The German 3D printer vendo Electro Optical Systems, better known as EOS, has announced four new metal materials, aimed at a broad array of applications, ranging from automotive to medical applications.
Amongst these new materials, StainlessSteel CX is a new tooling grade steel developed for production with the EOS M 290. It’s said to offer good corrosion resistance with high strength and hardness. Eos says that components made from this material should be easy to machine with a polished finish.
Aluminum AlF357 is a a light metal said to have good mechanical and thermal strength, as well as corrosion resistance and high dynamic loading. It has been specially developed for production with the EOS M 400 but will also be available for the EOS M 290 system in the near future.
Titanium Ti64 Grade 5 has been specially developed for its high fatigue strength without hot isostatic pressing as well as good corrosion resistance. It’s suitable for use with the EOS M 290, and is mainly aimed at aerospace and automotive applications.
Titanium Ti64 Grade 23 has also been developed for its high fatigue strength without hot isostatic pressing and for production with the EOS M 290. This grade of Ti64 offers improved elongation and fracture toughness with slightly lower strength and is said to be particularly well suited to medical applications.
EOS also offers manufacturers comprehensive data on the material properties of all four metals, such as the number of test specimens on which the mechanical properties are based on. This also includes detailed scanning electron microscope (SEM) images to give users an idea of the qualities of the material. This information should make it easier for customers to compare DMLS 3D printing against both traditional manufacturing technologies and other 3D printing technologies.
Hannes Gostner, director of Research and Development at EOS, says: “At EOS, the development of systems, materials, process parameters, software, and services have always gone hand in hand. All of the elements are perfectly aligned to each other. The result is reproducible high-quality parts at a competitive cost per part. This combination is of crucial importance, particularly for series manufacturing.”
