Direct Metal Laser Sintering for Industrial Applications

EOS, a global provider of high-end Additive Manufacturing (AM) solutions, has introduced its new system for Direct Metal Laser Sintering (DMLS). "Designed for industrial applications, the ultra-fast quad-laser system expands the EOS DMLS offering by building on established EOS technology, yet taking it to the next level in terms of productivity, part quality and scalability to meet manufacturing requirements," said an EOS spokesperson.

"We chose the EOS M400-4 system to bring our Additive Manufacturing activities to the next level: from a small scale single laser unit to a larger scale multiple laser unit," said Andreas Graichen, Group Manager, Finspang Additive Manufacturing Centre of Competence, Siemens Power Generation Services. "With the higher productivity provided by using a wider building platform paired with a new handling system, new thinking in gas turbine design can be brought into the industrial workshop. The Additive Manufacturing technology provides us with the speed and efficiencies needed to progress in the energy industry's fast-moving digital environment. This innovation makes Siemens a unique player in the field of highly efficient power generation technologies."

"Following our strategy to establish the Additive Manufacturing technology for production in all industries we have developed this pioneering DMLS system," said Dr. Adrian Keppler, Chief Marketing Officer, EOS. "The EOS M 400-4 is a perfect addition to our industrial systems portfolio. It shatters the boundaries of manufacturing as it meets the most demanding requirements of our industry partners in terms of efficiency, scalability, usability and process monitoring. The system offers a modular platform designed for industrial 3-D printing which can easily be integrated into existing production environments."

Building on the Trusted EOS Metal AM Benchmark

The EOS M 400-4 expands the high-performance offerings of DMLS systems. It offers a large building volume of 400 x 400 x 400 mm and is equipped with four 400 Watt lasers operating independently in 250 x 250 mm squares each including an overlap of 50 mm. "The exceptional beam and power stability ensures highest DMLS part quality," said the EOS spokesperson. "The system builds on the well-established and validated process of the EOS M 290 technology. It takes innovation to the next production level as it quadruples productivity. As such it is the perfect choice for those Additive Manufacturing applications that need an up to four time's faster production of metal parts."

New EOS ClearFlow Process Gas Management System

As part of the EOS M 400-4 system, the patented EOS ClearFlow process gas management technology is designed to ensure optimal and consistent processing conditions. It 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 is designed to reduce operating times and expenses.

EOSTATE Monitoring Suite

Usability and workflow on the EOS M 400-4 have been designed to meet demanding production requirements. The intuitive software offers workflow flexibility and efficiency. The system is designed to be easily operated via a touchscreen and a task-based graphical user-interface. The extensive EOSTATE Monitoring Suite ensures compliance with the requirements of industrial production: it enables monitoring of the powder bed, a variety of parameters and the laser power. Data Preparation and calculation is separated from the building process: the file prepared at desk is transmitted via the network. The system focuses entirely on building parts.

Material and Process Portfolio

Initially, the materials EOS NickelAlloy HX as well as EOS MaragingSteel MS1 will be available for the EOS M 400-4 and more materials and processes will follow soon. Parameters can be modified to meet individual application requirements using the EOS ParameterEditor.
