The 3D printing of functional aerogels, particularly those incorporating additives, represents a transformative approach in materials science, enabling the creation of highly customizable structures with advanced properties. This study introduces a 3D printing methodology for fabricating aerogel structures infused with titanium dioxide (TiO2) nanoparticles, designed to enhance photocatalytic and environmental remediation applications. A commercially available 3D printer was adapted with a custom syringe pump system, allowing precise control over the extrusion of a shear-thinning aerogel ink. The ink formulation, tailored for compatibility with the system, achieved homogeneous dispersion of TiO2 nanoparticles (55-230 nm) within the silica aerogel matrix at 50 wt % relative to silica content. Postprocessing steps, including gelation in ammonia vapor and supercritical CO2 drying, preserved the intricate geometries of printed structures, which achieved a specific surface area of 407 m(2)/g and a density of 0.15 g/cm(3). Rheological analysis demonstrated the ink's suitability for 3D printing, with viscosity decreasing from 10,000 Pa
