Abstract: A printing device for dispending material on a heated substrate is provided. The device may include a printing head having one or more nozzles and a heat shield that partially masks a side of the printing head that faces the heated substrate when printing so as to reduce heat transfer from the substrate to the printing head. The shield includes a slot aligned with the one or more nozzles to enable passage of material from the one or more nozzles to the heated substrate.

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: 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.
