With the growing global population and rapid economic development, the demand for energy and raw materials is increasing, and the supply of fossil resources as the main source of energy and raw materials has reached a critical juncture. However, our overexploitation and overconsumption of fossil resources have led to serious problems, including environmental pollution, climate change, and ecosystem destruction. In the face of these challenges, we must recognize the negative impacts of the shortage of fossil resources and actively seek sustainable alternative sources of energy and resources to protect our environment and sustainable development in the future. Three-dimensional (3D) printing, an additive manufacturing technology, has been used in many fields to manufacture complex and high-precision products. While traditional manufacturing processes typically produce large amounts of waste and emissions that are harmful to the environment, 3D printing is much more energy efficient compared to traditional manufacturing methods, which helps to lower energy costs and reduce reliance on non-renewable energy sources. The development of low-carbon and environmentally friendly 3D printing materials can help to reduce carbon emissions and environmental pollution and realize the goal of sustainable development. Lignin, as the second largest renewable green biomass resource after cellulose, has great potential for manufacturing low-carbon and environmentally friendly 3D printing materials. This review presents some recent studies on the applications of lignin and its derivatives in photo-curing 3D printing, including the preparation and performance of lignin-based photosensitive prepolymers, lignin-based reactive diluents, lignin-based photo-initiators, and lignin-based additive. This review also provides recent studies on the preparation and performance of lignin-based thermoplastic polymer for Fused Deposition Modeling (FDM) 3D printing. Finally, the future challenges and industrialization prospects of lignin-based 3D printing materials are discussed.
随着全球人口的增长和经济的快速发展，对能源和原材料的需求不断增加，而作为主要能源和原材料来源的化石资源供应已达到关键阶段。然而，我们对化石资源的过度开采和过度消耗已经导致了严重的问题，包括环境污染、气候变化和生态系统破坏。面对这些挑战，我们必须认识到化石资源短缺的负面影响，并积极寻求可持续的替代能源和资源，以保护我们的环境和未来的可持续发展。三维（3D）打印是一种增材制造技术，已在许多领域用于制造复杂和高精度的产品。虽然传统制造工艺通常会产生大量对环境有害的废物和排放物，但与传统制造方法相比，3D 打印更加节能，有助于降低能源成本并减少对不可再生能源的依赖。开发低碳环保的 3D 打印材料有助于减少碳排放和环境污染，实现可持续发展的目标。木质素作为仅次于纤维素的第二大可再生绿色生物质资源，在制造低碳环保 3D 打印材料方面具有巨大的潜力。本综述介绍了木质素及其衍生物在光固化 3D 打印中的一些最新应用研究，包括木质素基感光预聚物、木质素基反应性稀释剂、木质素基光引发剂和木质素基添加剂的制备和性能。本综述还介绍了木质素基热塑性聚合物用于熔融沉积建模（FDM）3D 打印的最新研究。最后，讨论了木质素基 3D 打印材料的未来挑战和工业化前景。
