One of the major challenges in 4D printed Shape Memory Polymers (SMPs) is their slow response to thermal stimuli. Synthetic carbon fillers have been introduced address this issue; however, use comes with environmental concerns. On other hand, Polylactic Acid (PLA) commonly used for 3D/4D printing SMPs, but it requires softening achieve large deformations. This research paper introduces a sustainable solution through blending PLA Polybutylene Adipate Terephthalate (PBAT) that not only addresses these also possesses eco-friendliness due PBAT's high biodegradability rate. PBAT weight percentages 15 %, 30 and 45 % utilized soften PLA, composites are successfully printed. Mechanical properties, shape memory effects, morphology, behaviors comprehensively investigated. The results show excellent features such as 220 elongation 93 recovery just few seconds. two PLA-PBAT blends complete less than 8 s. contains PBAT, addition strength (40 MPa), has 17 elongation. This, coupled low melting temperature drives Scanning electron microscopy images finally confirm printability all three blends, composite containing exhibiting best quality layer interfaces least porosity.
