MX3D Raises €7M to Scale Metal WAAM Tech Across Energy, Nuclear & Industrial Sectors

On May 13, 2025, NX3D secured €7 million in its Series A funding round, spearheaded by EDF Pulse Ventures with backing from ING Sustainable Investments and PDENH. This capital injection reflects growing investor confidence in Wire Arc Additive Manufacturing (WAAM) as a viable alternative to traditional metal manufacturing techniques, especially for large, complex, and high-value components. WAAM’s appeal lies in its ability to reduce waste—by more than 80% according to MX3D—while potentially compressing lead times and offering greater design flexibility.

Operationally, a key priority for MX3D is to scale capacity. The company is expanding its Amsterdam facility by adding six systems capable of printing metal parts of up to 20 tonnes, bringing its total system count to 15. Some units will focus on R&D (materials, MetalXL software) while others support its Print-on-Demand model. This infrastructure scaling is paired with establishing external reseller and supply partnerships, particularly exemplified by a recent alliance with Phillips Corporation aimed at serving U.S. federal customers.

In terms of market positioning, MX3D is increasingly being trusted with mission-critical industrial use-cases. Customers noted include the BMW Group, Framatome, and the U.S. Army. The nuclear sector figures prominently—MX3D was selected to provide WAAM systems for Framatome’s new €26 million additive facility in Romans-sur-Isère, France, which will produce components for reactors, cooling circuits, and propulsion systems, promising lead-time reductions of up to 50% versus forging/casting. Under the Series A arrangement, observer-director seats were granted to representatives from EDF Pulse Ventures and PDENH—solidifying not just financial, but governance alignment.

Strategic implications of this funding and customer traction are manifold. First, the investment by EDF, a major energy utility with nuclear operations through Framatome, signifies a broader interest in additive technologies to boost sovereignty, reduce dependence on external supply chains, and improve sustainability metrics. Second, securing certification (ISO 9001, API 20S) indicates readiness to penetrate regulated and safety-critical sectors. Third, material R&D and software development are being positioned as adjacent differentiators—if successful, they could help MX3D extract higher margins and reduce costs.

Despite these positives, several risks and open questions require monitoring. WAAM technologies historically face challenges around repeatability, quality control (e.g. microstructure consistency, weld defects), post-processing, and certification timelines. Scaling to 15 machines and entering sectors like nuclear will test MX3D’s process control and supply chain. Financially, Series A funding is modest relative to capital demands for such heavy industrialization. Long-term success likely hinges on larger contracts, possibly subsidized industrial policy in Europe and the U.S., and close execution on R&D, certification, and sales growth.
