Collagen is another widely used biomaterial that has found popularity in commercial applications, such as photography. Collagen has more recently been used in tissue engineering applications, by creating hydrogels that provide structure to engineered tissue. This video introduces collagen as a biomaterial, demonstrates how it is harvested from porcine skin, and shows how the material is used to create a hydrogel for tissue engineering applications. Finally, several applications of the material...

FAQs
Two design features determine how this material behaves after printing: collagen’s cell-interactive properties support biological engagement, while the formulation’s viscosity allows extrusion through the printer. Once deposited, physical or chemical crosslinking stabilizes the layers into a three-dimensional hydrogel. Together, these features connect biological function with shape retention in engineered constructs.
Crosslinking stabilizes the printed collagen layers after extrusion, helping the deposited material form a persistent three-dimensional hydrogel rather than remaining only a loose formulation. Researchers may use physical or chemical crosslinking, depending on the selected bioink system. This stabilization is central to producing structured scaffolds and cell-laden constructs for bioengineering studies.
Recombinant collagen bioink can provide greater compositional control and reproducibility than some animal-derived materials because the collagen is produced through genetic engineering. It may also improve biosafety in comparison with certain directly extracted sources. These characteristics are especially relevant when researchers need more consistent biomaterial formulations for tissue-mimetic scaffolds or experimental models.
Preparation begins by dissolving the recombinant collagen or blending it into a cell-compatible formulation. The mixture is adjusted so its viscosity supports extrusion, then deposited layer by layer to create the intended three-dimensional structure. Finally, physical or chemical crosslinking stabilizes the printed layers as a hydrogel, producing a construct suitable for subsequent bioengineering applications.
Viscosity determines whether the collagen formulation can be extruded in a controlled manner during printing. The material must remain compatible with the cells and sufficiently structured to support deposition as successive layers. Appropriate viscosity therefore links the formulation stage to the quality of the resulting three-dimensional architecture, while later crosslinking provides additional stabilization.
In bioengineering, the resulting constructs can serve as tissue-mimetic scaffolds, cell-laden models, or three-dimensional systems for regenerative medicine. They also support disease research and drug testing, where researchers can investigate biological responses within collagen-based structures. The combination of compositional control and printable organization makes the approach useful across these experimental contexts.
