EOS acquires Metalpine to boost titanium powder for aerospace AM

EOS has acquired 100% of Metalpine GmbH, moving the Austrian powder maker fully under its umbrella after holding a stake for several years. The deal, announced in mid-April 2026, gives EOS tighter control over a feedstock supplier built around titanium and other high-performance metal powders, while Metalpine keeps its own brand, structure, and day-to-day operations.

The acquisition lands in a part of metal additive manufacturing where reliability matters as much as capacity. EOS said the purchase strengthens its materials strategy, especially in titanium additive manufacturing, and expands access to high-quality titanium powders for aerospace, medical, and other industrial applications. EOS also said the deal is intended to improve process stability, scalability, and industrial readiness, three things that matter when powder consistency can make or break qualification work.

Metalpine’s pitch has always centered on control of the powder itself. The company uses a proprietary wire-based gas atomization process and says it produces highly spherical, pore-free powders. EOS described Metalpine as AS/EN9100 certified and headquartered in Graz, Austria, while EOS remains based in Krailling, Germany. Metalpine was founded in 2015 and had already been linked to EOS since November 2021, when EOS first took a stake to cooperate more closely on innovative and sustainable metal powders.

That longer relationship makes the acquisition look less like a surprise purchase than a deeper lock-in of an existing ecosystem. EOS CTO Joachim Zettler called Metalpine a strong, innovative partner for many years and framed the full acquisition as the next step in that collaboration. Metalpine CEO Gerald Pöllmann described it as a natural progression that should help the company develop its technologies further and scale up while still serving customers worldwide. Metalpine CTO Martin Doppler pointed to the company’s patented process and its powder quality and consistency as the core value EOS is buying into.

For buyers, the tradeoff is familiar across metal AM: tighter integration can mean fewer variables between powder supplier and machine ecosystem, which can help qualification and repeatability. It can also reduce the number of truly independent powder options if more suppliers are pulled inside OEM-owned stacks. EOS is betting that aerospace and other demanding users will prize the former enough to accept the latter, especially as titanium demand keeps pushing the market toward more vertically integrated supply chains.
