Abstract Biological structures provide inspiration for developing advanced materials from sustainable resources, enabling passive structural morphing. Despite an increasing interest parsimony‐oriented innovation, shape‐changing based on renewable resources remain underexplored. In this work, the architecture of a single plant fiber cell wall (S 2 , instance) is simplified to design novel concepts 4D printed tubular moisture‐driven actuators, using hygromorphic properties continuous flax (cFF) reinforced materials. This new class bioinspired active referred as metabiocomposites. Before design, are produced with customized rotary 3D printer, qualified, and tested sorption behavior. A parametric experimental, analytical, FEA analysis highlights programmability material through effects mesostructural parameters (printing inclination α) geometric factors (operational length L, inner diameter D, thickness h) actuation authority. The overall performance trade‐off between rotation torque, energy density comparable that source inspiration: natural fibers wall. potential applications illustrated proof concept meteosensitive rotative structure transmits motion external device, such solar tracker.
