM M 8K, developed by AMCM – the customization specialist of EOS – defines an entirely new category of large-frame laser powder bed fusion (LPBF) metal additive manufacturing. Engineered specifically for high-end aerospace and defense applications. At its core, the DNA of the M 8K combines an expansive build volume of 800 × 800 × 1,200 mm with uncompromising precision, setting a new standard for ultra-large LPBF production.

Powered by eight US-made 1.2 kW nLIGHT lasers, advanced optical systems, and state-of-the-art thermal management, the AMCM M 8K delivers exceptional precision and stability during extended build jobs. Its innovative cooling architecture and optimized process gas flow ensure consistent part quality, even when processing demanding materials such as copper alloys. Designed for both scalability and performance, the system enables the efficient production of complex, mission-critical components including rocket engines and missile structures.

Precision Meets Four Tons of Powder 

With the AMCM M 8K, AMCM has successfully transferred the renowned precision of its M 4K system to a significantly larger platform. The machine moves up to four tons of powder along the Z-axis with maximum accuracy. Eight lasers operate simultaneously across the powder bed with the same high level of precision, enabling the creation of highly intricate structures even in the largest and most demanding components. 

Enabling Ultra-Large LPBF with AirSword Gas Flow Technology 

Scaling LPBF technology to build volumes of one meter and beyond has long posed challenges, particularly in maintaining consistent gas flow and part quality. While alternative additive manufacturing methods such as Directed Laser Deposition offer large build sizes, they often do so at the expense of precision.

AMCM’s breakthrough solution is AirSword™, implemented in the AMCM M 8K and the upcoming M 10K. AirSword™ is a precision-engineered gas flow system designed specifically to address the airflow challenges of ultra-large LPBF builds. It ensures uniform, multi-layered gas flow across the entire building area, eliminates laser-smoke interaction for clean and reliable processing, protects optics and laser paths during long-duration jobs, and reduces maintenance requirements while increasing system uptime for high-volume production.

“The AirSword technology allows AMCM to retain the proven fixed-scanner approach, delivering unmatched speed and quality without the added complexity of moving optics.” said, Georg Fey, Team Manager Application & Innovation at AMCM

Dynamic Scan Fields: Intelligent Exposure for Maximum Flexibility

The AMCM M 8K is powered by EOSPrint, featuring the new Dynamic Scan Fields capability that makes a decisive difference in large-format builds. Large overlap areas introduce unique challenges, and optimal results depend on deliberately choosing how each part is exposed. EOSPrint brings all strategies onto a single platform, giving users full freedom of choice.

Dynamic Scan Fields enable fully automated, layer-dependent optimization in which scan fields adapt dynamically, and lasers work cooperatively rather than in rigid segments, maximizing productivity. For applications requiring predictability and control, options without overlapping or with controlled overlap allow transparent, layer-by-layer collaboration between lasers. Full-field overlap removes rigid quadrant logic entirely, intelligently balancing unevenly populated areas for uniform exposure. Fixed segmentation supports multipart jobs where reproducibility and maximum control are paramount.

Not every process requires full automation, and EOSPrint reflects this reality by supporting all exposure strategies in a flexible, user-driven environment.

Economic and Technological Significance for the U.S. Supply Chain 

ACMI is powering American manufacturing and advancing onshoring initiatives. By expanding domestic production capabilities, the company is reinforcing critical industries and enabling more resilient and dynamic supply chains that can effectively respond to current and future challenges.

In the defense manufacturing sector, ACMI is lowering the barriers to access the latest manufacturing technologies for defense contractors and the broader subcomponent supply chain, helping to accelerate modernization and improve production readiness across the industry.

“With the acquisition of the M 8K, we are providing a world-class capability to our stakeholders that will enable U.S. manufacturers to develop new production strategies, accelerate innovation, and scale more efficiently.” said, John Burer, Founder and CEO of ACMI Group.

“With the acquisition of an AMCM M 290 and the AMCM M 8K, both with nLIGHT technology, in combination ACMI and their customers can utilize a fast-track approach with the same optical set-up and accelerated development timelines. In addition, AMCI benefits from U.S.-based EOS Additive Minds support, for example in process development.” said, Felix Bauer, Director of Sales at AMCM.
