AI Technical Summary
The limited availability of photoactive resins for 3D printing poses challenges in achieving desired material properties, particularly in terms of mechanical properties and antimicrobial capabilities, with existing acrylate-based systems resulting in highly crosslinked, inhomogeneous networks with inferior mechanical properties.
Development of a polymeric chain comprising imidazolidinyl urea monomers, which can be crosslinked, alkylated, halogenated, or conjugated to drugs, forming a photocurable resin suitable for 3D printing, offering antimicrobial properties and improved mechanical behavior.
The developed resin achieves high-resolution 3D printing with excellent antimicrobial properties against bacteria, maintaining cytocompatibility and blood compatibility, and tunable thermal and mechanical properties, making it suitable for biomedical applications.
