EOS Expands Portfolio with Four New Metal Materials for Industrial 3D Printing Systems

The German manufacturer EOS has introduced four new metal materials for industrial 3D printing. The materials – FeNi36, NickelAlloy C22, Steel 42CrMo4, and StainlessSteel 316L-4404 – have been optimized for the company’s Laser Powder Bed Fusion (LPBF) systems. With this expansion, EOS is responding to increasing demand for additive manufacturing solutions in industries such as aerospace, energy, chemical processing, automotive, and shipbuilding.

EOS FeNi36 is an iron-nickel alloy characterized by exceptionally low thermal expansion. With a coefficient of less than 2 ppm/K between 30 and 150 degrees Celsius, the material is ideal for applications requiring dimensional stability despite temperature fluctuations. Typical use cases include precision components such as optical mounts, measuring instruments, and cryogenic parts. The alloy is compatible with the EOS M 290 system and will be showcased at Formnext 2025 through demonstration parts.

With EOS NickelAlloy C22, the company adds a highly corrosion-resistant nickel alloy suitable for chemical processing and food technology applications. The material combines strength, toughness, and chemical resistance, and is also compatible with the EOS M 290 platform.

EOS Steel 42CrMo4 targets the automotive and mobility sectors. This proven structural steel is now being adapted for additive manufacturing to produce parts such as gears, shafts, and brackets. By optimizing the material for the LPBF process, EOS aims to shorten development times and maximize lightweight design potential.

As the fourth addition, EOS introduces StainlessSteel 316L-4404, a variant of the well-known stainless steel 316L that is tailored to industrial requirements and offers improved cost efficiency.

“With these additions, we are expanding our material portfolio to meet the industry’s most demanding requirements. Whether it’s the unmatched thermal stability of EOS FeNi36, the corrosion resistance of NickelAlloy C22, or the accessibility of widely used steels like 42CrMo4 and 316L-4404, we empower our customers to innovate faster, address supply chain challenges, and bring additive manufacturing to new applications. Our team looks forward to showcasing our entire portfolio of metal materials at Formnext,” said Hanna Pirkkalainen, Head of Product Management at EOS Oy.
