Aconity3D WireDED: Three Metals, One Build, No Machine Changes
3D PrintingAconity3D has released a multi-material wire-based directed energy deposition system capable of processing up to three different metals in a single build — without requiring the machine to be significantly reconfigured between materials.
The capability addresses one of the persistent constraints in industrial metal additive manufacturing: the assumption that changing materials means changing machines, workflows, or at minimum, the build chamber setup.
The AconityWIRE System
The AconityWIRE uses a coaxial wire-feeding head mounted on a 6-axis robot arm with a 2-axis turn-tilt table, giving it the geometric flexibility to deposit material on complex surfaces that fixed-gantry systems cannot reach. The laser source is a 1000W or 1200W fiber laser. Build volume is 400 x 780mm. The system can heat the substrate to 500°C, which is relevant for materials like Inconel and titanium that require elevated preheat temperatures to prevent cracking during deposition.
The validated material set covers the major industrial wire feedstocks: aluminum, stainless steel, Inconel, and titanium. The multi-material capability — three materials in a single build — is enabled by the coaxial nozzle design with shielded gas delivery, which allows rapid wire switching without the contamination risk that makes material changes difficult in powder-bed systems.
Rosenheim Technical University of Applied Sciences is already operating a multi-material head from Aconity3D, providing independent research data on the system’s capabilities.
The Market It Targets
Aconity3D positions AconityWIRE explicitly for MRO (maintenance, repair, and overhaul) applications — a market where the ability to repair rather than replace components has compounding economic value. A turbine blade with a worn leading edge made of Inconel, repaired by depositing Inconel wire onto the existing substrate rather than casting a replacement, represents the core use case. The same logic applies in energy (oil, gas, mining, nuclear infrastructure), military and expeditionary manufacturing, and large tooling and mold applications where wear surfaces can be built up locally in a harder material than the base structure.
The automotive and aviation applications are more incremental — large chassis components and structural aviation parts where DED’s scale advantage over powder-bed systems becomes relevant.
The direct competitors Aconity3D names are Meltio and Hybrid Manufacturing Technologies, both of which offer wire-based or hybrid approaches to metal AM. Aconity3D’s differentiation is the multi-material capability in a single coaxial head rather than sequential single-material deposition runs.
The So What
Multi-material metal AM has been a research target for years; the AconityWIRE moves it into a commercially available system. The implications are most significant for MRO and repair applications, where the economics of depositing a few hundred grams of Inconel to extend the service life of a component worth tens of thousands of dollars are immediately compelling. For buyers evaluating industrial metal AM systems, the relevant question this launch raises is whether single-material capability is a long-term constraint — and for applications where part geometry involves material transitions or requires different properties in different zones, the answer increasingly appears to be yes.
