Illuminating the Future: Principles and Applications of Two Photon Polymerization (TPP) 3D Printing

In this project, advanced Two-Photon Polymerization (TPP) laser technology was employed to fabricate intricate microscopic 3D images of the California State University, San Bernardino (CSUSB) logo and letters, as well as the University of Nebraska–Lincoln (UNL) letters and logo. The fabrication process utilized IP-S photoresist as the foundational building block, ensuring high precision and resolution in the 3D microstructures. SolidWorks was used to design these complex models, which were then meticulously printed using TPP. To validate and analyze the quality of the structures, a Scanning Electron Microscope (SEM) and Raman spectroscopy (Zygo) were used, providing detailed insights into surface texture, structural accuracy, and dimensional integrity. This combination of cutting-edge laser technology and material analysis highlights the capabilities of TPP for creating detailed 3D microstructures, with broad potential applications in fields like nanotechnology, materials science, and engineering.
