EOS introduces the EOS M 400-4, a quad-laser direct metal laser sintering (DMLS) system designed for industrial applications. The machine offers a modular platform that EOS says can be easily integrated into existing production environments.

Building on the process of the EOS M 290, the EOS M 400-4 offers a build volume of 400 × 400 × 400 mm and is equipped with four 400-W lasers operating independently in 250 × 250-mm squares each including an overlap of 50 mm. The independent lasers make it possible to quadruple productivity, and good beam and power stability ensures high DMLS part quality, the company says.

The system is equipped with EOS ClearFlow process gas management technology to ensure optimal and consistent processing conditions. According to EOS, this technology distributes the process gas in an intelligent way to avoid interference of the lasers with side products of the melting process. In addition, the integrated industrial-grade, recirculating filter system with its long filter lifetime significantly reduces operating times and expenses.

A touchscreen and task-based graphical user interface simplifies operation. EOState monitoring suite enables monitoring of the powder bed, including laser power and other parameters. Data preparation and calculation is separated from the build process. The file is prepared on a desktop and then transmitted to the machine via the network, so that the machine is entirely focused on building parts.

EOS NickelAlloy HX and MaragingSteel MS1 are currently available for the EOS M 400-4, with more materials to follow.
