| Abstract Scope |
Vat photopolymerization-based additive manufacturing offers a versatile approach for surface modification of biomaterials. In this study, commercially available UV-LED-curable acrylic resins were applied onto titanium substrates to investigate their effect on biofilm formation. Titanium is widely used in biomedical applications but is susceptible to biofilm-related complications. Thin polymer coatings were formed via UV-LED curing, and nano-zeolite additives were incorporated to introduce potential anti-biofilm functionality. Two resins with different surface characteristics were compared to evaluate the influence of wettability and polymer chemistry. The combined effects of polymer properties and nano-scale additives on bacterial adhesion and biofilm development are discussed. This work highlights the potential of vat photopolymerization-based coatings as a practical strategy for controlling biofilm formation on titanium biomaterials. |
