Recently,Norsk Titanium,the global leader in wire-based additive manufacturing,has officially signed a Collaborative Research Agreement (CRA) with Airbus,the world's major aerospace giant.The two parties will jointly advance the airworthiness certification and large-scale industrial adoption of the Rapid Plasma Deposition (RPD) process for high-load primary structural components made of premium titanium alloys in aviation,accelerating the transformation of manufacturing methods for titanium parts used in commercial aircraft.
This in-depth cooperation outlines four core focus areas:establishing a supporting system for mass production of the RPD process,securing full-process airworthiness qualifications for titanium alloy components,unifying industrial standards for dedicated titanium alloy wire feedstock,and developing new formulations of aerospace-grade titanium materials.The partners aim to fully integrate the RPD additive manufacturing process into Airbus' standardized production system,laying solid engineering and compliance foundations for the mass deployment of this technology across its new aircraft programs of all variants.
Prior to the conclusion of this cooperation agreement,Norsk Titanium had already achieved a critical technical milestone.The lower fuselage frame component for the A350,fabricated via its proprietary RPD process,has obtained dual airworthiness certifications from both the Federal Aviation Administration (FAA) of the United States and the European Union Aviation Safety Agency (EASA).As one of the world's additively manufactured titanium alloy structural components for commercial aviation with dual airworthiness approvals,the highest structural safety rating and the largest overall dimensions,this component has entered stable full-scale mass production.
In terms of technical principles,RPD falls under the Directed Energy Deposition (DED) category of additive manufacturing technologies.It achieves near-net shaping by melting titanium alloy wire layer by layer through a plasma arc,with only minimal precision machining required post-forming to meet specification requirements.Compared with conventional forging processes,this technology drastically improves the utilization rate of costly titanium alloy raw materials and shortens the overall manufacturing lead time,making it particularly suitable for producing large-scale,complex curved load-bearing titanium alloy parts for aerospace applications.
From a global industrial market perspective,the aerospace sector has emerged as the primary market for the commercialization of DED wire-fed additive manufacturing technology.A notable shift is underway in the industry's development trajectory:additively manufactured titanium components are no longer limited to laboratory validation of individual prototypes,but are transitioning into a new phase of standardized,systematic mass application.As leading enterprises including Airbus and Norsk Titanium continue to streamline the full industrial chain spanning process,materials and certification,wire-based additive manufacturing will expand its application scope throughout the commercial aviation supply chain,driving cost reduction and efficiency improvements across the high-end titanium manufacturing industry.
