About the project
About the Project 3 Year Self funded project This PhD project will ignite an exciting new research area for the sustainable production, consumption and recycling of metallic materials for use in Metal Additive Manufacturing (AM) processes. Building on a strong track-record of AM research at Cardiff University, dating back to the mid-1990s, the research will initially investigate the synthesis of metal powders from recycled machining chips/production scarp obtained from conventional machining processes, followed by process optimisation to allow this powder to be used for producing components by metal AM processes, such as powder bed fusion and binder jetting. The conventional production of metal powders for AM (via gas or water atomisation) requires a series of extraction and cleaning processes which use enormous quantities of energy. The powder compositions must also be tailored when they are synthesised from crude metals/metal alloys. With the proposed research route, the energy footprint of producing metal powders will be dramatically reduced. Chips will be collected after machining from titanium blocks/bars whose compositions are already tailored during casting/forging. Thus, the processing time to produce tailor-made powders will also be considerably reduced. The resulting AM parts will be characterised for surface and mechanical integrity and will be validated via performance test. The impact of the research will underpin cost effective waste management of metallic chips and their recycling for the use in powder form when producing high-value AM components. The High-Value Manufacturing (HVM) Research Group of Cardiff University has recently acquired a state-of-the-art metal binder jetting machine. Through this project, the student will have an exceptional opportunity to gain experience on the novel metal binder jetting AM technology.
