Continuous Composites wins contract to advance CF3D technology for missile manufacturing supporting U.S. defense programs

Continuous Composites, a Coeur d'Alene, Idaho-based developer of continuous fiber 3D printing technology, has secured a contract to advance its CF3D process for missile manufacturing applications under U.S. defense programs. The award, announced via CompositesWorld, extends the company's work with the Department of Defense to qualify its in-situ consolidated, continuous carbon fiber-reinforced thermoset composite additive manufacturing process for production of missile structures and components. Specific contract value, duration, and program office details were not disclosed, but the work targets moving CF3D from demonstration readiness toward production-representative environments for defense platforms.

This contract lands at a moment when the U.S. defense industrial base is actively seeking additive manufacturing solutions that can reduce lead times and supply chain dependencies for missile and munitions production. Continuous Composites' CF3D process competes in the large-format, continuous fiber AM space against technologies from companies like Orbital Composites, 9T Labs, and Markforged (on the continuous fiber front), but CF3D's key differentiator is its use of thermoset resins with in-situ curing, enabling high fiber volume fractions and mechanical properties closer to traditional prepreg layup than typical fused filament approaches. The defense vertical has become a politically accelerated adoption segment in 2025-2026, driven by NDAA provisions and munitions replenishment priorities, making this contract a meaningful step toward embedding CF3D into qualification pipelines that could lead to production programs rather than one-off prototypes.

For Continuous Composites, the practical challenge now is moving from contract win to repeatable, qualified production output. Defense programs demand documented process control, material traceability, and mechanical property allowables - not just impressive demo parts. The company must demonstrate that CF3D can hold dimensional and mechanical consistency across multiple builds and machines, and that its thermoset material system can survive the environmental and handling requirements of missile applications. If it delivers on those fronts, this contract could become a reference case that opens adjacent defense and aerospace programs. If not, it remains another development award in a long line of defense AM experiments.
