Abstract: A system for three-dimensional printing comprises an array of nozzles for dispensing building materials, a work tray (12/360) and a jig (402) configured for affixing a fabric (420) to the work tray. A computerized controller operates at least the array of nozzles to dispense a building material in a configured pattern corresponding to a shape of an object on the affixed fabric.

Abstract: A service station system for a three-dimensional printing system comprises: a bath, having a fast-release connector at a front side thereof, and a hinge at a back side thereof for hingebly connecting an open top of the bath to a surface of the three-dimensional printing system; and a wiper assembly, having a wiper device detachably connected to a wiper base mounted on a rotatable axis passing through the bath. The wiper device wipes a dispensing face of the printing head of the three-dimensional printing system while the head reciprocally moves above the bath between the back side and the front side. The service station system can also comprise a motor for rotating the axis.
