Annotation: Substitution of petroleum-derived materials with plant-based materials in polymer synthesis is beneficial due to their low toxicity, reduced dependence on finite fossil resources, and lower greenhouse gas emissions. Vanillin is one of a few bio-based and aromatic compounds that are industrially available. In recent years, vanillin and its derivatives attracted a huge interest of scientific community as valuable source of monomers for polymer synthesis. The aim of this work was to develop new vanillin-based photocross-linked polymers for microtransfer molding and optical 3D printing technologies. During this study six series of vanillin-based polymers and one separate resin were developed and the influence of vanillin derivative, comonomers and photoinitiator to the properties of the resulting polymers was investigated. Vanillin acrylate-based resin and vanillin dimethacrylate-based resins with tridecyl methacrylate and 1,3-benzenedithiol are suitable for application in microtransfer molding, as they were able to replicate unique features of the target. Photosensitive dual-curable resin composed of vanillin dimethacrylate, acrylated epoxidized soybean oil and pentaerythritol tetrakis(3-mercaptopropionate) is suitable for optical 3D printing technology as it showed high printing accuracy and good layer adhesion.
