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 for 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. Out-of-the-box, the AMCM M 4K can produce applications from a range of materials, including aluminum (AlSi10Mg), nickel alloy (IN718), and copper alloy (CuCr1Zr).

Additional details of the AMCM M 4K Platform:

  • Large building volume of 450 x 450 x 1,000 mm
  • Laser Type: Yb Fiber laser: 1 x 1,000 watt, 4 x 400 watt or 4 x 1,000 watt, optional
  • Wave length: 1,070 nm
  • Precision Optics: F-theta-lens
  • Scan Speed during build process: up to 7.0 m/s (23 ft./sec)
  • Process Gas Cooling: additional gas cooling unit (optional)
  • Dimensions of complete system: (W x D x H): 193 x 83 x 122 in
  • Compatible with legacy EOS M 400 Series process parameter sets
  • Powder handling option for manual or semi-automatic operation
  • Open software for process optimization with high power laser

Powder bed DMLS 3D printing is used for the most demanding applications – high performance, sophisticated, mission critical parts. Launcher was one organization that realized early in the AMCM M 4K’s development that it could now produce – using the 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 one 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 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, custom industrial 3D printers based on EOS technology.
