New metallic AM supplies from EOS

EOS, a number one provider of business 3D printing expertise, has launched 4 new metallic supplies for additive manufacturing on the EOS M 290 metallic system, together with EOS StainlessSteel 254, EOS StainlessSteel SuperDuplex, EOS ToolSteel CM55, EOS NickelAlloy HAYNES 282.

“Materials improvement is at all times pushed by buyer demand and fairly often is the results of a detailed buyer cooperation. These 4 new metallic supplies had been designed and optimized particularly to the wants of additive manufacturing. We’re rising utility alternatives for demanding industries by bringing AM-tailored alloys to our prospects,” mentioned Sascha Rudolph, SVP BU Steel Supplies at EOS.

EOS StainlessSteel 254 is an austenitic stainless-steel that comes with a 40/60 µm course of. The fabric has a superb stress corrosion cracking, and better power than typical austenitic metal. The fabric is especially fitted to functions reminiscent of chlorinated seawater dealing with tools, pulp, and paper manufacturing gadgets, in addition to chemical dealing with tools.

The EOS StainlessSteel SuperDuplex comes with a 40/80 µm course of. That is an austenitic-ferritic duplex stainless-steel optimized for additive manufacturing whereas sustaining tremendous duplex properties.  enabling excessive power along with excessive corrosion resistance. The optimization of section stability allows the usage of the printed half in ‘as manufactured’ situation, in lots of use instances. This materials is especially fitted to functions within the oil and fuel business, in pulp and paper manufacturing gadgets, mining, and offshore tools.

Each the EOS StainlessSteel 254’s and the EOS StainlessSteel SuperDuplex’s excessive chromium, molybdenum, and nitrogen alloying give notable corrosion resistance, to each supplies, in lots of troublesome environments. These new metallic AM supplies additionally present nice resistance to uniform, pitting, and crevice corrosion.

EOS ToolSteel CM55 comes with a 40/80 µm course of. It’s a cobalt-free, ultra-high power, and excessive hardness metal for tooling and engineering options. Its alloying components and reasonable carbon content material kind a robust and secure construction for demanding functions and use in elevated temperatures. Typical functions are hot and cold working instruments, powertrain parts, and elements for mechanical engineering.

EOS NickelAlloy HAYNES 282 is a nickel alloy powder meant for manufacturing elements on EOS metallic techniques. It’s a precipitation-strengthened nickel-base superalloy with a singular mixture of high-temperature power, thermal stability, good corrosion, oxidation resistance, simple fabricability, and wonderful weldability. It was developed for high-temperature structural functions and is manufactured underneath license from Haynes Worldwide Inc. Typical functions vary from aerospace and rocket engine parts to turbomachinery and fuel turbine elements, to power business parts.

The EOS High quality Triangle is a singular strategy within the AM business, taking every of the three central technical components of the manufacturing course of under consideration – the system, the fabric, and the method. The information ensuing from every mixture is assigned a Know-how Readiness Stage (TRL) which makes the anticipated efficiency and manufacturing functionality of the answer clear.

EOS incorporates these TRLs into two classes – premium merchandise (TRL 7-9), providing extremely validated knowledge, confirmed functionality, and reproducible half properties, and core merchandise (TRL 3 and 5), enabling early buyer entry to the latest expertise nonetheless underneath improvement, and subsequently much less mature, with much less knowledge. The entire new metallic AM supplies talked about above have a TRL 3 Core classification.
