Three-Dimensional Printer Head Including a Dielectric Barrier Discharge (DBD) Disk and a Transformer Assembly
20230102328 · 2023-03-30 ·

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.

MANIFOLD AND RELATED METHODS FOR USE WITH A RESERVOIR FOR ADDITIVE MANUFACTURING

The presently disclosed embodiments generally relate to reservoir manifold systems suitable for use with an additive manufacturing apparatus. Such manifold systems enable ease of use for making mechanical, electrical, and fluid connections to a reservoir used for additive manufacturing. Conduits formed in the reservoir manifold can allow for a fluid connection to be established with a reservoir to allow fluid flow into and out of the reservoir. The reservoir manifold can include one or more arms that are configured to move independently to couple to the reservoir of the printing apparatus. The reservoir manifold can include a trigger coupled to a latch mechanism for engaging one or more components of the apparatus. In some embodiments, the ability of the manifold to make electrical connections to the reservoir may present advantages to the ease-of-use and reliability of an additive manufacturing apparatus.
