Novel and sustainable solutions are needed for surface water treatment. Photocatalytic TiO2 is studied but not directly deployable into natural bodies due to settling poor recoverability. This research capitalizes on a convergence of the emerging technologies 3D printing biocompatible polymer (polylactic acid, PLA) composites, nanotechnology, advanced oxidative processes immobilize customizable, high area, deployable, retrievable structures with localized kinetic specificity harmful algal blooms (HAB). PLA-TiO2 composites at varying loadings (3–34 %) were extruded as feedstock fused filament fabrication (FFF) enabling low cost design freedom photocatalyst (disks, lattices). Large lattices printed PLA highly loaded (34 % w/w) TiO2. Prior HAB cyanotoxin experiments, photocatalytic performance lattice (t1/2 = 0.8 h) under UV light confirmed comparable free 0.9 h). Under environmentally relevant solar simulation, photocatalysis by successfully reduced microcystin (MC) 3 faster than photolysis alone 36 Lattice mediated MC in presence cyanobacteria cells 11 was 58 slower water-only treatment cell activity attenuation. reduces local pH, promoting adsorption degradation. foundational novel composite optimization reactive area prototyping enabled scale-up structures, applicability traditional contaminants.
