Introductory chemistry students encounter the concept of hybrid orbitals as a transition from atomic orbitals to molecular bonding. The principal purpose of learning hybridization in the undergraduate curriculum is to impart an understanding of the origins of molecular bonding and geometry. Physical models of both individual hybrid orbitals and combinations of hybrid orbital types have the potential to aid in student visualization of molecular geometry. 3D printing can serve to generate physically accurate models in a cost-effective manner. The use of a freely available JavaScript applet (CalcPlot3D) enables the generation of 3D-printing files (.stl/.3mf files) that can be subsequently printed on a 3D printer. The procedure is low-cost and relatively flexible and produces mathematically accurate hybrid orbital models that can serve as hands-on pedagogical tools.

动手杂交：混合轨道的3D打印模型

入门化学专业的学生会遇到混合轨道的概念，这是从原子轨道到分子键的过渡。在本科课程中学习杂交的主要目的是赋予对分子键合和几何学起源的理解。单个混合轨道和混合轨道类型组合的物理模型都有可能帮助学生可视化分子几何形状。3D打印可用于以经济高效的方式生成物理上准确的模型。使用免费的JavaScript小程序（CalcPlot3D）可以生成3D打印文件（.stl / .3mf文件），然后可以在3D打印机上进行打印。
