Cartilage tissue presents challenges in terms of repair and regeneration due to its inherent limitations
in self-healing and the scarcity of available donors. Cartilage damage can result in the development of joint
problems characterized by symptoms, such as pain, swelling, and osteoarthritis. Collagen scaffolds are extensively
used as biomimetic substances for cartilage engineering due to their ability to offer structural, biochemical,
and mechanical signals for chondrocytes. Nevertheless, traditional techniques for producing collagen scaffolds
frequently yield inadequate pore architecture, diminished mechanical robustness, and restricted form accuracy.
Hence, 3D printing is a developing method that can surpass these restrictions by allowing accurate manipulation
of the shape, porousness, and makeup of the scaffold. 3D printing has the capability to include various
materials and cells in the scaffolds, resulting in the production of intricate and personalized tissue structures.
This research examines the latest progress in utilizing 3D printing to create collagen scaffolds for the purpose of
regenerating cartilage. This text discusses the different sources of collagen, methods of cross-linking, techniques
for printing, and strategies for post-processing that are employed to improve the performance of scaffolds.
Furthermore, it discusses the difficulties and potential future paths of utilizing 3D printing to create collagen
scaffolds for the purpose of regenerating cartilage.
