In this work, machine learning has been applied to predict the tensile strength of the 4D printed materials.
The morphology of the 4D printed materials was determined by scanning electron microscope (SEM).
The stimuli that can be applied to the 4D printed parts can be in form of physical and chemical interactions, in which the material has to be stimulus-responsive active materials [4].
