Additive manufacturing (AM) is one of the most promising technologies for producing complex and personalized components, offering advantages such as reduced time, costs, and material waste compared to traditional processes. Among the various techniques, liquid crystal display (LCD) vat photopolymerisation (VPP) distinguishes itself for its elevated precision and the possibility of developing new polymeric compounds and testing them in the vat. However, most of the resins used nowadays are fossil-based and show problems related to sustainability and end-of-life material handling. This work aligns with this context, aiming to develop and characterise a new bio-based thermosetting resin compound starting from Acrylate epoxidized soybean oil (AESO) as the primary matrix.
