Abstract
For the development of high strength resin for SLA (stereolithography) 3D printing technology, VTES (vinyltriethoxysilane)-coated ZrO₂-CNF (carbon nanofiber) particles were prepared by hydrolysis and condensation reactions, and then highly dispersed in a commercial photopolymer (High-temp) by the IPN (interpenetrating network) phenomena. The surface morphology of VTES-coated ZrO₂-CNF particles according to CNF contents were observed by FE-SEM, and particle size distribution was measured using a particle size analyzer. The viscosity and dispersion stability of VTES-coated ZrO₂-CNF/High-temp composite resins were investigated by a rheometer and Turbiscan, respectively. The cross-sectional images of 3D-printed objects was observed by FE-SEM, and the mechanical properties of 3D-printed objects (ASTM-D638 Type V) were investigated through a tensile test and nanoindenter.
