摘要
本综述旨在概述可持续方法,这些方法可纳入众所周知的三维打印对象(尤其是熔融长丝制造(FFF))的材料开发、前后处理、修改和应用程序。本文介绍并讨论了使用可再生生物聚合物、生物增塑剂和回收材料定制导电和非导电长丝的不同实例。此外,还介绍了根据原料、制备、挤压和处理实现的聚合物材料的主要最终特性。除回收和再制造外,本综述还探讨了其他可采用的替代方法,以提高方法的可持续性,从而生产出高效、环保的 3D 打印产品。调整打印参数和系统小型化也是这方面的重点。所有这些建议的策略都是为了最大限度地减少对环境的破坏,同时还能生产出优质、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(减少、再利用、再循环)和循环经济概念。
How to Improve Sustainability in Fused Filament Fabrication (3D Printing) Research?
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.
