- Profile
-
Kamran Mumtaz is a lecturer in the Department of Mechanical Engineering. He has a first class degree in Aeronautical Engineering from the University of Salford, Manchester, an MSc in Manufacturing Management and a PhD from Loughborough University.
- Research interests
-
Kamran's research is in the area of Additive Manufacturing (AM) (also known as 3D printing and Rapid Manufacturing), a layer by layer process which produces fully functional parts directly from a CAD model.
Kamran has been involved in AM since 2005 and specialises in metals process and materials development. He has worked with a number of AM technologies such as Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS) and Electron Beam Melting (EBM) processing a variety of aluminium, cobalt, nickel, steel and titanium alloys for aerospace, automotive and medical industries.
He has completed a range of research projects, publishing widely and winning two international best paper awards. He has worked closely with industry users of AM, focusing on understanding the limitations of the technology in a manufacturing environment and commercialisation of new materials.
Kamran is also involved in multi-material deposition during AM, producing functionally graded components allowing the user to tailor specific properties across a component. He is interested in AM of ceramics and has worked with grading from metal to ceramic materials for turbine blade applications.
