A two-dimensional finite element model of the photopolymerization of a sensitive resin in a stereolithography apparatus is proposed as a tool for predicting and optimizing formulation and printing parameters. By considering light illumination, chemical reaction and heat transfer in a resin exposed to a moving UV laser source, this first approach accounts for monomer-to-polymer conversion and polymerization rate in agreement with experimental results obtained by FT-IR monitoring and the use of semi-empirical models. The temperature gradient along the exposed photosensitive material was also estimated. By varying the photoinitiator content and simulating the addition of an absorbing filler via the molar extinction coefficient, it was shown that a higher photoinitiator concentration and the presence of strongly absorbing fillers lead to a reduction in the light penetration depth, which can result in structural defects without adaptation of the layer thickness to be printed.
