EOS has launched 4 new steel additive manufacturing supplies to its portfolio forward of the Formnext commerce truthful in Frankfurt subsequent month.
The EOS FeNi36, EOS NickelAlloy C22, EOS Metal 42CrMo4, and EOS StainlessSteel 316L-4404 supplies have every been optimised for EOS Laser Powder Mattress Fusion (LPBF) programs.
In response to EOS, they are going to additional broaden the corporate’s skill to ‘deal with specialised AM necessities throughout the aerospace, vitality, chemical, automotive, and marine industries.’
EOS FeNi36 has been designed to be appropriate for purposes the place precision and stability beneath fluctuating temperatures are important, with EOS concentrating on the aerospace, house, defence, and vitality sectors. It’s mentioned to have an exceptionally low coefficient of thermal enlargement (<2 ppm/Okay between 30–150°C), whereas offering as much as 10x decrease thermal enlargement than alloys like 316L and MS1. Suitable with the EOS M 290 system, EOS says typical purposes embody optical housings, mirror mounts, cryogenic instrument elements, optical benches, precision metrology inserts, and small composite tooling inserts. At Formnext, the corporate will current a lobed jet engine nozzle and optical housing, each manufactured within the materials.
The EOS NickelAlloy C22 displays corrosion resistance, excessive energy, and toughness properties, with EOS suggesting it appropriate for industries the place contact with organic and chemical media is unavoidable. Initially suitable with the EOS M 290 collection, the corporate will goal the chemical processing and meals processing markets with this product.
With the EOS Metal 42CrMo4, in the meantime, EOS is concentrating on the automotive house. A extensively used materials within the sector, EOS has optimised the fabric for additive manufacturing, providing its excessive toughness and energy properties for customers of 3D printing. Additionally suitable with the EOS M 290 collection, EOS suggests the fabric is good for the engineering of elements, gears and shafts.
Lastly, the EOS StainlessSteel 316L-4404 is a European industry-standard stainless-steel variant that mixes excessive ductility, toughness, energy, and corrosion resistance. Tailor-made for industries similar to chemical processing, meals manufacturing, water dealing with, and marine, the alloy delivers confirmed efficiency at a decrease price. The brand new chemistry variant is extra industrial grade than customary EOS 316L, whereas sustaining compatibility with present StainlessSteel 316L parameter units. The fabric is suitable with a variety of programs, together with EOS M 290, EOS M 400, EOS M 400-4, and EOS M 300-4.
“With these additions, we proceed to broaden our supplies portfolio to satisfy probably the most demanding {industry} necessities,” mentioned Hanna Pirkkalainen, Head of Product, EOS Oy. “Whether or not it’s the unmatched thermal stability of EOS FeNi36, the corrosion resistance of NickelAlloy C22, or the accessibility of extensively used steels like 42CrMo4 and 316L-4404, we’re enabling our prospects to innovate quicker, deal with provide chain challenges, and convey additive manufacturing into new purposes. Our group is worked up to debate our whole steel supplies portfolio at Formnext.”
