Open Architecture Additive Manufacturing (OAAM)
TWI is taking the lead in the Open Architecture Additive Manufacturing (OAAM) project to demonstrate the ability to manufacture large metallic components via Additive Manufacturing (AM) for the benefit of UK Aerospace. The OAAM programme plans to develop directed energy deposition (DED) AM technologies that can be scaled up to accept multi-metre component sizes. TWI will work with project partners Airbus, Autodesk, Cranfield University, Glenalmond Group, University of Bath, University of Manchester and University of Strathclyde to create three DED AM process platforms. These new platforms will enable aerospace manufacturers and their supply chains to develop advanced AM manufacturing concepts in the following fields:
1. Arc-wire / Laser-wire AM @ Cranfield University.
2. Electron Beam wire AM @ TWI (Cambridge).
3. Laser-powder / Laser-wire AM @ TWI (Yorkshire Technology Centre).
Each of these systems will offer unique AM capabilities and address a number of common needs:
• Scalable architecture solutions, with common CAD/CAM control interfacing.
• Integrated process steps (NDT, Machining, Inspection, Cold-work etc.) as necessary for optimum implementation to aerospace requirements.
• Ability to manufacture aerospace components using AM to TRL 6 or MCRL 4/5.
These new AM systems will be truly state-of-the-art research facilities for their respective AM process variants, and will be made available to UK industry, leveraging key expertise resident within the hosting research organisations. They will establish a fully quantifiable process that will place UK suppliers at the forefront of the technology and AM research. This will offer the UK aerospace sector access to next-generation manufacturing with a simplified, lower risk route to support AM’s industrialisation and rapidly deploy into aircraft platforms. A substantial amount of results overspill onto other sectors (energy, marine, etc.) is also foreseen.
Prof. Robert Scudamore is Associate Director and Group Manager for Joining Technologies and Additive Manufacturing at TWI. TWI is a Research and Technology Organisation (RTO) that focuses on industrially driven research and innovation. He is also Director of the Additive Manufacturing Innovation Centre, a joint initiative recently started with Lancaster University, and Vice Chair of AM UK.
Robert' has technical expertise in laser AM of various metals, including high temperature materials, for repair and original part build (LMD and SLM).
