4D printed thermally activated self-healing and shape memory polycaprolactone-based polymers (2018, background): “Unlike other 4D printed smart materials, SMPs require a thermo-me-chanical programming process, also called constrained-thermo-me-chanics, to be transformed from a permanent shape to a temporary one and vice versa [38].”
