SUTD researchers’ new approach finds that 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.
Possible states of 3D printed gelatin with transglutaminase. A) Ideal state of 3D printed gelatin with transglutaminase. B) Clumps forming due to solidification of gelatin ink with transglutaminase, reducing printing time. C) Uneven printing due to solidification of gelatin ink with transglutaminase in the nozzle.
Researchers from the Singapore University of Technology and Design (SUTD) demonstrated a simple yet effective approach to increase the printing time of gelatin by preheating it before mixing the gelatin with transglutaminase.
