MAPP Lecture Series - Dr Paul Hooper

The MAPP Lecture Series [#MappLecture] began in November 2017 with a lecture by Prof. Richard Leach, University of Nottingham, and will continue in Sheffield in 2018 with regular one-hour lunchtime lectures, from experts in the field of AM. All lectures are open to external attendees and will be followed by lunch and an opportunity to speak with the lecturer.

The fourth lecture in the series will be given on 13th September at 38 Mappin Street, The University of Sheffield,  by Dr Paul Hooper, Imperial College London.

Dr Hooper is a Research Fellow in the Mechanics of Materials group in the Department of Mechanical Engineering at Imperial College London. His research focuses on additive manufacturing (AM) and he leads industry-funded projects focusing on certification of AM components. His specific interests include in-situ process monitoring, process-microstructure-performance relationships, simulation of AM processes, design for AM and new process development. He also has interests in high-strain rate material behaviour and structural integrity. He has authored 22 journal publications, has an h-index of 11 and one patent.

In-situ monitoring for additive manufacturing (AM): a revolution in process control and inspection?

Lecture Abstract: AM processes build up components on a point-by-point, layer-by-layer basis. This gives engineers unprecedented levels of design freedom. However, with this approach comes defects. Process parameters, part geometry, scan strategy and material quality all influence the fusion of material on that same point-by-point basis. In-situ process monitoring tools can give insight into how these factors influence the component quality and provide opportunities for improved process control. Inspection for quality control and certification can also be performed at the same time as the part is being built, reducing the need for costly post-build inspections. This talk will detail the development of a high-speed temperature monitoring system for laser powder bed fusion and discuss opportunities and challenges for in-situ monitoring of AM processes.

The fifth MAPP Lecture will be given by Professor Andrew Moore, of Heriot-Watt University, Edinburgh, on Monday 22nd October. Further details will be posted on this website nearer the time.
