Additive Manufacturing Customized Machines (AMCM), an EOS Group company in Germany, announces the serial production of its AMCM M 4K-1 (single laser) and AMCM M 4K-4 (four laser) industrial Direct Metal Laser Sintering metal 3D printing platforms. Built on the industry proven EOS M 400 platform, the AMCM M 4K is tailored to produce large parts with a height up to one meter (39.37 inches).
Additional features include increased robustness of the frame design, a new filter system, and optional soft recoating. Out of the box, the AMCM M 4K can produce parts from a wide range of materials, including alloys of aluminum, nickel, and copper.
Dimensions of the complete system are (W x D x H): 193 x 83 x 122 inches, with a building volume of 17.7 x 17.7 x 39.37 inches. Its ytterbium fiber laser is available with 1 x 1000 watts, 4 x 400 watts, or 4 x 1000 watts, optional. Scan speed during build process is up to 7.0 m/s (23 ft./sec).
Launcher Inc., New York, used the AMCM M 4K to produce its copper alloy E-2 combustion chamber, the world’s largest 3D-printed liquid rocket engine. According to Launcher CEO Max Haot, “The AMCM M 4K solved both our goal to 3D print a tall combustion chamber in a single piece, and to produce it in a copper material. Printing in a single piece reduces cost and enables the highest-performance regenerative cooling design.”
