Customized tracheal design using 3D printing of a polymer hydrogel: influence of UV laser cross-linking on mechanical properties
Journal Title: 3D Printing in Medicine - Year 2019, Vol 5, Issue
Abstract
The use of 3D printing of hydrogels as a cell support in bio-printing of cartilage, organs and tissue has attracted much research interest. For cartilage applications, hydrogels as soft materials must show some degree of rigidity, which can be achieved by photo- or chemical polymerization. In this work, we combined chemical and UV laser polymeric cross-linkage to control the mechanical properties of 3D printed hydrogel blends. Since there are few studies on UV laser cross-linking combined with 3D printing of hydrogels, the work here reported offered many challenges.
