Supplementary Information Files for An open source toolkit for 3D printed fluidics

Supplementary Information Files for An open source toolkit for 3D printed fluidics<br>As 3D printing technologies become more accessible, chemists are beginning to design and develop their own bespoke printable devices particularly applied to the field of flow chemistry. Designing functional flow components can often be a lengthy and laborious process requiring complex 3D modelling and multiple design iterations. In this work, we present an easy to follow design workflow for minimising the complexity of this design optimization process. The workflow follows the development of a 3D printable ‘toolkit’ of common fittings and connectors required for constructing basic flow chemistry configurations. The toolkit components consist of male threaded nuts, junction connectors and a Luer adapter. The files have themselves been made freely available and open source. The low cost associated with the toolkit may encourage educators to incorporate flow chemistry practical work into their syllabus such that students may be introduced to the principles of flow chemistry earlier on in their education and furthermore, may develop an early appreciation of the benefits of 3D printing in scientific research. In addition to the printable toolkit, the use of the 3D modelling platform – Rhino3D has been demonstrated for its application in fluidic reactor chip design modification. The simple user interface of the programme reduces the complexity and workload involved in printable fluidic reactor design.<br>

本文件为《3D打印流体器件开源工具包》的补充信息文件。
随着3D打印技术愈发普及，化学家们开始设计并开发定制化可打印器件，尤其应用于流动化学领域。设计功能性流动组件往往是一个冗长且费力的过程，需要复杂的三维建模与多轮设计迭代。
在本研究中，我们提出一套易于遵循的设计流程，以简化该设计优化过程的复杂度。该流程依托一套可3D打印的“工具包”开发而成，该工具包包含构建基础流动化学配置所需的常用配件与连接器。
工具包组件包括外螺纹螺母、连接接头以及鲁尔适配器（Luer adapter）。相关文件已完全免费开源。
该工具包成本低廉，可助力教育工作者将流动化学实操课程纳入教学大纲，使学生能够在学习早期接触流动化学原理，进而更早地领会3D打印在科学研究中的优势。
除可打印工具包外，本研究还演示了如何将三维建模平台Rhino3D应用于流体反应器芯片的设计修改。该软件简洁的用户界面可降低可打印流体反应器设计的复杂度与工作量。
