3D Printing of an Electrolyzer and its Validation for School Educational Purposes

This study introduces the design, 3D printing, and validation of the functionality of a low-cost electrolyzer intended for teaching chemistry in primary and secondary schools. The electrolyzer was designed in SolidWorks and printed from polylactic acid filament on a Prusa MK3S printer. The assembled device was tested in a series of electrolytic experiments with solutions of sodium chloride, copper sulfate, and lead acetate. The results confirmed the functionality of the electrolyzer and its didactic potential in demonstrating redox processes. The production is technically feasible even in a school environment and allows for further modifications of the model. In addition to understanding electrochemical principles, the project also supports the development of interdisciplinary skills, creativity, and student engagement by integrating digital technologies into science teaching. The device proved to be reliable and safe for school use with minimal material and equipment requirements. Possible limitations regarding tightness and material resistance are also discussed.
