Popis: 3D printing technology has become a valuable and successful tool for many areas, including materials sciences. Nanoparticle thin film fabrication commonly requires expensive, highly specialized equipment not available in basic sciences laboratories. A simple, inexpensive, and straightforward methodology for the deposition of thin films composed of semiconductor TiO2 nanoparticles using a DLP (Digital Light Processing) 3D printer is presented in this work. X-ray diffraction (XRD), Raman, Ultraviolet–visible (UV–Vis), and Photoluminescence (PL) spectroscopies were used to study the film's structural and optical properties. By analyzing Scanning Electron Microscopy (SEM) micrographs, particle size distribution and film thickness were studied. Single-layer TiO2 (anatase) thin films with thickness around 114.3 ± 39.5 nm were successfully deposited through DLP 3D printing. The deposited films can be used in sensors, energy harvesting, catalysis, hydrogen production, and other UV light applications.
