Patent abstract
A method and apparatus for manufacturing of 3D objects. The apparatus includes a number of material deposition heads terminated by nozzles, of which one or two nozzles are configured to deposit a first material to form a first and second pattern layers. The pattern layers are laterally shifted from each other such that when the first and second pattern layers are deposited, a space (empty volume) with a varying cross section is formed. In some examples, two or more nozzles could be used to deposit the corresponding first and second pattern layers. The nozzles could move independent of each other.
