In this paper, a teaching approach for the comprehension of the symmetry properties of an aperiodic crystal structure was described. Building a continuous-fill (quasi)crystalline pattern with the support of 3D-printed Penrose tiles, students can grasp the lack of translational symmetry typical of an aperiodic crystal.

准周期性晶体：带有3D打印Penrose磁贴的晶体晶格的非周期性

本文介绍了一种理解非周期性晶体结构对称性的教学方法。在3D打印的Penrose瓷砖的支持下构建连续填充的（准）晶体图案，学生可以了解缺乏非周期性晶体典型的平移对称性的问题。
