Three-dimensional printing, or additive manufacturing (AM), is a broad term for a wide range of fabrication methods utilizing materials such as small-molecule, polymer, and metal feedstocks. Each method requires different chemical, physical, and engineering needs to be successful. This article will discuss some of the considerations for polymer-based AM methods. Ultimately, we focus on the chemistries of vat photopolymerization, in which light is used to cure a resin from liquid to solid, to provide an example of how chemical advancements have led to increased speed, resolution, and multimaterial printing capabilities not previously possible.
三维打印，即增材制造（AM），是一个广泛的术语，涵盖了多种利用小分子、聚合物和金属原料等材料的制造方法。每种方法都需要不同的化学、物理和工程条件才能成功。本文将讨论基于聚合物的增材制造方法的一些注意事项。最终，我们将重点关注光固化聚合的化学原理，即利用光将树脂从液体固化为固体，以此为例说明化学进步是如何实现以前无法达到的速度提升、分辨率提高以及多材料打印能力的。
