Digital light processing (DLP) 3D printing is rapidly advancing and has emerged as a powerful additive manufacturing approach to fabricate analytical microdevices. DLP 3D-printing utilizes a digital micromirror device to direct the projected light and photopolymerize a liquid resin, in a layer-by-layer approach. Advances in vat and lift design, projector technology, and resin composition, allow accurate fabrication of microchannel structures as small as 18 × 20 µm. This review describes the latest advances in DLP 3D-printing technology with respect to instrument set-up and resin formulation and highlights key efforts to fabricate microdevices targeting emerging (bio-)analytical chemistry applications, including colorimetric assays, extraction, and separation.
数字光处理（DLP）3D打印技术正在迅速发展，并已成为一种强大的增材制造方法，用于制造分析微器件。DLP 3D打印利用数字微镜器件来引导投射光，并以逐层方式使液体树脂光聚合。在光固化槽和升降设计、投影仪技术以及树脂成分方面的进展，使得能够精确制造小至18×20微米的微通道结构。本文综述了DLP 3D打印技术在仪器设置和树脂配方方面的最新进展，并重点介绍了针对新兴（生物）分析化学应用制造微器件的关键成果，包括比色测定、萃取和分离。
