DED-Arc (Wire Arc) (DED-Arc) is Wire Arc Additive Manufacturing (WAAM) - metal wire is fed into an arc, creating large parts at high deposition rates with lower resolution but strong economics at scale. AMPulse tracks 50 companies using DED-Arc (Wire Arc) as a core technology, ranked below by total funding raised.
Typical materials: stainless steel, titanium, aluminum, nickel alloys, bronze. Common applications: ship propellers, large aerospace structures, construction steel, defense platforms.
DED-Arc, also known as Wire Arc Additive Manufacturing (WAAM), uses an electric arc (derived directly from gas-metal-arc welding (GMAW), gas-tungsten-arc welding (GTAW), or plasma-arc welding (PAW)) to melt metal wire feedstock onto a substrate. The process trades precision for deposition rate: WAAM achieves 1-10 kg/hour per torch, orders of magnitude faster than powder-bed processes, but with surface finish and dimensional accuracy that require subsequent machining. This makes WAAM economically compelling for large parts (1m+) where machining-from-billet would waste material, including ship propellers, oil and gas pressure vessels, large aerospace structural components, defense platforms, and architectural elements. Build envelopes are limited only by robot reach and gantry size; multi-meter parts are routine.
The market is dominated by integrators rather than turnkey OEMs. WAAM3D (UK, Cranfield University spinout) is the academic-industrial leader. Gefertec (Germany) offers integrated WAAM cells. MX3D (Netherlands) became globally famous with the 3D-printed steel pedestrian bridge in Amsterdam and now sells industrial WAAM systems. Lincoln Electric and ESAB (welding incumbents) sell adapted WAAM-capable industrial cells. Norsk Titanium specializes in titanium WAAM for aerospace, with an FAA-qualified production line. Australian shipyard-adjacent firms (AML3D, Titomic) target defense and marine applications. The robotic-arm versus gantry distinction defines two architectural camps; KUKA, ABB, Fanuc, and Yaskawa robots are the common platform.
WAAM is in a different competitive frame than other AM processes: it competes with subtractive machining and casting more than with other AM. The 2023-2024 inflection has been defense and shipbuilding adoption. Australia's AUKUS submarine program, US Navy frigate construction, and European defense rearmament have all created procurement programs explicitly favoring WAAM-produced large structural components for cost, lead-time, and supply-chain-resilience reasons. Norsk Titanium's FAA Part 23 qualification for titanium aerostructures was a 2024 industry milestone. Hybrid WAAM-plus-CNC machining cells (Mazak, DMG Mori) bring the process directly into job-shop environments.
WAAM's trajectory is most coupled to defense and shipbuilding spending cycles. The technology is mature enough for production but has weak general-industrial demand drivers in peacetime; that is changing. Material qualification, particularly for high-strength steels and titanium aerospace alloys, is the gating concern. The biggest open question is whether WAAM can scale beyond the integrator model into a turnkey OEM business; without that, the technology remains a high-engineering-content service rather than a productized category.
