German Additive Manufacturing systems provider EOS has expanded its range of materials for metal AM applications to include Titanium Ti64ELI and Stainless Steel 316L. The two new grades of powder will complement the company’s existing range of material suitable for the production of metal components using the DLMS (Direct Metal Laser Sintering) process.
EOS offers a comprehensive selection of metal powders ranging from aluminium, maraging steel and high-grade steel through to titanium as well as nickel and cobalt chrome alloys.
“A broader variety of titanium and stainless steel materials mirrors the ever changing requirements among our customers and opens up new fields of application,” stated Christiane Krempl, Product Marketing Manager Metals at EOS.
Parts built in EOS Titanium Ti64 have a chemical composition and mechanical properties corresponding to ASTM F136. Providing a high detail resolution it can be processed on an EOSINT M 280 (400 Watt) metal laser-sintering system. This light metal alloy 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, the company stated.
This EOS Stainless Steel 316L alloy has been optimised specifically for the processing on the EOSINT M 280 metal laser-sintering system. It shows a good corrosion resistance and a high ductility. Parts built from EOS Stainless Steel 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, for endoscopic surgery, orthopaedics and implants. The material is also a good choice for use in the watch and jewellery industry, where the designer benefits from extensive freedom of design. Parts such as watch cases thanks to defined hollow spaces can be manufactured more cost-efficiently and easily, at the same time 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 Stainless Steel is a good choice for the manufacture of clamping elements or heat exchangers. Parts manufactured from that material can mechanically post-processed or polished.
