Abstract Based on the recently received promising results on plant oil-based epoxy acrylate (EA) as an important type of free-radical UV-curable bio-based prepolymers, reassuring the merits of facile synthesis, less pollution, low energy consumption1,2,3, this research was realized for additive manufacturing applications purposes. Bio-based prepolymer formulations were based on soybean oil epoxidized acrylate (AESO) oligomer that was blended with specific functional acrylic monomers to increase flexibility, water resistance4, tensile strength and adhesion properties5. System was polymerized by using various concentrations of 2,4,6-trimethylbenzoyldiphenylphosphine oxide (TPO) photoinitiator with absorption band at 379 nm and two different types of UV-light source: LED and laser. Systems crosslinking kinetics, depending on TPO concentration and UV-light source was investigated by Fourier Transformation Infrared spectrometry (FTIR) and RAMAN spectroscopy. Crosslinking network characteristics and gel fraction were also obtained.
