This review aims to provide an overview of sustainable approaches that can be incorporated into well-known procedures for the development of materials, pre- and post-treatments, modifications, and applications of 3D-printed objects, especially for fused filament fabrication (FFF). Different examples of conductive and non-conductive bespoke filaments using renewable biopolymers, bioplasticizers, and recycled materials are presented and discussed. The main final characteristics of the polymeric materials achieved according to the feedstock, preparation, extrusion, and treatments are also covered. In addition to recycling and remanufacturing, this review also explores other alternative approaches that can be adopted to enhance the sustainability of methods, aiming to produce efficient and environmentally friendly 3D printed products. Adjusting printing parameters and miniaturizing systems are also highlighted in this regard. All these recommended strategies are employed to minimize environmental damage, while also enabling the production of high-quality, economical materials and 3D printed systems. These efforts align with the principles of Green Chemistry, Sustainable Development Goals (SDGs), 3Rs (Reduce, Reuse, Recycle), and Circular Economy concepts.
本综述旨在概述可持续方法，这些方法可纳入材料开发、3D打印物体的预处理和后处理、改性及应用的知名流程中，尤其是针对熔融长丝制造（FFF）。文中展示并讨论了使用可再生生物聚合物、生物增塑剂和回收材料的导电和非导电定制长丝的不同示例。还涵盖了根据原料、制备、挤出和处理所获得的聚合物材料的主要最终特性。除了回收和再制造外，本综述还探讨了可采用的其他替代方法，以提高方法的可持续性，旨在生产高效且环保的3D打印产品。在这方面，调整打印参数和使系统小型化也得到了强调。所有这些推荐策略都用于尽量减少环境破坏，同时还能生产高质量、经济的材料和3D打印系统。这些努力符合绿色化学原则、可持续发展目标（SDGs）、3R原则（减少、再利用、回收）和循环经济概念。
