EOS adds new 3D materials

EOS, which has developed a wide portfolio of industrial 3D printers, has introduced four new metal materials for additive manufacturing for its M290 metal printers.

This Aerospike nozzle design concept was printed with the new EOS NickelAlloy Haynes 282 material.

These materials include two stainless steels, one tool steel and one nickel alloy.  This last, NickelAllow Haynes 282 is a nickel alloy powder, more specifically, a precipitation-strengthened nickel-base superalloy. It was developed for high temperature structural applications and is manufactured under license from Haynes International Inc. It’s said to offer high temperature strength, thermal stability, good corrosion, and oxidation resistance as well as easy fabricability and good weldability. Typical applications range from aerospace and rocket engine components to turbo-machinery and gas turbine parts, as well as for energy industry components.

Then there’s ToolSteel CM55, which comes with a 40/80 µm process for the M290 system. It is a cobalt-free steel that’s said to offer ultra-high strength and high hardness, suitable for tooling and engineering solutions. Its alloying elements and moderate carbon content form a strong and stable structure for demanding applications and for the use in elevated temperatures. Typical applications are cold and hot working tools, powertrain components and parts for mechanical engineering.

For difficult environments, there’s StainlessSteel SuperDuplex, which also offers a 40/80 µm process for the M290. This is an austenitic-ferritic duplex stainless steel optimized for additive manufacturing while maintaining super duplex properties. It features high chromium, molybdenum and nitrogen alloying that should give good corrosion resistance, making it suitable for use in difficult environments. It has good resistance to uniform, pitting and crevice corrosion, as well as enabling high strength together with high corrosion resistance. EOS says that the optimization of phase balance enables use of parts in an ‘as manufactured’ condition in many use cases. The material is particularly suited for applications in the oil and gas industry, in pulp and paper manufacturing devices and for mining and offshore equipment.

Finally, for extreme conditions, there’s StainlessSteel 254, an austenitic stainless steel that comes with a 40/60 µm process for the M290. It features high chromium, molybdenum and nitrogen alloying, which should give good corrosion resistance in difficult environments. It performs well in stress corrosion cracking tests and promises higher strength than conventional austenitic steel. It also shows good resistance to uniform, pitting and crevice corrosion. The material is particularly suited for applications such as chlorinated seawater handling equipment, pulp, and paper manufacturing devices as well as chemical handling equipment.

Sascha Rudolph, SVP BU Metal Materials at EOS, commented: “Material development is always driven by customer demand and very often is the result of a close customer cooperation. These four new metal materials were designed and optimized specifically to the needs of additive manufacturing. We are increasing application opportunities for demanding industries by bringing AM tailored alloys to our customers.”

All of these materials have been designed for use with the EOS M290 metal printer. This uses a 400 watt YB Fiber laser and has a build area of 250 x 250 x 325mm. There’s already a broad range of metals available for use with it, including stainless steel, aluminium, cobalt chrome, NickelAlloy, titanium and Copper.
