Patent ID: 10471665

Abstract:
Embodiments provide a method for fabricating a three-dimensional (3D) object from a digital representation of the 3D object stored in a computer readable media, the method comprising relatively driving a nozzle with respect to a build platform, wherein the 3D object is being fabricated on the build platform and while relatively driving the nozzle with respect to the build platform, depositing, via the nozzle, printing material to fabricate a first sub-wall of the 3D object in a layer. The method further comprises while further relatively driving the nozzle with respect to the build platform, depositing, via the nozzle, printing material to fabricate a second sub-wall of the 3D object in the layer and adjacent to the first sub-wall. The second sub-wall is fabricated such that (i) the second sub-wall periodically contacts the first sub-wall and (ii) a void is periodically present between the second sub-wall and the first sub-wall.
