Natural fiber composites attract attention owing to their environmentally friendly attributes. Many techniques, including fiber treatment, coatings, and fiber orientations, are used to improve the strength of natural fiber-reinforced composites. Still, the strength needs to be improved as expected. At present, some automation in manufacturing is also supported. Recently, additive manufacturing (AM) of natural fiber-reinforced composites has attracted many researchers around the globe. In this work, researchers' attention to various natural fibers that are 3D printed is articulated and consolidated, and the future scope of the additive manufacturing of natural fiber-reinforced composite is envisaged using the patent landscape. In addition, some of the advancements in additive manufacturing of natural fiber composites are also discussed with reference to the patents filed lately. This may be helpful for the researchers working on AM of natural fiber composites for taking their research into new orientations.
天然纤维复合材料因其环保特性而备受关注。许多技术，包括纤维处理、涂层和纤维取向，都被用于提高天然纤维增强复合材料的强度。然而，强度仍需按预期提高。目前，制造过程中的一些自动化也得到了支持。最近，天然纤维增强复合材料的增材制造（AM）吸引了全球众多研究人员。在这项工作中，阐述并整合了研究人员对各种3D打印天然纤维的关注，并利用专利态势设想了天然纤维增强复合材料增材制造的未来发展前景。此外，还参照最近提交的专利讨论了天然纤维复合材料增材制造的一些进展。这可能有助于从事天然纤维复合材料增材制造的研究人员将他们的研究转向新的方向。
