Shape memory polymers (SMPs) are materials capable of changing their structural configuration from a fixed shape to a temporary shape. and vice versa when subjected to a thermal stimulus. The present work has investigated the 3D printing process of a shape memory polymer (SMP)-based polyurethane using a material extrusion technology.
