PhD Studentship: Additive Manufacturing of Graded Metallic Parts

University of Nottingham - Engineering

Location: University Park

Supervisor: Prof Richard Hague

Innovation in the automotive industry is currently driven by stringent CO2 emission targets that are being implemented worldwide. Many are the approaches investigated to reduce CO2 emissions, with light-weighting being one of the main areas of research for most car manufacturers. One of the strategies to reduce weight in cars is that of improving the structural efficiency of the bodies in white. This requires the replacement of conventional steels with higher performance alloys. The progressive introduction of new high-performance alloys requires however complex joining of multiple metallic materials with the risk of creating weak spots and effectively limiting the actual design possibilities. 

The existing commercial metal Additive Manufacturing techniques are inherently mono-material and therefore have never been considered to realise such assemblies. The Centre for Additive Manufacturing (CfAM) has however recently developed a new MetalJet technique that can be used to print components out of several different metals in one piece. This is accomplished by coordinating the jetting of dissimilar materials on a base substrate, so that components with spatially varied composition can be directly created by dispensing different metal droplets within the same building process. This enables the unique opportunity to 3D print components with several different properties throughout, eliminating the need for any welding or riveting procedures.

We are interested in working with a student who could lead the maturation of this multi-metal MetalJet technique that will no doubt open up a sea of opportunities. This will require the complete understanding of the MetalJet printing process as well as the compatibility of dissimilar materials within the printed structure. Of particular importance will be the study of the interface between the different material droplets as this determines the ultimate success of the printed structures. This research will be conducted within a wider research team comprising of academics, post-doctoral researchers and technical staff. Operating as part of a collaborative aim, this experimental research will build on the experience already developed in the group and collaborating industrial partners.

The ideal candidate should have experience and/or a strong interest in additive manufacturing, materials science, metallurgy and general material characterisation techniques.
