Abstract
The influence of UV post-curing process on mechanical propertie s as well as photocuring conversion ratios is presented. An analytical model to determ inate the conversion ratio for frontal polymerization is used to define 3D printing parameters in ord er to obtain a conversion profile as homogenous as possible. The mechanical properties of 3D printed coupons with and without UV post-curing process were obtained through experimental tensile and bending tests. Furthermore, the experimental conversion ratios of printed samples were obtained by means of FTIR spect rometry analysis. It was observed that conversion ratios and some mechanical properties increase because of UV post-curing trea tment, enabling the chance to optimize the whole manufacturing process in function of the 3D printed part requirements
