Abstract
A printer head for a three-dimensional printer includes a dielectric barrier discharge (DBD) disk configured to generate a plasma, where the DBD disk requires a high voltage alternating current (AC) voltage signal to generate the plasma. The printer head also includes a transformer assembly including a transformer and a housing that contains the transformer. The transformer is configured to transform an incoming AC voltage signal into the high voltage AC signal for the DBD disk. The printer head also includes an electrical wire that electrically connects the transformer to the DBD disk. The printer head also includes a wire guide defining a passageway, where a portion of the electrical wire is received by the passageway in the wire guide. The passageway of the wire guide is shaped to direct the electrical wire towards the DBD disk.
