Photopolymerization is one of the most popular 3D printing techniques in additive manufacturing in engineering, health, jewelry, or any area where the primary need is to manufacture parts with high dimensional resolution at a low cost and without process complications. Today, in sustainable energy systems such as solar panels or solar water heaters, the sunlight is used to transform solar energy into electrical or thermal energy, therefore, various designs have been made to effectively capture the sunlight. The plano-convex lenses are characterized by their property to concentrate the light on a single point and, for that reason, become strong candidates to catch the sun's rays. In this study the design of the three-dimensional models of convex lenses will be developed considering their dimensions and functionality; the material’s properties with Ultraviolet–visible spectroscopy (UV/Vis), refraction index and thermogravimetric analysis, in order to print the resin lenses with UV LCD technology. The performance of the lenses was analyzed by testing their light concentration properties and their resistance to sunlight in a field test. Additionally, three-dimensional models simulated with the TracePro software were made in order to compare the results with empirical evidence.
