Biography:

Dr. Jerry Fuh is a Professor at the Department of Mechanical Engineering, National University of Singapore (NUS) and the Co-Director of NUS Centre for Additive Manufacturing (AM). He is a Fellow of SME and ASME and a PE from California, USA. He obtained his BS degree in Mechanical Engineering from National Jiaotung University, Taiwan in 1980, an MS in Manufacturing and a PhD in Mechanical Engineering in 1985 and 1992 respectively from the University of California at Los Angeles (UCLA), USA. He also worked in aerospace, automation and CAD/CAM industry in Southern California for five years before joined NUS in 1993. Dr. Fuh has devoted himself to the research of Additive Manufacturing (AM) processes or 3D Printing (3DP) since 1995. He and his colleagues have established the NUS's AM/3DP research programme focusing on biomedical applications and set up an advanced 3DP laboratory through several research & development grants with industrial collaborations. As a result of his research on AM/3DP, 60 international-refereed papers were published related to the AM/3DP processes and 15 to AM material developments together with 4 book chapters and 12 patents. A book entitled "Laser-Induced Materials and Processes for Rapid Prototyping" was published by Kluwer Academic, MA in 2001.

In 2005, he received the IES Prestigious Engineering Achievement Award for the work on "Development of Rapid Prototyping Technologies for Precision and Biomedical Engineering" from the Institute of Engineers, Singapore (IES) in recognition of outstanding engineering skills which have made notable contributions to progress engineering in Singapore. He has published over 350 technical papers in manufacturing and design, and supervised over 80 graduate students with over 50 are PhD students. He also serves in more than 10 refereed journals as Editor, Associate Editor or Editorial Board Members related to design, manufacturing and AM/3DP.


Abstract:

Fabrication of Cell-laden Tissue Engineering Scaffolds via Combined Inkjet and E-jet Bioprinting Techniques
 
Cell-laden tissue engineering (TE) scaffolds were proven to have a better performance in terms of cell growth compared to cell-less scaffolds. Traditionally, cells are pipetted on to the scaffolds. However, precise positioning and homogeneous distribution of cells on a scaffold is nearly impossible through this method, which would lead to a poor replication of the natural tissue structure.

In this work, a piezoelectric inkjet printing technique named drop-on-demand (DoD) was combined with electro-hydrodynamic jetting (E-jetting) method to fabricate cell-laden scaffolds. DoD printing parameters were optimized to obtain suitable droplet size deposited on
 scaffolds. Cells were then seeded on the E-jetted scaffolds using both the DoD method and traditional pipetting, and the performance were compared.  Comparing to the traditional pipette method, DoD cell printing method is a more effective cell seeding method. It could distribute cells at desired positions with required patterns on the scaffolds precisely. The combination of DoD and E-jetting method could be used to fabricate evenly distributed cell-laden scaffolds, which will aid in replication of complex structure of natural tissues and organs in future.
