Six K Additive Secures Defense Contract to Recycle Critical Metal Powders

Published on April 22, 2026 | Translated from Spanish

The company 6K Additive has received a $2 million contract from the U.S. Department of Defense. The goal is to localize the production of essential metal powders for additive manufacturing. The 18-month project aims to recover metals like nickel or titanium from scrap and obsolete components within military facilities, reducing dependence on foreign imports.

The UniMelt Process and Strategic Circular Economy 🔄

The core technology of 6K Additive is its UniMelt plasma system. This process allows the conversion of metal waste, from chips to complete components, into high-quality powder suitable for 3D printing. The approach is not just about recycling, but about creating a secure and circular supply chain for critical defense materials, avoiding global market volatility and potential supply disruptions.

From Forgotten Scrap to Strategic Component, Without the Checkout 💰

It seems every soldier's dream has come true: now, that piece from an old tank or a retired aircraft can have a glorious second life, without needing a passport. It's as if the motto reduce, reuse, recycle has been adopted by the Pentagon, albeit with a twist more fitting of a top-secret mission. Instead of relying on overseas shipments, it's enough to rummage through the base's storage room. A circular economy with a patriotic accent.
