Project 1: Laser welding additive manufacturing of materials and structures for
marine and offshore applications
Supervisor: Associate Professor Zhou Kun
presents a particular suitability for joining of metals and their alloys due to
high precision, high-energy concentration, small deformation, rapid processing
potentials and easy setup for automation. Laser welding-based additive
manufacturing has been used to assemble large-scale structures from their
components and remanufacture existing parts in automobile, marine engineering,
aerospace and biomedical applications. This project focuses on methodologies of
laser welding additive manufacturing of metallic materials and structures for
marine and offshore applications. The effect of processing parameters on the
microstructural features, mechanical and corrosion properties of additively
welded joints and printed structures will be investigated. The heat-affected
zones of the welded joints will be analyzed to understand the weld pool
evolution. The corrosion resistance and mechanical performance (hardness,
tensile, fatigue, impact and fracture toughness properties) of the additively
welded metals will be compared with the ASTM standard. Numerical modelling will
be conducted to understand the temperature distribution and residual stresses
during laser welding additive manufacturing for guiding process optimization. A
damage mechanics approach-based model will also be established to predict the
mechanical behavior and fatigue lifetime of additively welded structures for
quality control. This research will provide valuable knowledge on the
development of laser welding additive manufacturing in the applications of
marine and offshore.
Project 2: Non-destructive characterization of material microstructure from
Supervisor: Assistant Professor Fan Zheng David
Co-supervisor: Associate Professor Yeong Wai Yee
mechanical performance of structural elements has long been connected with the
microstructural features of materials constituting them. Microstructural
variations have often been thought to be the reason behind performance
variabilities in otherwise identical components. However, controlling the
microstructural signature of additive manufacturing is a challenging task.
While electromagnetic NDE techniques such as Electron backscatter diffraction
(EBSD) and X-ray tomography could potentially yield a very fine insight into
the volumetric internal structure of components, they are often expensive, time
consuming and not easily implementable on practical samples or environments. In
this PhD work, ultrasonic methods, which is portable and cost-effective, will
be explored to characterize material microstructure, including texture mapping
and grain size distribution.
Project 3: Bioprinting and tissue engineering via microfluidics technology
Supervisor: Associate Professor Yeong Wai Yee
In this project, an ultrafine microfluidics system will be utilized to deposit biomaterials and cells.
The project includes developing the governing physics of cell jetting, formulation of materials for microfluidics printing and also developing a proof of concept tissue printing applications.
This is an interdisciplinary project involving physics, materials, cell culture and tissue engineering.

Project: 3D printing of multi-porosity ceramic membranes for process intensification
Supervisor: Associate Professor Yeong Wai Yee
Co-supervisor: Assistant Professor Chong Tzyy Haur
Ceramic membranes are widely used in liquid filtration and waste treatment. Conventional ceramic membranes are homogeneous in microstructure and multiple membrane systems with different porosity and pore size have to be used in a typical process flow. This is usually associated with increased cost and process inefficiency.
3D printing is new manufacturing technology that allows freeform custom design and low cost fabrication at low production volume. With recent development in 3D printable ceramic materials, there is an opportunity to apply 3D printing to the design and fabrication of new ceramic membranes. Therefore, we propose to 3D print a multi-porosity ceramic membrane for process intensification. In this research, design, simulation, fabrication and characterization of the new ceramic membranes will be carried out.
