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.

Service station for a three-dimensional printing system

Methods of printing a 3D object comprising depositing a building material, layer by layer, via printing heads comprising one or more nozzle arrays; and activating each of said printing heads to dispense a building material at least once within a specified period of time during printing to form a portion of said bulk region according to data provided by a CAD file, and activating said printing heads to deposit the building material to form another portion of the bulk region without relating to said data.

Waste cartridge

A method of additive manufacturing of a three-dimensional object, comprises: sequentially dispensing and solidifying layers to form on a surface a sacrificial structure. In embodiments the sacrificial structure comprises a bulk volume and heating cells embedded in the bulk volume, where the heating cells release more heat than the bulk volume upon the solidification of the layers. In embodiments, the sacrificial structure comprises pinning structures embedded in the bulk volume. The method also comprises sequentially dispensing and solidifying layers to form the three-dimensional object on a portion of the sacrificial structure.
