Dr James Murray is a Senior Research Fellow in the Department of Engineering at the University of Nottingham. He research involves technical innovations in metal re-use, to prevent unnecessary re-melting or disposal. He is particularly interested in innovations in metal swarf re-use for additive manufacturing, ultimately asking – can we replace new expensive powder with waste low value metal? His work also involves innovations to improve the lifetime and value of metal powders in additive manufacturing. He is currently exploring routes to enable metal re-use in industry.
