Highly functional bio-based methacrylate and acrylate resins were synthesized from epoxidized sucrose soyate (ESS) and incorporated into formulations for stereolithographic (SLA) printing. These formulations were compared to a commercial SLA resin and with formulations where the bio-derived resins were replaced with commercial urethane acrylates. The tensile, flexural, rheological, and thermomechanical performances of the respective formulations and their prints were compared. All of the formulations were able to be printed satisfactorily with a Peopoly Moai SLA 3D printer. The acrylated ESS resin showed the highest viscosity while the methacrylated ESS resins had lower viscosities than the control urethane acrylates. The prints made from the formulations containing the methacrylated ESS resins had similar Tgs to that of the urethane acrylate control formulations while the prints from the acrylated ESS resin had a lower Tg. The tensile and flexural properties were consistent with the Tg values in terms of modulus, but some of the prints showed surface cracking that compromised the strength properties. This study demonstrated the ability of a bio-derived material to be functionally modified and incorporated into an SLA formulation and printed in different orientations.

基于光刻的生物基功能化蔗糖酯树脂增材制造的探索
由环氧化蔗糖大豆酸酯（ESS）合成高功能的生物基甲基丙烯酸酯和丙烯酸酯树脂，并将其掺入用于立体平版印刷（SLA）的配方中。将这些配方与商用SLA树脂以及将生物衍生树脂替换为商用聚氨酯丙烯酸酯的配方进行了比较。比较了各自配方及其印刷品的拉伸，弯曲，流变和热机械性能。所有配方都可以用Peopoly Moai SLA 3D打印机令人满意地打印。丙烯酸酯化的ESS树脂显示出最高的粘度，而甲基丙烯酸酯化的ESS树脂的粘度低于对照聚氨酯丙烯酸酯。由包含甲基丙烯酸酯化ESS树脂的配方制成的印花具有相似的T gs与聚氨酯丙烯酸酯对照制剂的相比更低，而来自丙烯酸酯化的ESS树脂的印刷品具有较低的T g。拉伸和挠曲性质与T g值在模量方面一致，但是一些印刷品显示表面开裂损害了强度性质。这项研究证明了将生物来源的材料进行功能性修饰并掺入SLA制剂中并以不同方向印刷的能力。
