Abstract:
at photopolymerization is a precise 3D printing technique used for complex geometries with excellent surface quality, relevant in aerospace, automotive, and biomedical fields. It cures liquid resins layer by layer using light. Its advancement depends on the development of suitable materials. This work focuses on acrylic/epoxy vitrimer systems with dual-curing properties, forming joints by manual assembly instead of multimaterial printing. Mechanical and thermal behaviours are studied under isostrain and isostress conditions, both experimentally and via FEM simulations. Damping capacity is evaluated through DMA to assess vibration applications. The materials show both rigid and elastic behaviours, tested under tensile and thermomechanical conditions.
