Hydrogels are synthetic polymers with the ability to swell, frequently used as bio-inks in 3D bioprinting. They are especially useful in drug delivery applications because their swelling behavior can be closely controlled by adjusting factors such as the polymer material, viscosity, and shear stress.

The primary types of bio-inks used in 3D printing include:

- **Hydrogels**: Synthetic polymers with the ability to swell. They are especially used in drug delivery applications, with swelling controlled by factors such as polymer material, viscosity, and shear stress.
- **Ceramic-Based Inks**: These provide high stiffness and a surface for bone tissue development. Common materials like hydroxyapatite and tricalcium phosphate enhance scaffold strength.
- **Polymer-Based Inks**: Materials like polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) are extensively used for engineering applications, prototyping, and assisting in bone formation and regeneration.
- **Composite Inks**: Combinations of different inks (e.g., hydrogels and polymers) that enhance mechanical properties and bioactivity. They accelerate healing and are primarily used in tissue engineering applications.
