Plasma technology and rapid prototyping are two emerging technologies, each with its own set of benefits. However, the benefits of these technologies are rarely combined. The discharge chamber of Dielectric Barrier Discharge (DBD) reactors for investigating CO2 utilization were created using a 3D printer in this study. Because of rapid prototyping's high adaptability and modification potential, the results of fluid dynamics simulations can be directly introduced in the plasma reactor manufacturing process. DBD reactors are made of methacrylic acid polymer and have an overall dimension of 120 x 120 mm, with a powered electrode size of 55 x 55 mm in the center. 3D-printed reactors were initially tested with three different feed-gases: synthetic air, nitrogen, and carbon dioxide to ensure that stable plasma could be generated. Based on electrical characterization, in particular voltage-charge plots, operation parameters such as applied voltage, plasma power, and effective capacitance were studied in detail. Three DBD reactors with different gas flow distribution and velocity profiles were then investigated for carbon monoxide formation in pure CO2. In future experiments, the production of value-added chemicals such as CO and methanol will be further studied.
