This project describes the procedure to repurpose a 3D Printer to a set of three syringe pumps. All the components, even the screws and the tools needed for the build are in the 3D printer box, simplifying the acquisition of each separate component. The only additional parts to be purchased are 5x5 shaft couplers, M5 nuts and M5 threaded rods, available at any hardware store. The 3D printed parts are supplied in their original CAD format (.F3D) as well as .STL files ready to be 3D printed. Printable parts were designed using Fusion 360 from Autodesk. For this specific project, we used a Creality Ender 3 3D printer, as it is one of the cheapest FDM on the market, and it is open source/open hardware . However, as all FDM 3D printers work by moving a XYZ stage, this method can be applied to any 3D printer by redesigning the 3D printed parts, while the G-code programming will remain the same. In fact, the programming of the pumps is also easy as it leverages the Marlin firmware already present on many 3D printer motherboards, and G-code files for controlling the pumps can be easily written as text files. This project comprises of an easy to assemble and program syringe pump set, which can be used for:
