3D打印可以改变现有的生产方法,是第四次工程革命中的一项现代技术.它从成型原理上提出了分层制造、逐层叠加成型的新颖生产方法,从根本上简化了制造工艺,实现了大规模定制生产.然而,这一新技术仍存在许多问题.除了纯石墨烯外,sp2碳具有好的亲水性,3D打印难度较小.sp2碳还可在3D打印中的各种阶段应用.纯石墨烯的疏水性使其难以在水系介质中打印和加工.毛细管油墨的发展使得纯石墨烯的3D打印成为可能.本文综述了 sp2碳的3D打印技术的最新进展.首先简要概述了 3D打印技术,随后概述了 sp2碳的3D打印及其在各种方面的应用.最后,讨论了这一新领域的发展前景和机遇.
Three dimensional(3D)printing is a modern technology that has the possibility to transform existing production meth-ods.It offers a novel production method of layered manufacturing and layer-by-layer stacking,which radically simplifies the manu-facturing process and enables large-scale customizable production.However,there are still numerous problems with this new techno-logy.Except for pure graphene,sp2 carbons can be 3D printed with little difficulty because of their hydrophilicity.The hydrophobic nature of pure graphene makes it difficult to print and process in water-based media,but advances in capillary inks allow for the 3D printing of pure graphene.This review focuses on the most recent developments in the 3D printing of sp2 carbons.A concise over-view of 3D printing technologies is presented,followed by a summary of 3D printed sp2 carbons and their diverse applications.Fi-nally,prospects and opportunities for this new field are discussed.
