Single‐Step 3D Printing of Silver‐Patterned Polymeric Devices for Bacteria Proliferation Control

This work describes the fabrication of silver-patterned polymeric devices via light-based 3D printing methods from a tailored resin. An acrylate resin containing silver nitrate (AgNO3) as precursor is employed to generate nanoparticles (AgNPs) through in situ reduction metallic salt. The silver-based processed customized stereolithography SL-3D fabricate structures with surfaces. SL-printer (emitting at 405 nm) offers possibility adjusting machine settings during process allowing for AgNPs be selectively generated by modifying laser step. Thus, photopolymerization and photoinduced formation AgNPs-based strands can sequentially achieved same light source using printable fabricated exhibit different surface features that might exploited systems working marine environment control biofilm proliferation. As proof-of-concept, antimicrobial behavior printed device tested against environmental bacterial mixed communities UV–vis spectroscopy evaluating absorbance change. Further tests, however, would needed reinforce evidence bacteria on devices.
