Customized tracheal design using 3D printing of a polymer hydrogel: influence of UV laser cross-linking on mechanical properties.

ABSTRACT:

Background

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.

Methods

Polyethylene glycol diacrylate (PEGDA), sodium alginate (SA) and calcium sulphate (CaSO₄) polymer paste containing riboflavin (vitamin B2) and triethanolamine (TEOHA) as a biocompati
