Additive Manufacturing Customized Machines (AMCM), an EOS Group company based in Starnberg, Germany, has launched its AMCM M 4K-1 (single laser) and AMCM M 4K-4 (four laser) industrial Laser Beam Powder Bed Fusion (LB-PBF) metal Additive Manufacturing machines.
Built on the proven EOS M 400 platform, the AMCM M 4K is designed for the production of large components, with a build height of up to 1 m. 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 parts from a wide range of materials, including aluminium (AlSi10Mg), nickel alloy (IN718) and copper alloy (CuCr1Zr).
Martin Bullemer, Managing Director of AMCM, stated, “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. Our team is extremely proud of this system now producing the biggest, highest quality metal powder bed 3D printing applications in the world.”
Mission critical applications: Launcher combustion chamber
LB-PBF Additive Manufacturing is used for some of the most demanding applications – including high-performance and mission critical parts. Rocket developer Launcher was one of the AMCM M 4K’s earliest adopters, using the technology to produce its copper alloy E-2 combustion chamber, a very large additively manufactured 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,” explained Max Haot, Launcher CEO. “Printing in a single piece reduces cost and enables the highest-performance regenerative cooling design.”
Launcher will be testing the 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, and several machines are currently in production at the company’s dedicated new production facility in Starnberg. In addition to the AMCM M 4K platform, the company reports that it is producing further high-performance, customised industrial AM machines based on EOS technology.
