有形模型帮助学生和研究人员在三维（3D）中可视化化学结构。3D打印提供了一种独特而直接的方法来制造分子和扩展固体的塑料3D模型。在本文中，我们准备了一系列分子结构的数字三维设计文件，这些文件将有助于化学教育主题，如对称和点群的教学。本文讨论了两种主要的文件制备方法，概述了如何制备3D可打印的化学结构。这两种方法都从晶体学信息文件（.cif）或蛋白质数据库（.pdb）文件开始，并通过使用各种商业和免费软件最终转换为3D立体光刻（.stl）文件。从制备的一系列数字三维化学结构中，得到18个分子和7个扩展固体。3 d印制。我们的研究结果表明，本文讨论的文件制备方法都是制备可3D打印的化学结构数字文件的合适途径。此外，我们的研究结果还表明，3D打印是制造分子和扩展固体3D模型的绝佳方法。
Tangible models help students and researchers visualize chemical structures in three dimensions (3D). 3D printing offers a unique and straightforward approach to fabricate plastic 3D models of molecules and extended solids. In this article, we prepared a series of digital 3D design files of molecular structures that will be useful for teaching chemical education topics such as symmetry and point groups. Two main file preparation methods are discussed within this article that outlines how to prepare 3D printable chemical structures. Both methods start with either a crystallographic information file (.cif) or a protein databank (.pdb) file and are ultimately converted into a 3D stereolithography (.stl) file by using a variety of commercially and freely available software. From the series of digital 3D chemical structures prepared, 18 molecules and 7 extended solids were. 3D printed. Our results show that the file preparation methods discussed within this article are both suitable routes to prepare 3D printable digital files of chemical structures. Further, our results also suggest that 3D printing is an excellent method for fabricating 3D models of molecules and extended solids.
