About the Project
Motivated by an ever-growing demand for patient customisation, the overall aim of this project is to investigate the potential of 3D printing for the fabrication of custom-built medical implants. More specifically, we will target a titanium-based alloy (Ti-alloy), which is already widely employed as an implant material in its more traditional forged form.
Increasing life expectancy is driving the need for enhanced health care solutions, so we can all live more comfortably for longer. Besides hugely improved pharmaceuticals, innovation in materials plays a key role in this arena. For example, medical implants, ranging from stents for heart attack patients to artificial joints for victims of falls, are central to maintaining an excellent quality of life. Concerning the future of such implants, rapid fabrication of patient-specific solutions is a highly appealing target, e.g. manufacture of a hip implant on site in a hospital and immediate insertion. Such local fabrication facilities would speed up a patient’s recovery, enhancing their experience and minimising costs. Moreover, they would be invaluable to areas of the world where access to suitable supply chains is fraught with difficulty.
One promising candidate for on-site custom-manufacturing of implants is 3D printing, which is well suit to high-value/low-volume production. However, the properties of 3D printed materials are often remarkably different to those produced by more traditional routes. Hence effort is required to understand these differences at the micro-to-nano scales, as well as their impact on macro-performance. This project targets this area, focusing on a common Ti-alloy. The surface structure, chemistry and relevant properties of 3D-printed and more traditional forged Ti-alloy samples will be compared to identify key differences and similarities. On the basis of these results, routes to enhance functionality through both optimisation of the 3D printing recipe and surface engineering will be explored. Given a positive outcome, potential industrial stakeholders will be approached for commercial exploitation.
Applicants must have obtained, or be about to obtain, at least an upper second class honours degree or the equivalent qualification gained outside the UK, in an appropriate area of science, engineering or technology.
UK applicants interested in this project should make direct contact with the Principal Supervisor to arrange to discuss the project further as soon as possible. International applicants (including EU nationals) must ensure they meet the academic eligibility criteria (including English Language) as outlined before contacting potential supervisors to express an interest in their project. Eligibility can be checked via the University Country Specific information page (https://www.manchester.ac.uk/study/international/country-specific-information/).
Some restrictions apply to applicants from certain Asian countries. In general, students from Europe, the Americas, Africa, Australia, New Zealand, Korea and Japan are eligible to apply for the programme. Unfortunately, we cannot accept applications from south-east Asian countries such as Singapore, China and Malaysia.
