摘要

As one of the core advanced manufacturing technologies, additive manufacturing is of high application value in the aerospace, biomedical, and industrial component manufacturing fields. Nevertheless, current additive manufacturing materials (e.g., petroleum-based resins) face limitations such as poor stability, limited shape recovery, and insufficient mechanical properties, which restrict sustainable manufacturing progress. Inspired by the stress-dissipation mechanism in plant cell walls, we develop a cellulose-based photopolymerizable resin that delivers exceptional stiffness-deformability synergy and spatiotemporally shape memory capability. These structures integrate excellent mechanical strength and rapid recovery performance after deformation. The additive manufacturing cellulose-based photopolymerizable resin material exhibits a synergistic stiffness-deformability profile, achieving a compressive strength of 115.42 MPa and stiffness of 1404.16 MPa. These characteristics lay the foundation for specialized defense components, energy absorption systems, and spatiotemporal memory materials.
