== Abstract ==

The photopolymerization-based additive manufacturing process, including 3D printing techniques such as stereolithography and digital light processing, has undergone considerable development over the last few decades. These techniques provide flexibility in the physical and chemical properties of 3D printed materials. The photopolymerization process is based on ultraviolet (UV) curing of liquid-state monomers/oligomers in the presence of photopolymerizable photoinitiators, which is known as the UV irradiation curing process. The UV light intensity has a significant effect on the reactivity and solidification process, modeling which has many challenges. In this work, we present a novel model that determines the required UV light intensity in the photopolymerization process. To make meaningful predictions of the UV light intensity influence on the curing process, it is essential to appropriately model the UV light waves. Maxwell’s equations are considered for this purpose. The photopolymerization process itself is described by the reaction-diffusion equation, which is coupled to Maxwell’s equations in a unit square of the resin. Isogeometric analysis is used to discretize the produced coupled system of equations. We present numerical results that demonstrate the light intensity influence on the UV curing process.
