Graphene and related 2D materials offer an ideal platform for next generation disruptive technologies and in particular the potential to produce printed electronic devices with low cost and high throughput. Interest in the use of 2D materials to create functional inks has exponentially increased in recent years with the development of new ink formulations linked with effective printing techniques, including screen, gravure, inkjet and extrusion-based printing towards low-cost device manufacturing. Exfoliated, solution-processed 2D materials formulated into inks permits additive patterning onto both rigid and conformable substrates for printed device design with high-speed, large-scale and cost-effective manufacturing. Each printing technique has some sort of clear advantages over others that requires characteristic ink formulations according to their individual operational principles. Among them, the extrusion-based 3D printing technique has attracted heightened interest due to its ability to create three-dimensional (3D) architectures with increased surface area facilitating the design of a new generation of 3D devices suitable for a wide variety of applications. There still remain several challenges in the development of 2D material ink technologies for extrusion printing which must be resolved prior to their translation into large-scale device production. This comprehensive review presents the current progress on ink formulations with 2D materials and their broad practical applications for printed energy storage devices and sensors. Finally, an outline of the challenges and outlook for extrusion-based 3D printing inks and their place in the future printed devices ecosystem is presented.
石墨烯及相关二维材料为下一代颠覆性技术提供了理想平台，尤其具有制造低成本、高通量印刷电子器件的潜力。近年来，随着与有效印刷技术相关的新型油墨配方的发展，包括丝网印刷、凹版印刷、喷墨印刷和挤出式印刷等面向低成本器件制造的技术，使用二维材料制造功能性油墨的兴趣呈指数级增长。将剥离的、溶液处理的二维材料配制成油墨，可在刚性和柔性基板上进行添加式图案化，以实现高速、大规模且经济高效制造的印刷器件设计。每种印刷技术相对于其他技术都有某种明显优势，这需要根据其各自的操作原理采用特定的油墨配方。其中，挤出式3D打印技术因其能够创建具有更大表面积的三维（3D）结构而备受关注，这有利于设计适用于各种应用的新一代3D器件。在将二维材料油墨技术用于挤出印刷的开发过程中，仍存在若干挑战，在将其转化为大规模器件生产之前必须加以解决。这篇全面的综述介绍了含二维材料的油墨配方目前取得的进展及其在印刷储能器件和传感器方面的广泛实际应用。最后，概述了挤出式3D打印油墨面临的挑战和前景，以及它们在未来印刷器件生态系统中的地位。
