EOS developed four new additive manufacturing metal materials tailored to suit a broaden array of applications, ranging from automotive to the medical sector. The company also offers 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, as well as detailed scanning electron microscope (SEM) images that provide an insight into the material quality.
Thus, EOS is providing companies with documentation and transparency for production, making it easier for to compare DMLS 3D printing with traditional manufacturing technologies and other 3D printing technologies. Such data and openness are a requirement for the use of additive manufacturing (AM) in series production. The four new materials are EOS StainlessSteel CX, EOS Aluminium AlF357, EOS Titanium Ti64 Grade 5, and EOS Titanium Ti64 Grade 23.
In detail, EOS StainlessSteel CX is a new tooling grade steel developed for production with the EOS M 290 that combines excellent corrosion resistance with high strength and hardness. Components made from this material are easy to machine and enable an excellent polished finish.
EOS Aluminum AlF357 is the ideal material for applications that require a light metal with excellent mechanical/thermal strength. Components made from this material are characterized by their light weight, corrosion resistance and high dynamic loading. The materials has been specially developed for production with the EOS M 400, but it is planned to also make the material available for the EOS M 290 system in the near future.
EOS Titanium Ti64 Grade 5 has been specially developed for its high fatigue strength without hot isostatic pressing (HIP). Suitable for production with the EOS M 290, the material also offers excellent corrosion resistance, making it ideal for aerospace and automotive applications.
EOS Titanium Ti64 Grade 23 has also been specially developed for its high fatigue strength without hot isostatic pressing (HIP) and for production with the EOS M 290. Compared to Ti64, Ti64 Grade 23 offers improved elongation and fracture toughness with slightly lower strength. Thanks to these properties, it is particularly well suited to medical applications.
