Abstract While the developments of additive manufacturing (AM) techniques have been remarkable thus far, they are still significantly limited by the range of printable, functional material systems that meet the requirements of a broad range of industries; including the health care, manufacturing, packaging, aerospace, and automotive industries. Furthermore, with the rising demand for sustainable developments, this review broadly gives the reader a good overview of existing AM techniques; with more focus on the extrusion-based technologies (fused deposition modeling and direct ink writing) due to their scalability, cost efficiency and wider range of material processability. It then goes on to identify the innovative materials and recent research activities that may support the sustainable development of extrusion-based techniques for functional and multifunctional (4D printing) part and product fabrication.

基于熔融沉积建模的增材制造（3D 打印）：聚合物材料系统技术

摘要 虽然迄今为止增材制造 (AM) 技术的发展令人瞩目，但它们仍然受到可满足广泛行业需求的可印刷功能材料系统范围的极大限制。包括医疗保健、制造、包装、航空航天和汽车行业。此外，随着对可持续发展的需求不断增长，这篇评论广泛地为读者提供了对现有 AM 技术的一个很好的概述；由于其可扩展性、成本效率和更广泛的材料可加工性，更多地关注基于挤出的技术（熔融沉积建模和直接墨水写入）。
