Iain Todd

MAPP EPSRC Future Manufacturing Hub

Don’t blame the metals: looking at additive manufacturing from the Material Perspective.

What makes an alloy suitable for use in additive manufacturing? Is the composition or the form in which it arrives? It is the process conditions we select?

Certain metals and alloys can have reputations for being “unprocessable” or “difficult” to use in AM. Indeed, many of them are, but recent high profile publications and research has highlighted that by applying understanding gained from research and practice in other fields of metallurgy that some of the issues we have can be resolved. In this talk I will look at the characteristics of metals and alloys that make them seem unpromising and seek to present some ideas as to how we may work to resolve them so that we can realise the potential of AM processes in as wide a range of applications as possible.


Iain Todd is based at the University of Sheffield where he directs the EPSRC Future Manufacturing Hub In Manufacture using Advanced Powder Processes (www.MAPP.ac.uk). He presently holds the RAE/ GKN Aerospace Research chair in Additive Manufacture and Advanced Structural Metallics. His work lies at the interface between manufacturing technology and materials processing science and concerns the development of understanding of underlying physical principles related to materials processing to better control material form, integrity and function and hence economic value. Research in his group is conducted in close collaboration with Industry and on an appropriate scale to allow rapid transition of new laboratory discoveries into industrial practice.
