AMCM introduces a new 3D printer with eight lasers for the Prometheus Rocket and establishes a collaboration with Sintavia.


AMCM, a sister company of EOS, has recently introduced its newest metal additive manufacturing machine, the M 8K. Set to be launched by the end of 2024, the M 8K builds upon the success of its predecessor, the M 4K. However, its most notable feature is its first task: printing the combustion chamber for the Prometheus rocket engine developed by the Ariane Group.

Prometheus is a highly anticipated project supported by major European space agencies. It represents the future of reusable and cost-efficient rocket propulsion for space exploration in the upcoming era. The collaboration between AMCM and Sintavia, marked by an agreement signed in September, further solidifies the M 8K’s position in the industry. Sintavia, a leading player in additive design and manufacturing for aerospace and defense, has already had experience with the M 4K system. This partnership signifies a shared vision of leveraging the advanced capabilities of the M 8K platform.

Sintavia’s Founder and CEO, Brian R. Neff, expressed excitement about being the first in North America to utilize the larger build volume of the AMCM M 8K. Having had a positive experience with the M 4K, Neff looks forward to exploring the possibilities of the M 8K in their production. Sintavia plans to integrate its first M 8K into operations by 2025, joining multiple M 4K systems used to create high-value components for aerospace applications.

The M 8K is expected to outshine its predecessor with its impressive specifications. While the M 4K boasted a large build envelope of 450 x 450 x 1000 mm and the integration of four 1kW lasers, the M 8K doubles its firepower with eight lasers. Additionally, it offers an even more significant building volume of 800 x 800 x 1200 mm. According to AMCM, the M 8K embodies precision, innovation, and the ability to meet the demands of complex projects like the Prometheus combustion chamber.

This initiative goes beyond striving for dominance in the metal printing industry; it is a response to the specific needs of high-profile aerospace applications. The Ariane Group identified the necessity for a more substantial build volume, leading to the selection of the AMCM M 8K system for the fabrication of the Prometheus rocket engine’s combustion chamber. AMCM plans to use the EOS copper alloy CuCr1Zr to craft the chamber, which will have a height of over 1,000 mm and a maximum diameter of 800 mm. This represents an unprecedented accomplishment in terms of size and quality.

Jan Alting, Head of Future Propulsion at ArianeGroup, emphasized the critical importance of high-quality parts and praised AMCM for their ability to meet the rigorous standards set by the European Space Agency (ESA). Alting stated that AMCM’s impressive track record and innovative spirit made them the natural choice for such an ambitious venture.

With the M 8K system poised to play a significant role in future aerospace projects and a strengthened partnership with Sintavia, AMCM is preparing for significant advancements in aerospace manufacturing. By incorporating state-of-the-art technology from EOS, the M 8K aims to redefine quality assurance and process monitoring standards.

Martin Bullemer, Managing Director at AMCM, highlighted the challenges and complexities involved in developing a system of this size. Designing the M 8K required expertise in laser, scanner, and optics design, based on decades of experience from EOS. With a build volume four times larger than the M 4K, the system’s z-axis must be capable of moving up to 5 tons of powder with utmost precision. Additionally, the importance of material supply cannot be underestimated, as reliable powder management is crucial for printing tall parts with high productivity and quality.

In conclusion, the unveiling of the AMCM M 8K marks a significant milestone in the additive manufacturing industry. With its partnership with Sintavia and the ability to meet the demands of complex aerospace projects, the M 8K is poised to make waves in the field. As AMCM and its partners continue to push the boundaries of technology and innovation, exciting advancements in aerospace manufacturing lie ahead.

**Embracing Innovation in 3D Printing: The Evolution of Additive Manufacturing**

When it comes to 3D printing, size and process control are essential. The challenge lies in maintaining quality and efficiency throughout the printing process, which is often time-consuming and prone to errors. However, with advancements in technology, the industry is witnessing a revolution in additive manufacturing.

One such innovation is the M 8K system developed by AMCM. This cutting-edge machine promises improved real-time quality checks, thereby reducing the need for later assessments. By integrating the latest EOS technology, SmartFusion, and the monitoring system EOSTATE Exposure OT (optical tomography), the M 8K system ensures that process control is maintained at all times.

According to Bullemer, the M 8K system will be fully operational within a year, with the first printed combustion chambers expected to be ready by 2024. This significant milestone solidifies the system’s vital role in upcoming aerospace projects. The ability to produce high-quality components for critical applications will undoubtedly revolutionize the aerospace industry.

AMCM is not the only player in the race to expand build volumes for industrial applications. Other industry giants like Nikon SLM Solutions, Renishaw, Concept Laser, and TRUMPF have also been pushing the boundaries of additive manufacturing. For example, Nikon SLM Solutions’ NXG XII 600E model boasts an impressive build envelope size, showcasing the industry-wide competition to scale up.

The collaboration between AMCM and Sintavia further demonstrates the vast potential of additive manufacturing. Together, they are navigating the challenges and opportunities presented by metal printing and driving innovation in the industry. This strategic partnership highlights the importance of collaboration and knowledge sharing in unlocking the full potential of additive manufacturing.

In conclusion, the world of 3D printing is experiencing a remarkable evolution. The introduction of the M 8K system and its crucial role in printing the Prometheus combustion chamber signifies a significant milestone. With ongoing advancements and collaborations, additive manufacturing will continue to reshape industries and pave the way for a more efficient and sustainable future.
