AMCM M 4K
Large scale, high productivity system for demanding AM applications. 1 meter building height with up to 4 x 1,000 W laser power.
Starnberg, Bavaria, Germany – May 28, 2020
Based on the EOS M 400 series, the customized, high-performance Direct Metal Laser Solidification (DMLS®) printers now in production at AMCM’s newly expanded facility.
New 3D printer available in both one (1) and four (4) laser offerings
Available build volume of 450 x 450 x 1000mm
Rocket manufacturing organizations seen as early adopters
Several M 4K currently in production in the dedicated new production facility in Starnberg
Built on the industry proven EOS M 400 platform, the AMCM M 4K is tailored to produce large applications, with a height up to one meter (39.37 inches). Additional features include increased robustness of the frame design, a new filter system (RFS 2.0), and optional soft recoating. The AMCM M 4K can produce applications from a wide range of materials, including aluminum (AlSi10Mg), nickel alloy (IN718), and copper alloy (CuCr1Zr).
The AMCM M 4K is a wholly new offering that we have been perfecting for two years. What customers can appreciate is that its underpinnings are that of the EOS M 400 processes— which are the benchmark for metal 3D printing,” said Martin Bullemer, managing director of AMCM. “Our team is extremely proud of this system now producing the biggest, highest quality metal powder- bed 3D printing applications in the world.

Powder bed DMLS 3D printing is used for the most demanding applications – high performance, sophisticated, mission critical parts. With the help of AMCM, Launcher was one such organization that realized very early in the AMCM M 4K’s development that it could now produce – using the preferred DMLS method – its copper alloy E-2 combustion chamber, the world’s largest 3D printed liquid rocket engine. “The AMCM M 4K solved for both our desire to 3D print a tall combustion chamber in a single piece, and produce it in a copper material,” said Launcher CEO, Max Haot. “Printing in a single piece reduces cost and enables the highest-performance regenerative cooling design.” Launcher will be testing E-2 at NASA Stennis as part of an Air Force Phase II SBIR later this year.
The AMCM M 4K platform is a global offering and is available now. AMCM is ramping up its production at their new expanded facility in Starnberg, Germany. In addition to the AMCM M 4K platform, AMCM is pushing the limits of additive manufacturing (AM) technology producing other high-performance, customized industrial 3D printers based on EOS technology.
