Bioink Preparation: Bioinks, which are slurries of living cells and biocompatible materials, are prepared. These bioinks must have properties conducive to cell growth and tissue development.
Bioprinting Phase:
Layered Deposition: The bioprinter deposits the bioink layer by layer as per the digital model. This precision layering ensures the correct architecture and distribution of different cell types needed for the organ to function.
Materials and Technology: Various printers such as inkjet, micro-extrusion, and laser-assisted bioprinters are used, each having its unique advantages based on the type of tissue or organ being printed.
Post-Bioprinting Phase:
Maturation: The printed structure, often referred to as a pre-tissue, is incubated in a bioreactor. Here, it matures to form vascularized, functional tissue.
Testing and Validation: Rigorous testing is conducted to ensure that the printed organ functions effectively and is safe for implantation.
Scientific Principles
Cell Proliferation and Differentiation: Techniques in bioprinting rely heavily on the ability of stem cells to proliferate and differentiate into specialized cells, thereby constructing a functional tissue scaffold.
Biomechanics: The mechanical properties of both the scaffold and the bioink are crucial for creating durable and flexible tissues that can withstand the dynamic environment of the human body.
Biocompatibility: All materials used in bioprinting must be biocompatible—to support cell functions without eliciting an immune response—since they must integrate seamlessly with native tissues.
