Industrial 3D printer maker EOS introduces today two new metal materials: EOS Titanium Ti64ELI and EOS StainlessSteel 316L.
EOS Titanium Ti64ELI: light metal alloy – corrosion resistant and biocompatible
Titanium Ti64ELI is a pre-alloyed Ti6AlV4 alloy in fine powder form. ELI stands for "extra low interstitial". Essentially, this is a controlled chemistry version of standard Ti6AlV4 with lower oxygen content. This well-known light alloy is characterized by having excellent mechanical properties and corrosion resistance combined with low specific weight and biocompatibility.
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, according to EOS. This material is ideal for the production of biomedical implants and can be used in aerospace and motor racing.
Parts built from EOS Titanium Ti64ELI can be machined, spark-eroded, welded, micro shot-peened, polished and coated. Unexposed powder can be reused.

EOS Stainless Steel 316L: corrosion resistant and biocompatible stainless steel
This stainless-steel alloy 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 can also be used to make watch cases, spectacle frames or functional elements in yachts, and clamping elements or heat exchangers in the aerospace industry.
Parts manufactured from that material can be mechanically post-processed or polished.

I sure hope EOS is GE Aviation's printer of choice for the Leap fuel nozzles, as I am betting on Sigma Labs to be the QA piece in the puzzle. There are many connections between GE, EOS and Sigma Labs.

Is EOS going to provide GE Aviation with the industrial 3D printers they will need to produce their new fuel nozzle in their Auburn, AL plant?

Where is the low-cost 3D metal printer that we have all been waiting for? Do you think the maker community would take on the challenge?
