Project 1:​ Additive manufacturing of bioinspired composites using magnetic colloids​

Supervisor: Assistant Professor Hortense Le Ferrand

Additive manufacturing (AM) is rapidly developing, and so are bioinspired materials. Yet, composites and ceramics that exhibit unusual combinations of mechanical properties are yet to be fabricated and upscaled using AM methods. In the past, we have developed colloidal processes that employed magnetic fields to control the microstructure of materials to mimic the mechanical properties of nacre or the change in shape of the Venus Flytrap. Now, the question relies on out to translate those technologies to AM. The candidate will explore the potential of various AM methods at the Singapore Centre for 3D Printing at NTU, Singapore to fabricate and control high resolution microstructures. Printing methods include stereolithography and ink jet printing, but not only. The project will involve particle modification, theory of magnetic manipulation and physical forces involved.

Please send your CV, motivation letter, proof of fulfilling NTU admissions requirements and recommendation letters directly to Prof Le Ferrand at Hortense@ntu.edu.sg. 


Project 2: 3D Printing Optimal Convective Conformal Cooling Channels

Supervisor: Associate Professor Duan Fei 

Conformal cooling has shown it advance in precise cooling control in many applications. The fabrication of conformal cooling channel is complex; it requires the use of advanced manufacturing methods. Additive Manufacturing (AM) or three-dimensional (3D) printing is able to fabricate 3D solid objects of all shape from digital CAD models. The key benefit of AM is that it unlocks a new level of design freedom that was not achievable with traditional manufacturing techniques. It also provides cost savings and less material wastage. Selective laser melting (SLM) method has provide a good opportunity for the effective of conformal cooling channel fabrication. In this project, we will conduct computational fluid dynamics simulation to optimize cooling parameters, then analyze mechanical stresses and thermal performance of the resulting design. The we will use SLM to fabricate the conformal cooling channel that we will design as it has capability to process materials with high thermal conductivity like stainless steel. The printing quality will be monitored by X-ray computed tomography scanning.  Furthermore, we will conduct experiments for further comparison to the convective cooling simulations. Additionally, the submerged cooling has been found to significantly enhance heat transfer, this is another area that we propose to prepare the conformal cooling path through 3D printing for improve understanding for the applications.

 

Project 3: 3D-Printed Membrane Bioreactor for Waste Water Treatment

Supervisor: Assistant Professor Zhang Yi 

Co-supervisor: Associate Professor Zhou Yan

In this project, we propose to develop a novel 3D-printed membrane bioreactor that host the quorum quenching bacteria for waste water treatment. Membrane biofouling is a serious issue that hinders the broad application of membrane technology. Recently, we developed a bio-based technology using quorum quenching mechanism to control membrane fouling and extend membrane bioreactor operating period. In order to allow the quorum quenching bacteria to survive in a mixed culture condition, we need immobilize the quorum quenching bacteria and make sure they are the dominant population in the biosystem and maintain quorum quenching function during the wastewater treatment process. Our current approach is to immobilize the quorum quenching bacteria into PAC-Alginate beads. However, the effective volume/space in this setting is relatively low given only the surface layer is active. Meantime, it would be challenging to recycle the beads from the mixed liquor which may cause bead/quorum quenching bacteria loss. We aim to develop a novel 3D-printed hydrogel lattice structure to host quorum quenching bacteria. The 3D-printed lattice structure would increase the surface/volume ratio substantially and provide highly percolated pore structure for efficient nutrient/waste exchange. The proposed structure would maximize the effective volume of the material for bacteria fixing, and increase the bioactivity per unit volume. Furthermore, the lattice structure would facilitate the recycling and reduce the loss of bacteria and membrane material.


Project 4: 3D printing of optimised titanium implant for bone replacement 

Supervisor: Associate Professor Chou Siaw Meng

Co-supervisor: Associate Professor Yeong Wai Yee

The objective of this project is to design an optimised titanium implant suitable for bone replacement.

Bone defects can result from tumour removal, severe trauma, infection, or congenital abnormalities. The greatest concern is the significant variation in bone anatomy, defect shape and size between patients. The possibility of customised manufacturing using three-dimensional (3D) printing technology has opened new horizons in the reconstruction of complex bony defects. The challenge is to create an implant which has sufficient strength yet having the appropriate porous structure for osseointegration. This project involves the design of a porous structure which osteoblasts and supporting connective tissue can migrate. Mechanical testing of the implant and cell studies will be carried out to determine the optimal structural design.



NEWRI Graduate Scholarship


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.
