Justin's paper on preheating gelatin is published. We demonstrated preheating gelatin extended its 3D printing time compared to freshly prepared gelatin and enhanced the printability of the ink, which is essential for extrusion-based bioprinting and food printing. Congratulations Justin and Cheng Pau!

Cheng Pau successfully completed his PhD qualification exam! Now officially PhD candidate. Congratulations!
Many thanks to the panel members, Professor Simpson, Professor Tan, and Professor Leo.
Azusa and Jason's paper on ECM-based microchannels demonstrating interstitial flow has been published. We demonstrated to fabricate ECM-based microfluidic devices to mimic interstitial flow through ECM. The interstitial flow allowed controlling the chemical environment at the surface of the hydrogel, which can regulate cellular response.
This work is led by Azusa (Keio U, a former visiting student to SUTD) and Jason. Shun (Keio U) and Rahul contributed to this work. Many thanks to Prof. Onoe for amazing collaboration!

Jason's last official day at SUTD. We wish you the best in your future endeavors Dr. Goh!
Jason successfully completed his PhD defense and the revision of the thesis! First Ph.D. from the group and we are proud of his achievement. We are thankful to all committee members, Professor Yang, Professor Ai and Professor Fernandez, for continuing encouragement and advice.
Congratulations Dr. Goh!
Cheng Pau's paper on 3D printing of milk-based product is published. We developed a method to print 3D structures consisting of milk (consisting of powder milk and water). The entire process is carried out at room temperature, which will find applications in 3D printing of materials containing temperature-sensitive nutrients. Congratulations Cheng Pau and Rahul!

James's paper on fabrication of paper-based analytical devices using a toner laser printer is published. This work is particularly important because the popular wax printer has been discontinued. As toner requires longer time for penetration than wax upon heating, we addressed the associated problem of cellulose pyrolysis. Congratulations!

Azusa's paper on ECM-based stretchable microchannels is published and highlighted as an inside cover of the issue. Many thanks to Professor Onoe for leading this collaboration.
Azusa and Jason demonstrated to fabricate perfusable and stretchable microchannels using 3D-printed sacrificial molds. Azusa visited SUTD from Keio University as a part of collaboration. We also thank Mr. Itai and Professor Miura for realizing this work.

Congratulations Azusa, Jason and everyone!
Rahul's recent work on embedded ink writing (EIW) has been highlighted in EurekAlert. We studied to print polysiloxane in surrounding fluids to control wettability. Congrats Rahul, Terry and the team!
