Abstract: The present teachings relate to various embodiments of a gas enclosure system that can have various components comprising a particle control system that can provide a low-particle zone proximal to a substrate. Various components of a particle control system can include a gas circulation and filtration system, a low-particle-generating motion system for moving a printhead assembly relative to a substrate, a service bundle housing exhaust system, and a printhead assembly exhaust system. In addition to maintaining substantially low levels for each species of various reactive species, including various reactive atmospheric gases, such as water vapor and oxygen, for various embodiments of a gas enclosure system that have a particle control system, an on-substrate particle specification can be readily met. Accordingly, processing of various substrates in an inert, low-particle gas environment according to systems and methods of the present teachings can have substantially lower manufacturing defects.

Abstract: The present teachings disclose various embodiments of a printing system for printing a substrate, in which the printing system can be housed in a gas enclosure, where the environment within the enclosure can be maintained as a controlled printing environment. A controlled environment of the present teachings can include control of the type of gas environment within the gas enclosure, the size and level particulate matter within the enclosure, control of the temperature within the enclosure and control of lighting. Various embodiments of a printing system of the present teachings can include a bulk ink delivery system that can be external to a gas enclosure. A bulk ink delivery system according to the present teachings can supply ink to a local ink delivery system that is internal to the gas enclosure. Various embodiments of a local ink delivery system of the present teachings can be proximal to a printhead device assembly, and can include a two-stage ink supply having a local ink replenishment reservoir that is configured to supply a local ink dispensing reservoir to a constant volume. According to the present teachings, a local ink dispensing reservoir can be in flow communication with a plurality of printhead devices. As such, a two-stage local ink delivery system maintaining a constant volume in a local ink dispensing reservoir can provide constant head pressure to the plurality of printhead devices.
