| Abstract Scope |
The advancement of additive manufacturing has driven the search for improved materials. Among these, photocurable resins stand out for their versatility and precision. However, they often exhibit fragile mechanical behavior and limited durability. This study aims to investigate the effect of titanium dioxide (TiO₂) reinforcement on the properties of a UV-curable acrylate resin used in SLA/LCD 3D printers. Samples were prepared by incorporating different concentrations of TiO₂ (0.5%, 1.0%, and 1.5%) into the base resin. Mechanical characterization was conducted following an accelerated aging protocol. It was observed that the 1.5% concentration compromised printability, preventing successful fabrication. Meanwhile, the 0.5% and 1.0% concentrations influenced the mechanical properties of the printed parts, with varying degrees of improvement. The results suggest that titanium dioxide can serve as a functional additive for enhancing specific properties in 3D-printed components, but only at low concentrations to maintain processability |
