EOS Strengthens Steel 3D Printing Portfolio with 4 New Powders – 3DPrint.com

Industrial 3D printing firm EOS not too long ago started a partnership with Sauber Applied sciences for its polymer 3D printing, however is unquestionably working to proceed enhancing its metallic 3D printing capabilities as nicely. Right now, the corporate introduced that its metallic 3D printing supplies portfolio for the M 290 printer has grown with the addition of 4 new supplies. The mid-sized, highly effective DMLS system already has fairly an intensive supplies portfolio, and the addition of those new stainless-steel, instrument metal, and nickel alloy supplies will simply make it stronger.

EOS has what it calls the High quality Triangle, which is a singular strategy in our trade. The corporate takes the information from every of the three essential technical components of the AM manufacturing course of—the system, the fabric, and the method—and assigns every mixture a Know-how Readiness Stage (TRL). This designation makes the estimated manufacturing functionality and efficiency of the options extra clear, so prospects know simply what they’re getting. Premium merchandise (TRL 7-9) have a confirmed functionality, extremely validated course of knowledge, and reproducible half properties. TRL 3 and 5 are known as core merchandise, which implies that they’re much less mature and with much less knowledge, however give prospects early entry to know-how that’s nonetheless below improvement. These 4 new supplies have all obtained a TRL 3 Core classification.

The primary of those new supplies is EOS StainlessSteel 254, well-suited for purposes in excessive situations, comparable to chemical dealing with tools, pulp and paper manufacturing units, and chlorinated seawater dealing with tools. The austenitic stainless-steel options excessive resistance to pitting, uniform, and crevice corrosion, and comes with a 40/60 µm course of for the EOS M 290 printer. This materials’s wonderful corrosion resistance comes from its excessive chromium, molybdenum and nitrogen alloying, and EOS says it additionally options nice stress corrosion cracking, in addition to increased power than standard austenitic metal.

The opposite stainless-steel materials is EOS StainlessSteel SuperDuplex, for tough environments. Optimized for AM, the austenitic-ferritic duplex stainless-steel maintains “tremendous duplex properties,” and in addition options excessive chromium, molybdenum and nitrogen alloying for nice corrosion resistance.

Similar to EOS’s different new stainless-steel, StainlessSteel SuperDuplex exhibits nice pitting, uniform, and crevice corrosion resistance. The corporate says this materials additionally permits excessive power, and that it’s nice for purposes in mining and offshore tools, the oil and fuel trade, and for pulp and paper manufacturing units. It comes with a 40/80 µm course of for the M 290, and resulting from what EOS calls the “optimization of section steadiness,” this materials can typically be utilized in as-manufactured situation.

“Materials improvement is all the time 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,” defined Sascha Rudolph, SVP BU Steel Supplies at EOS. “We’re rising software alternatives for demanding industries by bringing AM tailor-made alloys to our prospects.”

The brand new cobalt-free, ultra-high power EOS ToolSteel CM55 is supposed to be used at elevated temperatures in tooling and engineering options. This excessive hardness metal has a 40/80 µm course of for the EOS M 290 printer, and the mixture of its reasonable carbon content material and alloying components have fashioned a steady, sturdy construction for extra demanding purposes, comparable to powertrain parts, hot and cold working instruments, and components for mechanical engineering.

Lastly, the final new materials, EOS NickelAlloy HAYNES 282, can be meant for 3D printing components for purposes at elevated temperatures. Manufactured below license from Haynes Worldwide Inc., this precipitation strengthened, nickel-based superalloy powder was developed particularly for high-temperature structural purposes, comparable to vitality trade parts, turbomachinery and fuel turbine components, and aerospace and rocket engine parts. It options what EOS calls a “distinctive mixture” of thermal stability, wonderful weldability, good oxidation and corrosion resistance, and excessive temperature power.
