About the project
About the Project Project Overview Material Extrusion (MEX) remains the most widely adopted 3D printing technology globally. The market for desktop systems continues to expand, driven by decreasing hardware costs and increasing software sophistication. However, despite these advancements, desktop MEX processes are still constrained by fundamental limitations due to their mode of operation. Most notably, in mechanical anisotropy and issues with surface quality and geometric precision. This PhD project seeks to move beyond incremental software updates and parameter optimisation, to explore novel approaches to the MEX process that could underpin the next generation of MEX manufacturing systems. Innovative process augmentations, hardware architectures and control strategies will be explored, designed, tested and integrated, to mitigate against the inherent weaknesses of the extrusion process. This work is intended to expedite high-performance functional 3D printing in an affordable and accessible desktop format. Research Aims The successful candidate will lead research into the design and development of augmented and improved MEX processes. Key areas of investigation include: Machine & Process Innovation: Designing and building bespoke experimental platforms that improve on current extrusion paradigms. Experimental Validation: Conducting rigorous system characterisation tests to benchmark new developments against current state-of-the-art systems, and hone system implementation. System Integration: Exploring how the developed techniques can be combined to produce a potential blueprint for the next generation of MEX manufacturing systems. Essential Requirements: A First or Upper Second-class honours degree (or equivalent). Proficiency in mechanical design and implementation. Experience with hands-on "maker" technologies (e.g. 3D printing, CNC, electronics). Strong analytical skills and an interest in advanced manufacturing. Fluency in written and spoken English. Desirable Skills: Coding proficiency (Python, C++, or G-code manipulation). Experience in hardware/software development, mechatronics and/or robotics. A passion for designing and creating new machines and systems. How to Apply: To apply, please email christopher.cox@bristol.ac.uk with [PhD Application + Your name] in the subject line.
