New Materials for EOS Printers
May 16, 2019Comments
EOS of North America, Inc. has debuted four metal materials for additive manufacturing (AM) along with comprehensive material properties. The materials: EOS StainlessSteel CX, EOS Aluminium AlF357, EOS Titanium Ti64 Grade 5 and EOS Titanium Ti64 Grade 23. They have been tailored to suit an array of applications, ranging from automotive to medical.
The company offers comprehensive data for all four metals, including the number of test specimens on which the mechanical properties are based, as well as detailed scanning-electron-microscope images that provide insight into material quality. This provides companies with documentation and transparency that make it easier for them to compare direct metal laser sintering (DMLS) 3D printing with traditional manufacturing and other 3D printing technologies, according to EOS officials, who note that such data and openness are requirements for the use of AM in series production.
EOS StainlessSteel CX, a new tooling-grade steel developed for production with the EOS M 290 machine, combines corrosion resistance with high strength and hardness. Components made from this material reportedly are simple to machine and provide an excellent polished finish.
EOS Aluminum AlF357, ideal for applications requiring a light metal with mechanical/thermal strength, deliver components characterized by light weight, corrosion resistance and high dynamic loading. This material has been developed for production with the EOS M 400, but EOS plans to make it available for the EOS M 290 system in the near future.
