Loughborough University is a top-ten rated university in England for research intensity (REF2014) and an outstanding 66% of the work of Loughborough’s academic staff who were eligible to be submitted to the REF was judged as ‘world-leading’ or ‘internationally excellent’, compared to a national average figure of 43%.

In choosing Loughborough for your research, you will work alongside academics who are leaders in their field. You will benefit from comprehensive support and guidance from our Graduate School, including tailored careers advice, to help you succeed in your research and future career.

Full Project Detail:
Conventional round laser beams of symmetric energy distributions are recognised as a fundamental contributor to the issues surrounding the quality of additively manufactured components. The use of custom re-profiling with computer generated diffractive optical elements (DOEs) enables the modification of beam irradiance profiles with the purpose of creating deposits with improved material properties and physical characteristics.

This PhD project will involve collaborative work and supervision with the industrial partners Renishaw plc to develop new understanding of metal depositions and optical control for advanced powder bed additive manufacturing technologies. The work will include studying the 3D temperature distribution, fluid flow and cooling rates in materials produced by custom DOEs. Physical and microstructural property improvements from such an approach will be investigated.

There will be opportunities to attend academic conferences, industrial visits for collaboration and other training courses to develop a wide variety of technical and transferrable skills throughout the project.
