AMCM M 4K-1/4K-4 3D Printer

AMCM, an EOS Group company, announced the serial production of its AMCM M 4K-1 (single laser) and AMCM M 4K-4 (four laser) industrial DMLS metal 3D printing platforms.

Built on the EOS M 400 platform, the AMCM M 4K is tailored to produce large applications, with a height up to one meter (39.37 in.). Additional features include a robust frame design, a filter system (RFS 2.0), and optional soft recoating. Out-of-the-box, the AMCM M 4K can produce applications from a wide range of materials, including aluminum, nickel alloy, and copper alloy.

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.
