The fracture mode of the tensile specimen and the corresponding SEM tensile fracture morphology (a) 0.1–525 °C–H–180° ductile fracture; (b) 0.1–445 °C–H–45° semi-brittle fracture; (c) 0.2–445 °C–V–180° interlayer debonding (d) 0.3–525 °C–V–45° brittle fracture. (F1 represents the direction of tensile force; F2 represents the printing path; F3 represents the printing direction).
