A New Blueprint for UK Aerospace: GKN Aerospace Joins £38M Sustainable Manufacturing Initiative

The aerospace industry is at a critical juncture, navigating the dual pressures of technological advancement and a global mandate for sustainability. In a significant move to address these challenges head-on, GKN Aerospace has joined a landmark £38 million UK research and innovation programme known as DECSAM (Digitally Enabled Competitive & Sustainable Additive Manufacturing). This four-year initiative, led by Airbus, represents a concerted effort to redefine the future of aircraft component production, placing sustainability and digital integration at its core.

At the heart of this programme is Additive Manufacturing (AM), or 3D printing, a technology with the potential to build lighter, more complex, and resource-efficient parts. While methods like laser powder bed fusion (L-PBF) are already certified for flight, their widespread adoption has been hampered by productivity bottlenecks, a fragmented digital workflow, and a heavy reliance on international supply chains. The DECSAM programme is designed to dismantle these barriers, creating a cohesive, end-to-end AM ecosystem entirely within the United Kingdom.

By uniting 11 of the UK’s leading aerospace manufacturers, technology specialists, and research institutions, the project aims to forge a new path for the sector. The goal is not merely to improve existing processes but to build a scalable, cost-effective, and environmentally conscious manufacturing framework. This initiative is poised to strengthen the UK’s sovereign industrial capabilities, reduce the carbon footprint of aviation, and secure a competitive edge in the next generation of aerospace technology.

The DECSAM Programme: Forging a Sustainable and Sovereign Supply Chain

The DECSAM initiative is more than just a research project; it’s a strategic investment in the UK’s industrial future. With £38 million in funding from Innovate UK, the Aerospace Technology Institute (ATI), and the Department for Business and Trade, the programme is structured to deliver tangible results over its 48-month timeline, running from June 2024 to June 2028. Its mission is to create a digitally connected, highly productive, and sustainable domestic supply chain for aerospace-grade additive manufacturing.

A Vision for Integrated Manufacturing

The core vision of DECSAM is to tackle the primary obstacles limiting the scalability of AM in aerospace. The programme is structured around three key pillars: performance, productivity, and scalability. To enhance performance, the consortium will focus on developing new and improved metal alloys and physics-driven design methodologies that maximize the potential of 3D printing. This allows for the creation of components that are not only lighter but also stronger and more efficient than their traditionally manufactured counterparts.

On the productivity front, the project will explore the use of high-power lasers, advanced beam shaping, and sophisticated in-situ monitoring to speed up the printing process without compromising quality. By embedding real-time quality assurance into the production line, DECSAM aims to reduce post-processing and inspection times significantly. Finally, scalability will be achieved by developing a comprehensive “digital thread” that connects every stage of the process,from raw material sourcing to final part certification,and by designing automated, sustainable factory concepts ready for volume production.

A crucial element of this vision is strengthening the UK’s domestic capabilities. By “on-shoring” critical processes like material development and heat treatment, the programme aims to build a more resilient and self-sufficient UK aerospace sector. This reduces dependence on overseas suppliers, shortens lead times for critical components, and ensures that the UK can compete globally in the high-value manufacturing landscape.

The Power of a Unified Consortium

The strength of the DECSAM programme lies in its collaborative foundation. Led by Airbus, the initiative brings together a formidable team of 11 organizations, each a leader in its respective field. This consortium includes global giants like GKN Aerospace, AM technology pioneers like Renishaw plc, and standards bodies such as ASTM International UK. It also features innovative SMEs and vital research hubs, including Authentise Ltd, The Manufacturing Technology Centre, Additive Manufacturing Solutions Ltd, and the University of Sheffield, among others.

This collaborative approach ensures that expertise from every part of the AM value chain is integrated into the project. From developing sustainable feedstock and recycled powders to creating the software for in-process monitoring and establishing clear guidelines for part certification, the consortium covers all bases. This holistic strategy is designed to accelerate the adoption of AM by providing a proven, end-to-end solution that the wider industry can trust and implement.

“Additive manufacturing can unlock new efficiencies in aerospace, lowering costs, optimising material use, reducing weight, and consolidating complex assemblies into single parts. DECSAM unites a strong consortium to accelerate adoption in civil aerospace, aligning closely with the ATI’s additive manufacturing strategy to drive future economic growth and sustainability.” – Jacqueline Castle, Chief Technology Officer at the Aerospace Technology Institute (ATI)
