M400-4 is biggest and fastest DMLS system from EOS

EOS has introduced its M400-4 DMLS (direct metal laser sintering) machine, which is the biggest and fastest in the company’s portfolio. The machine offers a build volume of 400 by 400 by 400 mm and is equipped with four 400 W lasers operating independently in 250 by 250 mm squares, each overlapping by 50 mm.

As part of the system, patented EOS ClearFlow technology is deployed to ensure the distribution of process gas in an intelligent way, thus avoiding any interference to the lasers. In addition, the integrated industrial grade recirculating filter system, with its long operational life expectancy, reduces operating times and costs.

The system is operated via a touch-screen and a task-based graphical user-interface, while Eostate technology supports monitoring of the powder bed, laser power and a variety of other parameters.

Initially, EOS NickelAlloy HX and EOS MaragingSteel MS1 materials will be made available.
