About the Project
Additive manufacturing (AM) or 3D printing is a manufacturing technology where parts are made layer by layer. The AM technology has the capability to fabricate complex parts with short lead time. In binder jetting AM, binder via printer head is used to join the metal powder selectively layer by layer and fabricate green parts. The absence of heat source eliminate the natures issues associated with AM technologies including the rapid heating & cooling, columnar microstructure and residual stresses. Sintering process is then used to consolidate the green parts and achieve fully dense components. In this project, binder jetting AM will be utilised to fabricate high strength alloys. The project will include process optimisation, development of sintering regime and evaluation of the subsequent effects on microstructure and mechanical properties. Finite element modelling will be also utilised to assess the shrinkage that occurs during the sintering process.
