抽象的

添加 itive manufacturing (3D printing) is a technology with near-unlimited potential for the chemical educator. However, its adoption into higher education has been limited by the dual requirements of expertise in 3D printing and 3D computer-aided design (CAD). Thus, its reported utilization in the chemistry curriculum has been within the creation of 3D models for the macroscopic visualization of molecular models and processes. With the commercialization of inexpensive 3D printers, we seek to provide a series of optical mounts and tools for use in chemical research or education by designing systems which may be mounted on a breadboard and used to construct chemical instrumentation. These designs include mounts for cylindrical lenses or mirrors with 0.5, 1, and 2 in. diameters, 0.5 in. diffraction gratings, an adjustable optical slit, cuvette holders, stepper motor (NEMA 17) adapters, and a modular, 3D printed breadboard. All designs were created using Solidworks CAD, and have been provided in Supporting Information and uploaded to //github.com/EdavisAPU/Education-Optics in both Solidworks native format (.sldprt)和3D对象的标准文件交换格式(.stl)使用,修改或协作的格式。所有文件都在MIT开源许可证下发布(修改设计)。与商业上可获得的产品相比,本文所呈现的原型提供了显着的成本节约,许多设计比商业等价物更便宜1-2个幅度。此外,随着学生设计和构造了使用这些光学器件的可见分光光度计,这些设计已经在上层仪器分析课程中使用。来自所得仪器的数据并与市售的分光光度计进行比较。
