Additive manufacturing, normally referred to as three-dimensional (3D) printing, has been maturing rapidly in recent years and widely utilized in various industrial fields, because it can create predesigned functional products with sophisticated structures that are basically difficult to achieve using traditional methods. Among all 3D printing technologies, vat photopolymerization has attracted much attention because of its outstanding advantages such as fast printing speed, high precision, and ease of formulating. In recent years, many breakthroughs in photopolymerization based 3D printing have been achieved by photoreaction design regarding photopolymerizable monomers, photoinitiating systems, inhibition functions, light sourcs, etc., but challenges remain. This Perspective attempts to highlight these great advances regarding the promotion of printing efficiency, accuracy, and sustainability. At the end, several challenges, such as longer-wavelength printing, printing of functional materials, and multimaterial printing, are discussed, which must be carefully addressed to meet the increasing requirements of future high-performance additive manufacturing.
增材制造，通常被称为三维（3D）打印，近年来发展迅速并在各个工业领域得到广泛应用，因为它能够制造出具有复杂结构的预先设计的功能产品，而这些结构使用传统方法基本上难以实现。在所有3D打印技术中，光固化3D打印因其打印速度快、精度高和易于配方设计等突出优点而备受关注。近年来，通过对可光聚合单体、光引发体系、抑制功能、光源等进行光化学反应设计，基于光聚合的3D打印取得了许多突破，但挑战依然存在。本观点文章旨在突出这些在提高打印效率、精度和可持续性方面的重大进展。最后，讨论了几个挑战，如长波长打印、功能材料打印和多材料打印等，必须认真应对这些挑战以满足未来高性能增材制造不断增长的需求。
