3D printing of cellulose acetate (CA)-based, sustainable, thermally stable nanocomposites is challenging due to their fast drying, nozzle clogging, and complex rheological behavior. In this study, we developed an extrusion-printable ink based on CA nanocrystals (CNCs) using a trisolvent wet blending method, followed by postprinting pore-inducing processing technique. The performed well in both tensile- compression-based mechanical tests. Moreover, the demonstrated malleable deformation during compression testing without any premature fracture, unlike commercial commodity plastics. thermal stability was assessed thermogravimetric analysis, showing ∼ 28 °C improvement onset degradation temperature after addition 5 wt % CNCs. Solvent tolerance tests against various solvents indicated excellent solvent resistance. lightweight showed no deterioration, even long-term exposure water vapor. Finally, anticorrosion behavior samples evaluated as coating material for metal (Al), demonstrating protection corrosive acid vapors. Thus, application 3D-printed exhibits significant promise implementation fields lightweight, anticorrosive engineering materials.
