Sintavia, LLC, based in Hollywood, Florida, USA, has signed a letter of intent with AMCM GmbH, Starnberg, Germany, to become the North American launch customer of the company’s M 8K Additive Manufacturing machine with an extended Z direction. The M 8K is one of the largest Laser Beam Powder Bed Fusion (PBF-LB) AM machines available to-date, with a build volume of 820 x 820 x 1600 mm.

“Whoever says that there are no economies of scale in AM hasn’t been running a large enough printer,” said Brian Neff, Sintavia’s Founder and CEO. “With over one cubic meter of displacement and eight next generation nLIGHT lasers, Sintavia’s new M 8K will not only allow for very large, complex components to be designed and printed, but also dramatically reduce unit pricing on smaller units. In our experience, there is an exponential increase in product design utility when build chamber dimensions increase linearly, and the M 8K has the largest build chamber of all.”
Martin Bullemer, Managing Director of AMCM, added, “Over the past six years, it has been a pleasure to work together with Brian and his team as we have collectively pushed the envelope for larger and faster machines across the Aerospace & Defense industry. It is a natural fit that the first M 8K in North America — and the first one anywhere with an extended Z-axis — would go to Sintavia. We look forward to working with the Sintavia team to see how they apply this game-changing technology.”
Sintavia currently operates a fleet of seventeen AMCM and EOS Additive Manufacturing machines, including two M 4K machines it acquired in 2021. The M 8K architecture is based on the M 4K platform, which in turn was based on the architecture of the highly successful EOS M400-4 multi-laser AM machine.
AMCM officially launched the M 8K in September 2023 with ArianeGroup as the European launch customer. ArianeGroup, a joint venture between Airbus and Safran, will use the first M 8K, when it arrives in early 2025, to additively manufacture a large combustion chamber for its Prometheus rocket engine. It is expected that Sintavia’s M 8K will run a nickel alloy, with delivery also expected to occur in early 2025.
AMCM is currently exhibiting at Formnext 2023 in Hall 11.1, D49.
