Abstract：
Biological polysaccharides such as cellulose, chitin, chitosan, sodium alginate, etc., serve as excellent substrates for 3D printing due to their inherent advantages of biocompatibility, biodegradability, non-toxicity, and absence of secondary pollution. In this review we comprehensively overviewed the principles and processes involved in 3D printing of polysaccharides. We then delved into the diverse application of 3D printed polysaccharides in wastewater treatment, including their roles as adsorbents, photocatalysts, biological carriers, micro-devices, and solar evaporators. Furthermore, we assessed the technical superiority and future potential of polysaccharide 3D prints, envisioning its widespread application. Lastly, we remarked the challenging scientific and engineering aspects that require attention in the scientific research, industrial production, and engineering utilization. By addressing these key points, we aimed to advance the field and facilitate the practical implementation of polysaccharide-based 3D printing technologies in wastewater treatment and beyond.
摘要：
生物多糖如纤维素，甲壳素,壳聚糖,海藻酸钠,等。,由于其固有的生物相容性优势，可作为3D打印的优秀基材，生物降解性，无毒性，没有二次污染。在这篇综述中，我们全面概述了多糖3D打印的原理和过程。然后，我们深入研究了3D打印多糖在废水处理中的多种应用，包括它们作为吸附剂的作用，光催化剂，生物载体，微型设备，和太阳能蒸发器。此外，我们评估了多糖3D打印的技术优势和未来潜力，设想其广泛应用。最后,我们谈到了科学研究中需要关注的具有挑战性的科学和工程方面，工业生产,和工程利用。通过解决这些关键点，我们的目标是推进这一领域，并促进基于多糖的3D打印技术在废水处理及以后的实际实施。
