7. Towards 4D printing
The textile backing or reinforcing thread can be a shape-memory thread, in which case it is sensitive to certain stimuli such as temperature, electric current or light. Its shape then evolves over time, which is known as 4D printing
Figure 28 shows an example of a knitted fabric with shape-memory wire insertion. Initially flat, the knitted fabric is deformed and then returns to its initial shape under the effect of temperature.
