3D printing is a powerful emerging technology for the tailored fabrication of advanced functional materials. This Review summarizes the state-of-the art with regard to 3D laser micro- and nanoprinting and explores the chemical challenges limiting its full exploitation: from the development of advanced functional materials for applications in cell biology and electronics to the chemical barriers that need to be overcome to enable fast writing velocities with resolution below the diffraction limit. We further explore chemical means to enable direct laser writing of multiple materials in one resist by highly wavelength selective (λ-orthogonal) photochemical processes. Finally, chemical processes to construct adaptive 3D written structures that are able to respond to external stimuli, such as light, heat, pH value, or specific molecules, are highlighted, and advanced concepts for degradable scaffolds are explored.
3D 打印是一种用于定制制造先进功能材料的强大新兴技术。这篇综述总结了 3D 激光微纳打印的最新技术进展，并探讨了限制其充分利用的化学挑战：从开发用于细胞生物学和电子学应用的先进功能材料，到需要克服的化学障碍，以实现低于衍射极限分辨率的高速写入速度。我们还进一步探讨了通过高度波长选择性（λ-正交）光化学反应，在一种抗蚀剂中直接激光写入多种材料的化学方法。最后，突出了构建能够对外界刺激（如光、热、pH 值或特定分子）做出响应的自适应 3D 写入结构的化学过程，并探讨了可降解支架的先进概念。
