数字光处理(DLP)3D打印已经成为快速制造复杂功能结构的强大制造工具。DLP 3D打印的快速发展与光学设计因素和油墨选择的研究有关。这篇批判性的综述强调了光聚合油墨的DLP 3D打印中的主要挑战。求解了DLP印刷机中光聚合反应的动力学方程，解释了固化深度与工艺光学参数和油墨化学性质的关系。综述了DLP平台设计和油墨选择方面的研究进展，并通过实验数据说明了单体结构和相对分子质量对印刷分辨率的影响。提出了一个详细的指导原则，以帮助工程师和科学家选择油墨和光学参数，以制造多材料和4D打印的功能结构。
Digital light processing (DLP) 3D printing has become a powerful manufacturing tool for the fast fabrication of complex functional structures. The rapid progress in DLP 3D printing has been linked to research on optical design factors and ink selection. This critical review highlights the main challenges in the DLP 3D printing of photopolymerizable inks. The kinetics equations of photopolymerization reaction in a DLP printer are solved, and the dependence of curing depth on the process optical parameters and ink chemical properties are explained. Developments in DLP platform design and ink selection are summarized, and the roles of monomer structure and molecular weight on printing resolution are shown by experimental data. A detailed guideline is presented to help engineers and scientists to select inks and optical parameters for fabricating functional structures for multi-material and 4D printing.
