Common examples include hydrogels, which react to moisture, and shape memory polymers, which return to their original shape after deformation.
2.2. Geometric Coding: Programming the Transformation
Geometric coding involves designing the object with specific instructions embedded in its structure. This coding determines how the material will respond to stimuli. By carefully controlling the geometry, engineers can dictate the sequence and type of transformations that occur.
2.3. External Stimuli: Triggering the Change
External stimuli act as the catalyst for transformation in 4D printing. These triggers can be physical (heat, pressure), chemical (pH levels), or electromagnetic (light, magnetic fields). The choice of stimuli depends on the smart material used and the desired outcome.
2.4. Examples in Action: Demonstrating the Process

Precise control over the printing parameters is essential to ensure the object’s structural integrity and responsiveness.
4.4. Activation: Triggering the Transformation
Once the object is printed, the transformation is activated by exposing it to the specified stimuli. For example, a hydrogel-based object may swell when immersed in water, while a shape memory polymer-based object may return to its original shape when heated. The transformation occurs autonomously, without any manual intervention.
