虚拟和打印的3D晶体模型都可以帮助学生和教师处理对称性和点群等化学教育主题。在本文中，两个免费下载的工具（交互式PDF文件和移动的应用程序）的应用程序的3D设计研究点对称的例子。还探索了使用3D打印来生产有形的晶体模型。一系列的解剖难题，这将是特别有用的教学晶体学的概念，如不对称单位和一般/特殊的位置。鼓励教育工作者在他们的课堂上使用所提供的工具，我们希望我们的工作能激励其他大学教育工作者设计和分享类似的工具。
Both, virtual and printed 3D crystal models can help students and teachers deal with chemical education topics such as symmetry and point groups. In the present paper, two freely downloadable tools (interactive PDF files and a mobile app) are presented as examples of the application of 3D design to study point-symmetry. The use of 3D printing to produce tangible crystal models is also explored. A series of dissection puzzles that will be especially useful for teaching crystallographic concepts such as asymmetric unit and general/special positions is presented. Educators are encouraged to use the presented tools in their classes, and we expect our work to inspire other college educators to design and share similar tools.
