    Abstract: Inkjet head cleaning and storage includes cleaning an orifice plate by inserting a tip of a shaped wiper into a slit of a printing mask, such that one or more shoulders of a handling end of the shaped wiper are in contact with respectively one or more edges of the slit. The shoulders of the shaped wiper facilitate the tip applying a predetermined pressure to an orifice surface during wiping. Preventing sediment buildup during extended periods of non-printing includes placing at least the orifice plate of the printing head in a protecting liquid that avoids evaporation of the volatile liquid from the nozzles. An innovative “night plate” can be used to seal the slit of a printing mask and ink purged from the printing head used to fill a gap between the printing head and the mask, thereby covering at least the orifice plate with purged ink.

    Abstract translation: 喷墨头清洁和储存包括通过将成形刮水器的尖端插入打印掩模的狭缝中来清洁孔板，使得成形刮水器的处理端的一个或多个肩部分别与一个或多个边缘接触 狭缝。 成形的刮水器的肩部有助于尖端在擦拭期间向孔表面施加预定的压力。 防止长时间非印刷期间的沉积物积聚包括将打印头的至少孔板放置在避免挥发性液体从喷嘴蒸发的保护液体中。 可以使用创新的“夜板”来密封印刷面具的狭缝和从用于填充打印头和面罩之间的间隙的打印头清除的墨水，从而至少用清洗的墨水覆盖孔板。

    Abstract: The present disclosure provides additive manufacturing apparatuses and maintenance methods. For example, in one embodiment an additive manufacturing apparatus is provided. The apparatus includes a reservoir configured to contain additive manufacturing material and a supply conduit for interconnecting the reservoir with a print head. The apparatus further includes a regulator configured to control pressure of additive manufacturing material in the print head to trigger purging of the print head and an air-ink separator configured to receive a mixture of air and purged additive manufacturing material. The air-ink separator is configured to reclaim at least a portion of the additive manufacturing material from the mixture. The apparatus may further include a return conduit interconnecting the air-ink separator with the reservoir for circulating back the reclaimed additive manufacturing material to the reservoir to enable the reclaimed additive manufacturing material to be utilized for manufacturing a three-dimensional object.
