This article explores a new open-source method for developing and manufacturing high-quality scientific equipment suitable for use in virtually any laboratory. A syringe pump was designed using freely available open-source computer aided design (CAD) software and manufactured using an open-source RepRap 3-D printer and readily available parts. The design, bill of materials and assembly instructions are globally available to anyone wishing to use them. Details are provided covering the use of the CAD software and the RepRap 3-D printer. The use of an open-source Rasberry Pi computer as a wireless control device is also illustrated. Performance of the syringe pump was assessed and the methods used for assessment are detailed. The cost of the entire system, including the controller and web-based control interface, is on the order of 5% or less than one would expect to pay for a commercial syringe pump having similar performance. The design should suit the needs of a given research activity requiring a syringe pump including carefully controlled dosing of reagents, pharmaceuticals, and delivery of viscous 3-D printer media among other applications.
本文探索了一种新的开源方法，用于开发和制造适用于几乎任何实验室的高质量科学设备。使用免费的开源计算机辅助设计（CAD）软件设计了一种注射泵，并使用开源的RepRap 3D打印机和现成的零件进行制造。设计、材料清单和组装说明可供任何希望使用它们的人在全球范围内获取。文中提供了有关CAD软件和RepRap 3D打印机使用的详细信息。还展示了如何使用开源的树莓派计算机作为无线控制设备。对注射泵的性能进行了评估，并详细介绍了评估方法。整个系统的成本，包括控制器和基于网络的控制界面，约为具有类似性能的商用注射泵预期价格的5%或更低。该设计应能满足特定研究活动对注射泵的需求，包括精确控制试剂、药物的剂量，以及输送粘性3D打印介质等其他应用。
