There has been much research in recent years aiming to make scientific instrumentation more accessible. An increase in accessibility has many benefits including reduced costs and expanded opportunities to learn about instrumentation. 3D printing of scientific instrumentation provides an option that is cheap and customizable. This study follows the development of a 3D-printed ball check valve to be implemented in a reciprocating pump such as one used for high performance liquid chromatography (HPLC). The valve was designed using OpenSCAD and printed using a Prusa i3 MK2S 3D printer. Ball check valves with both a spherical and conical design were designed, and early qualitative tests point towards the conical design being desirable. Future work includes the design of a reciprocating piston, the implementation of the piston along with two check valves to create a complete reciprocating pump, and quantifying pressures achieved by the pump.
