Aerospace AM specialist Sintavia will become the first North American user of AMCM’s M 8K 3D printer, one of the largest powder bed fusion printers built to date. Sintavia and AMCM announced the deal at Formnext 2023, stating that delivery of the machine is expected to take place in early 2025.

“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,” said Martin Bullemer, Managing Director of AMCM GmbH. “We look forward to working with the Sintavia team to see how they apply this game-changing technology.”

Designed by EOS Group company AMCM, the M 8 K has a build area of 820mm x 820mm x 1600mm and is equipped with eight nLIGHT AFX-1000 lasers. Its architecture is based on that of the M 4K platform, which was itself based on the architecture of the EOS M400-4 multi-laser printer.

The launch of the giant M 8K took place in September 2023 alongside European aerospace company ArianeGroup, which intends to use the machine to produce the combustion chamber of its Prometheus rocket engine. Meanwhile Sintavia, operating across the Atlantic, plans to use the printer for a mix of applications, including XL parts and efficient batch printing of smaller components.

“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.”

The addition of the huge metal 3D printer will add further capabilities to Sintavia’s existing fleet of AM systems, which currently includes seventeen AMCM and EOS GmbH printers, including two M 4K printers it acquired in 2021.
