Krailling/Munich, Germany, July 14, 2022 – EOS, a leading supplier for responsible manufacturing solutions via industrial 3D printing technology, has today announced the introduction of four new metal materials for additive manufacturing (AM) on the EOS M 290 metal system, including two stainless steels, one tool steel and one nickel alloy.
Material development is always driven by customer demand and very often is the result of a close customer cooperation. These four new metal materials were designed and optimized specifically to the needs of additive manufacturing. We are increasing application opportunities for demanding industries by bringing AM tailored alloys to our customers.
The EOS StainlessSteel SuperDuplex comes with a 40/80 µm process for the EOS M 290 system. This is an austenitic-ferritic duplex stainless steel optimized for additive manufacturing while maintaining super duplex properties.
Its high chromium, molybdenum and nitrogen alloying give excellent corrosion resistance in many difficult environments.
At the same time, it shows excellent resistance to uniform, pitting and crevice corrosion, as well as enabling high strength together with high corrosion resistance.
The optimization of phase balance enables use of the product in as manufactured condition in many use cases. The material is particularly suited for applications in the oil and gas industry, in pulp and paper manufacturing devices and for mining and offshore equipment.
EOS NickelAlloy HAYNES® 282® is a nickel alloy powder intended for manufacturing parts on EOS metal systems.
It is a precipitation strengthened nickel-base superalloy with a unique combination of high temperature strength, thermal stability, good corrosion, and oxidation resistance, easy fabricability and excellent weldability.
It was developed for high temperature structural applications and is manufactured under license from Haynes International Inc.
Typical applications range from aerospace and rocket engine components to turbomachinery and gas turbine parts, and to energy industry components.
EOS uses an approach that is unique in the AM industry, taking each of the three central technical elements of the production process into account: the system, the material, and the process. The data resulting from each combination is assigned a Technology Readiness Level (TRL) which makes the expected performance and production capability of the solution transparent. EOS incorporates these TRLs into two categories: premium products (TRL 7-9) offer highly validated data, proven capability, and reproducible part properties. Core products (TRL 3 and 5) enable early customer access to newest technology still under development and are therefore less mature with less data. All of the above materials have a TRL 3 Core classification.
EOS provides responsible manufacturing solutions via industrial 3D printing technology to manufacturers around the world. Connecting high quality production efficiency with its pioneering innovation and sustainable practices, the independent company formed in 1989 will shape the future of manufacturing. Powered by its platform-driven digital value network of machines and a holistic portfolio of services, materials and processes, EOS is deeply committed to fulfilling its customers’ needs and acting responsibly for our planet.
