"It’s difficult to manufacture complex tissue constructs with the necessary mechanical properties and structure integrity when you’re with bioprinting in soft tissue engineering. Typically, scientists will use materials, like PCL, to reinforce the inside of 3D bioprinting constructs, but the long degradation period is not great. But a team of researchers – Pei Zhuang, Wei Long Ng, Jia An, Chee Kai Chua, and Lay Poh Tan – from Singapore’s Nanyang Technological University have proposed a novel UV-assisted, extrusion-based (UAE) 3D bioprinting method that could help fabricate soft tissue constructs with the desired structural integrity. The team lays out their work in a paper titled “Layer-by-layer ultraviolet assisted extrusion-based (UAE) bioprinting of hydrogel constructs with high aspect ratio for soft tissue engineering applications.”
