Additive Manufacturing (AM) is one of the rapidly developing techniques that may be used to prototype complex structures and sophisticated geometries are typically challenging produce with conventional methods. Thus, replacing petroleum-based plastics renewable resources increasingly important for additive manufacturing (3D printing) photocurable resins. The use biobased in AM a feasible alternative traditional plastics. Henceforth, development sustainable inks has gained substantial interest modern polymer industry by reducing its environmental impact. In this context, vegetable oil valuable plant-based source expected an alternate feedstock 3D printing due broad spectrum applications, affordable price, potential biodegradability. perception, present work demonstrates soybean oil-based resins (ESBO_HEA/HEMA) application digital light processing (DLP) photopolymerization. At first, acrylated/methacrylated was efficiently synthesized from corresponding epoxidized one-pot oxirane ring-opening strategy as acrylated (AESO) generated via acrylation between ESO acrylic acid. A series DLP have been formulated using acrylate/methacrylate presence photoinitiator (TPO) or reactive diluents (trimethylolpropane triacrylate, TMPTA). Moreover, rheological properties especially resin's viscosity all were investigated, which good agreement printing. Additionally, impact diluent (TMPTA) on thermal (DSC, TGA) mechanical (DMA, tensile strength, hardness) behavior 3D-printed object also examined. Altogether, research inexpensive oil, offered simple method prepare could make architectural models automotive components, opens new avenues sustainable.

This study presents a sustainable approach to transform waste cooking oil (WCO) into multifunctional 3D-printable photocurable elastomer with integrated self-healing capabilities. A linear monomer, WCO-based methacrylate fatty acid ethyl ester (WMFAEE), was synthesized via sequential strategy of transesterification, epoxidation, and ring-opening esterification. By copolymerizing WMFAEE hydroxypropyl acrylate (HPA), novel developed, which could be amenable molding using an LCD light-curing 3D printer. The resulting WMFAEE-HPA exhibits exceptional mechanical flexibility (elongation at break: 645.09%) autonomous room-temperature properties, achieving 57.82% recovery elongation after 24 h 25 °C. Furthermore, the material demonstrates weldability (19.97% retained 12 80 °C) physical reprocessability (7.75% retention initial reprocessing). Additional functionalities include pressure-sensitive adhesion (interfacial toughness: 70.06 J/m2 on glass), thermally triggered shape memory behavior (fixed -25 °C reversible deformation/recovery ambient conditions), notable biodegradability (13.25% mass loss 45-day soil burial). Molecular simulations reveal that unique structure monomer enables dual mechanism room temperature without external stimuli: chain diffusion entanglement-driven gap closure, followed by hydrogen bond-mediated network reorganization. synergy between diffusion/entanglement dynamic bond reorganization allows system achieve balance integration. Moreover, integration these attributes highlights potential this WCO-derived for various possible printing applications, such as flexible electronics, adaptive robotics, environmentally benign adhesives, so on. It also establishes paradigm converting low-cost biowastes high-performance smart materials through precision molecular engineering.
