An Evening with Asst Prof Yeong Wai Yee

We have taken our initiative on “Engaging NTU – One College at a time” to the next level with the invitation of Assistant Professor Yeong Wai Yee from NTU’s Singapore Centre for 3D Printing (SC3DP) for our fireside event held on 22 June, Wed, from 6:30 pm to 8:30 pm.

Last month, we started with inviting the Dean of the College of Engineering, Professor Chen Tsuhan. Our next strategy was to engage the staff from the College of Engineering and we did that with Assistant Professor Yeong Wai Yee.

Like many of us, Wai Yee, is a foreign talent from Malaysia. She did her undergraduate degree at NTU’s School of Mechanical and Aerospace Engineering in 2003 followed by her PhD in 2006. A true-blue NTU CoE product, after working for a number of years in the industry, Wai Yee joined the NTU staff in 2012 specifically with SC3DP as Programme Director.

SC3DP focuses on 5 sectors – Manufacturing, Aerospace & Defence, Building & Construction, Marine & Offshore, and Biomedical & Food. Wai Yee oversees the researchers in the Aerospace & Defence and the Biomedical & Food sectors.

“In general, 3D Printing is still a very expensive process. It is currently ideally suited for industries with high margins like Aerospace & Defence and Biomedical,” said Wai Yee.

In biomedical applications, the initial focus was on 3D printing of biodegradable scaffold for tissues to grow. However, interestingly, tissue cells avoided growing within the scaffold. As a result, the current research has shifted to printing cell suspensions in hydrogel in a process known as skin bioprinting. This way, the cells are printed in an environment where they can thrive. Skin is a multi-layered organ with different cell types. 3D printing is well suited to depositing cells in that arrangement.

We are excited that NTU is at the forefront of 3D Printing technology and we are proud of our alma mater. As a follow-up, we are arranging a visit to SC3DP@NTU. Please drop us a note if you are interested to join the visit.

We look forward to hearing from you, meeting you at the events and having you volunteer to help us to help each other in the days ahead.
