Abstract

With the rapid development of 3D printing technology, it has penetrated various fields. In the context of global oil resource scarcity and increasing emphasis on environmental protection, developing high-performance bio-based 3D printing materials is a crucial means to overcome the limitations of petroleum resources and achieve sustainability. This paper proposed a "green" development method for high-performance, sunlight-curable vat photopolymerization 3D printing resins based on soybean oil and itaconic anhydride. Utilizing bio-based itaconic anhydride to replace traditional petroleum-based materials, a novel UV-curable prepolymer, IPESO, with 80.37 % high bio-carbon (C_bio) content and no volatile substances was synthesized. Simultaneously, a series of resins, IPESO-ETPTAx, with high mechanical and thermal properties were obtained utilizing ethoxylated trimethylolpropane triacrylate (ETPTA) as a diluent. Samples printed with IPESO-ETPTA40 achieve a high resolution of 40 µm on the xy-axis. This advanced material has broad application prospects in the field of vat photopolymerization 3D printing and provides a new strategy for the development of plant oil-based vat photopolymerization 3D printing resins.

用于高分辨率 3D 打印的大豆油衍生紫外线固化树脂的绿色合成方法

随着 3D 打印技术的快速发展，它已渗透到各个领域。在全球石油资源紧缺、环境保护日益受到重视的背景下，开发高性能生物基3D打印材料是突破石油资源限制、实现可持续发展的重要手段。本文提出了一种基于大豆油和衣康酸酐的高性能阳光固化大桶光聚合3D打印树脂的 "绿色 "开发方法。利用生物基衣康酸酐替代传统的石油基材料，合成了一种新型紫外光固化预聚物 IPESO，其生物碳（Cbio）含量高达 80.37%，且不含挥发性物质。同时，利用乙氧基化三羟甲基丙烷三丙烯酸酯（ETPTA）作为稀释剂，获得了一系列具有高机械和热性能的 IPESO-ETPTAx 树脂。使用 IPESO-ETPTA40 印刷的样品在 x 轴上的分辨率高达 40 微米。这种先进的材料在大桶光聚合三维打印领域具有广阔的应用前景，并为植物油基大桶光聚合三维打印树脂的开发提供了一种新策略。
