The utilization of dynamic cross-linking represents a highly promising approach in addressing the escalating issues of plastic pollution and fossil resource consumption. Despite being extensively investigated over the past decade, various dynamically cross-linked polymers (DCPs) predominantly remain confined to the realm of academic research. To serve as a valuable material for practical application, advanced processing is always essential for all kinds of materials. 3D printing (3DP) enables the creation of intricate shapes layer-by-layer without relying on molds, thus the integration of 3DP techniques with DCPs holds significant potential to enhance and expand the practical applicability of DCPs. Here, an overview of the fundamental principles underlying DCPs compatible 3DP techniques are provided, namely photocuring 3DP, extrusion-based 3DP, and laser sintering-based 3DP. Additionally, a comprehensive summary of representative research works that specifically focus on the application of DCPs in each respective 3DP technique is presented. The performance and dynamic mechanism involved in the corresponding printing process are thoroughly discussed and comprehensively reviewed. Finally, the existing challenges and issues pertaining to further enhancing 3D printability, performance, efficiency, etc., are extensively deliberated upon, while proposing potential directions to address these concerns.

动态交联聚合物3D打印的最新进展

动态交联的利用是解决日益严重的塑料污染和化石资源消耗问题的一种非常有前途的方法。尽管在过去十年中得到了广泛的研究，各种动态交联聚合物（DCP）仍然主要局限于学术研究领域。为了成为具有实际应用价值的材料，各种材料都必须进行先进的加工。3D打印（3DP）能够在不依赖模具的情况下逐层创建复杂的形状，因此3DP技术与DCP的集成对于增强和扩展DCP的实际适用性具有巨大的潜力。此处概述了 DCP 兼容 3DP 技术的基本原理，即光固化 3DP、基于挤出的 3DP 和基于激光烧结的 3DP。此外，还全面总结了代表性研究工作，特别关注 DCP 在各个 3DP 技术中的应用。对相应打印过程所涉及的性能和动力机制进行了深入的讨论和全面的回顾。最后，广泛讨论了与进一步提高 3D 打印适性、性能、效率等有关的现有挑战和问题，同时提出了解决这些问题的潜在方向。
