Ender3 3D printer kit transformed into open, programmable syringe pump set

A cheap, open source 3D printer (Creality Ender 3) is transformed into an Open Hardware, programmable syringe pump set. Only 3 parts need to be purchased outside of the printer kit. All other parts are either in the Ender 3 kit, or can be 3D printed. No prior knowledge in electronics or programming languages is required. The pumps are controlled by the 3D printer firmware and motherboard and programmed in simple G-code text files. The total cost of a three pumps setup is -(sic)170. The pumps are capable of reaching stable flows down to 5 mL/min using cheap, disposable 10 mL syringes. Higher flow speeds are also achievable, in the order of mL/min. (C) 2021 The Author(s).

Automated summary

By transforming a cheap open source 3D printer into a programmable syringe pump set, with only 3 additional parts needed, stable flows can be achieved without prior knowledge in electronics or programming. The total cost is relatively low, and using cheap disposable syringes allows for different flow rates to be achieved.
