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’ll work alongside academics who are leaders in their field. You will benefit from comprehensive support and guidance from our Doctoral College, including tailored careers advice, to help you succeed in your research and future career. 

Project detail

The PhD scholarship is part of the EPSRC Centre for Doctoral Training (CDT) in Additive Manufacturing in collaboration with the University of Nottingham, University of Liverpool, Loughborough and Newcastle University.

The studentship starts with a 1 year expert training programme in Additive Manufacturing where the students will be based at the University of Nottingham. The following 3 years will based at Loughborough University where the PhD research program will be carried out.

The focus of this project is on wax 3D printing for the investment casting process.

In investment casting, the wax injection process has traditionally been used to produce wax patterns. However, wax injection moulds are relatively expensive and take a long time to produce.

Additive manufacturing has already been in use within this industry for printing wax patterns. This method offers fast development capability, prototyping opportunity, and cost effective solutions to mass productions of low-quantity orders.

However, the disadvantages of the existing printing wax methods are: cost, inability to print large patterns, rough surface finish comparing to injected wax and limited dimensional accuracy.  

This research aims to develop an additive manufacturing process for the wax pattern production in investment casting process as an alternative to the conventional wax injection process. The initial phases for both PhD projects include:

  • Understanding the investment casting process and its requirements
  • Understanding the wax injection specs, process and its requirements as reference point for additive manufacturing (alternative solution).
  • Design and develop a wax 3D printing process for investment casting application
  • Validation of the process in industrial application.

The industrial partner is a French lost-wax casting company with a worldwide reputation in industrial gas turbine industry for manufacturing hot section parts.

Entry Requirements

Applicants should have, or expect to achieve, at least a 2:1 Honours degree (or equivalent) in Engineering, material science or a related subject.

A background in additive manufacturing is not essential as training will be provided through the CDT. Experience in manufacturing environments is an advantage. Part of the research (in the 2nd and 3rd year of the programme) may be done at the company’s base, flexibility to travel and stay in France, and French language skill is highly desirable.

Applicants must meet the minimum English Language requirements, details available on the website.

Fees and funding


Tuition fees cover the cost of your teaching, assessment and operating University facilities such as the library, IT equipment and other support services. University fees and charges can be paid in advance and there are several methods of payment, including online payments and payment by instalment. Special arrangements are made for payments by part-time students.

Please note that this studentship will be awarded on a competitive basis to applicants who have applied to this project and/or job advert ref: AMCDT_InvestCast1 & AMCDT__SABET_Bio01 which have been prioritised for funding.

If awarded, this 4 year studentship will provide a provisional tax-free stipend of £14,786 p.a, plus tuition fees at the UK/EU rate. Please be advised that, due to funding restrictions, the studentship is only available to students eligible for UK/EU fees.
