Germany-based GEFERTEC will exhibit a 700 kg WAAM wire-arc additive manufacturing compressor impeller at Formnext 2026 (November 17-20, Frankfurt, Berlin-Brandenburg joint booth, Hall 12.1 B101), one of the largest parts ever displayed made with the WAAM process. Also on show are a titanium alloy aircraft emergency exit frame, molds, and a first-time public reveal of a "fish-friendly" seawater pump impeller whose long airfoil-shaped blades let ingested fish pass through safely, a geometry that cannot be formed by conventional casting. Two new machines will be launched at the same time: the modular arc10X, which integrates into existing production lines and complements the arc80X with its maximum 8 m³ build volume, and the arcTitan dedicated to titanium alloys, combining plasma WAAM with a fully sealed inert atmosphere that keeps oxygen content controlled at 10-15 ppm throughout the process. Value for buyers: large structural components can replace castings and forgings with wire-based WAAM, offering high material utilization and lower overall cost than powder bed processes, making it suitable for energy, marine, and mold applications; the sealed titanium printing solution opens up the aviation structural parts market. GEFERTEC is a wholly owned subsidiary of the Berlin industrial group B.I.G. (around 360 employees) and has announced plans to launch a containerized mobile additive manufacturing system aimed at in-situ, on-site production scenarios.
