Dr George Maddison

George joined the Department of Materials Science and Engineering in 2022 as the Advanced Metals Processing Engineering Lead for Additive Manufacturing. 

Prior to this he had completed 5 years of study to achieve both an MSc in Aerospace Materials and a PhD titled “In-Situ Monitoring
and Control during Laser Powder Bed Fusion of Nickel Superalloys”.

George is the manager and primary operator of the Additive Manufacturing facilities within the Royce at the University of Sheffield facilities, supporting students, other researchers, external institutions and businesses in accessing and making full use of the Additive Manufacturing
capabilities on offer. This covers Laser- and Electron Beam- Powder Bed Fusion, as well as Blown Powder Directed Energy Deposition and Binder Extrusion technologies. 

Additionally, George is the operator of the powder plasma spheroidising capabilities.

George works with a great breadth and depth of activities. As a materials scientist, he is fascinated by the possibilities that Additive Manufacturing offers to tailor material properties and behaviour within a single process and part. 

George's main interests lie in the adoption and optimisation of novel materials for Additive Processes, as well as pushing the
limits of component design and machine capability. Furthermore, Additive Manufacturing presents a unique fusion of a process and the metadata associated with it. With data collected during manufacture using novel in-situ sensors, it is possible to develop highly accurate models or “digital twins” of components that are produced via Additive methods.

Key Research Interests:

• In-situ monitoring during Additive Manufacturing
• Digital Twinning of Additive processes and components
• Qualification methods for Additively Manufactured Materials
• Novel and difficult-to-process materials for Additive Manufacturing
