New Paper Accepted into 3D Printing and Additive Manufacturing

December 07, 2020

The paper titled " High-Resolution Novel Indirect Bioprinting of Low-Viscosity Cell-Laden Hydrogels via Model-Support Bioink Interaction.”


Bioprinting of unmodified soft extracellular matrix into complex 3D structures has remained challenging to fabricate. Herein, we established a novel process for the printing of low-viscosity hydrogel by using a unique support technique to retain the structural integrity of the support structure. We demonstrated that this process of printing could be used for different types of hydrogel, ranging from fast crosslinking gelatin methacrylate to slow crosslinking collagen type I.

Project featured as Namic's success story 

December 04, 2020

This project aims to use 3D bioprinting technology to reconstruct the Asian skin model, which closely mimics the biochemical and physiological properties of human skin. The project also aims to develop an Asian skin-on-a-microfluidic plate device to establish a high-throughput screening method, improve productivity and repeatability, and to enable the development of new qualitative measurement protocols.


New Paper Accepted into Acta Materialia

December 02, 2020

The paper titled " Resolving the porosity-unmelted inclusion dilemma during in-situ alloying of Ti34Nb via Laser Powder Bed Fusion.”


In this paper, we present a mechanism to achieve simultaneous reduction of inclusion content and porosity in in-situ alloyed Ti34Nb samples. Such achievement marks a significant breakthrough in the process optimization of in-situ alloying with LPBF​. A patent based on the study has also been filed – “High Speed Homogenization And Pore Mitigation Strategy For In-Situ Alloying Via Laser Powder Bed Fusion (LPBF)”.

Latest paper accepted for publication in Macromolecular Bioscience

September 28, 2020

The paper titled "Bioprinting of Collagen: Considerations, Potentials and Applications."

Why is it so difficult to print collagen-only bioink? In this article we dived deeper into the issue from a bottom-up approach to find out why bioprinting collagen has shown limited success. Key research areas that would enhance the functionality of bioprinted collagen are highlighted.
