PhD title: Effect of Process Stability and Scalability on Cost of Polymer Powder Bed Fusion Processes

Supervisors: Dr Martin Baumers, Prof Christopher Tuck and Prof Richard Hague

Research summary

This project will investigate how build setup and process parameters affect the risk of failed prints in polymer powder bed fusion (PBF) processes, linking this to process productivity and the cost of producing parts. Additionally, the research will explore the network effects of multiple-PBF-machine setups, and how these influence the cost and risk of failure. This research will extend our understanding of the true cost of parts produced using AM, helping manufacturers to assess when and where AM is economically feasible.

PhD title: Increasing the Production Rate of Powder Bed Fabrication

Supervisors: Prof Adam Clare, Dr Christopher Hyde, and Dr James Murray

Research summary

The time taken between conception and fabrication in additive manufacturing (AM) is generally faster than wrought parts, since there is no need to create moulds or various machining programmes. However, the time taken to simply produce one part by AM can exceed 24 hours in some instances. This research seeks to improve the production rate of Powder Bed Fusion, primarily through processing of larger layer thicknesses (typically >60µm) as well as optimisation of machine parameters and feedstock properties.

PhD title: High cycle fatigue testing and microstructure analysis of SLM-processed Inconel 718

Supervisors: Dr Christopher Hyde, Prof Ian Ashcroft and Prof Adam Clare

Research summary

Nickel-based superalloys are mostly used in the aerospace industry due to their superior mechanical performance. The project is set out to study the fatigue behaviour of Inconel 718 manufactured by selective laser melting (SLM). This is realised by testing compact-tension (CT) specimens under high cycle fatigue at room temperature.
