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: 3D (three-dimensional) ink-jet printing includes techniques for evaporating a carrier liquid during printing while at least a portion of dispersant remains in the printed layer; evaporating dispersant in a first layer prior to sintering the first layer and/or prior to printing a second layer; leveling an upper-layer of a printed object using a horizontal roller; and printing layers of an object, each layer with both object and support portions, resulting in an object with support, in particular, support for negative angles and molds.
