1. A system for additive manufacturing of a three-dimensional object, the system comprising:
a working surface;
a first dispensing head configured to dispense a first building material by inkjet technology;
a second dispensing head configured to dispense a second building material by a technology other than said inkjet technology; and
a controller configured for establishing a relative motion between said working surface and said dispensing heads, and for controlling said dispensing heads to dispense building materials during said relative motion so as to form a plurality of layers, each patterned according to the shape of a cross section of the object;
wherein said controller is configured for establishing said relative motion in a manner that said dispensed first building material forms a raster pattern within a layer and said dispensed second building material forms a vector pattern within said layer.
