3D Bioplotter Research Papers

Researchers have looked to cartilage tissue engineering to address the lack of cartilage regenerative capability related to cartilage disease/trauma. For this, a promising approach is extrusion-based three-dimensional (3D) printing technique to deliver cells, biomaterials, and growth factors within a scaffold to the injured site. This paper evaluates the printability of chitosan scaffolds for a cartilage tissue engineering, with a focus on identifying the influence of drying technique implemented before crosslinking on the improvement of chitosan printability. First, the printability of chitosan with concentrations of 8%, 10%, and 12% (w/v) was evaluated and 10% chitosan was selected for further studies. Then,…
