EOS of North America, Novi, Mich., expands its metal materials portfolio with EOS Titanium Ti64ELI and EOS StainlessSteel 316L. The goal is to offer a broader range of titanium and stainless steel materials and open up new fields of application for components fabricated by laser sintering of powder metals. Ti64ELI provides high-detail resolution. StainlessSteel 316L provides high ductility for medical applications such as surgical instruments and orthopedics.
Parts built in EOS Titanium Ti64 have a chemical composition and mechanical properties corresponding to ASTM F136. Providing a high-detail resolution, this alloy can be processed on an EOSINT M 280 (400 Watt) metal laser-sintering system and shows an excellent corrosion resistance. Due to its biocompatibility and high grade of purity it is particularly suited for the additive manufacturing of medical implants.
EOS StainlessSteel 316L has been optimized specifically for processing on the EOSINT M 280 metal laser-sintering system. It shows a good corrosion resistance and a high ductility. Parts built from EOS StainlessSteel 316L have a chemical composition corresponding to ASTM F138 (“Standard Specification for Wrought 18Cr-14Ni-2.5Mo Stainless Steel Bar and Wire for Surgical Implants UNS S31673”). In the medical industry, this alloy is particularly suited for surgical instruments, endoscopic surgery, orthopedics and implants.
The material is also a good choice for use in the watch and jewelry industries, where the designer benefits from extensive freedom of design. Shaping and structural restrictions as such are a thing of the past. Parts such as watch cases (thanks to defined hollow spaces) can be manufactured more cost-efficiently and easily, saving resources. The material is also well suited for additive manufacturing applications such as spectacle frames or functional elements in yachts. In the aerospace industry, EOS StainlessSteel is a good choice for the manufacture of clamping elements or heat exchangers. Parts manufactured from that material can be mechanically post-processed or polished.
