Fortius Metals develops next-generation wire alloys purpose-built for large-format directed energy deposition (DED) and robotic welding. Founded in 2021 and based in Lafayette, Colorado, the company addresses a gap in the metal AM supply chain: wire materials that deliver superior mechanical properties for demanding structural applications, where conventional welding wire or powder-based processes fall short.
The company's core technology is reactive additive manufacturing, a proprietary approach that produces high-performance metal wire alloys. These materials are designed for wire-arc DED systems, enabling fabrication of components that are both stronger and lighter than those made with standard alloys. Fortius holds patents covering its alloy compositions and the reactive manufacturing process.
Fortius sells directly to aerospace primes, defense contractors, and government agencies including the U.S. Army, Navy, Air Force, and NASA, as well as commercial space companies. Applications include structural brackets, rocket engine components, and repair of high-value metal parts. The company has raised $10.4 million from investors including AM Ventures, 412 Venture Fund, M7 Holdings, and Finindus (backed by ArcelorMittal). A key partnership with Elementum 3D links wire development with powder-based AM expertise.
The company's primary differentiator is its materials science and process control for wire-based AM, a segment less crowded than powder bed fusion. However, the small team (1-10 employees) and reliance on a single process type (DED-arc) present scaling risk. Fortius must also compete against established welding wire suppliers and emerging metal AM wire producers to maintain its foothold in aerospace and defense procurement.
