Abstract :
Stereolithography (SLA), which is one of the additive manufacturing techniques, uses ultraviolet light to cure photopolymers layer by layer with high spatial resolution and surface quality. The mechanically simple design of the SLA systems allow for precise process control and optimization of the process for various photocurable polymers and their nanocomposites with different nanoparticles. Silver nanoparticles have attracted the interest of researchers due to their unique optical, electrical, and antibacterial capabilities, which make them promising candidates as additives in the preparation of polymer nanocomposites with functional properties. In this study, UV-curable polymer nanocomposites are prepared with the addition of different contents of silver salt via SLA technique for use in antibacterial applications. The effect of AgNO3 addition on the curing of the resin was investigated by using UV-visible spectroscopy and FTIR. In-situ synthesis of AgNPs was achieved during the SLA process without any additional treatments. The nanocomposites containing 0.3% AgNO3 showed improved mechanical properties.
