Abstract: An additive manufacturing system opens the valves in an extruder needed to form a swath and operates an actuator to move the extruder through a transition region with those valves open to establish an amount of extrusion material between a faceplate of the extruder and a portion of an object being formed that is adequate for formation of a swath. The length of the transition region is determined with reference to a viscosity of the material being extruded and a speed at which the extruder is moved to form the swath. The transition region can be perpendicular to a path of the extruder to form the swath or aligned with the path of the extruder to form the swath.

Abstract: An additive manufacturing system operates an actuator to move an extruder with reference to a selected first zig-zag pattern to sparsely fill an interior region of an object by extruding a swath of thermoplastic material that has straight portions connected by angled portions. After a first pass using the first zig-zag pattern is completed, a second zig-zag pattern is used to form a complementary swath that forms rigid structure with the first swath. Use of the two patterns is alternated to sparsely fill the interior region in multiple layers of the object until a predetermined distance from a solid fill structure or surface is detected. Transition patterns are then used to increase the density of the swaths in the interior region in the next successive layers of the object until the layer is reached where a solid fill surface is formed over the swaths formed using the transition patterns.

Abstract: An additive manufacturing system has a controller configured to modify numerical control programming instructions to form interlocking structures that improve object structural integrity in the Z-direction. The interlocking structures are produced by forming one layer with swaths that are separated by gaps and another layer that is formed over the gaps to fill the gaps and lay over the swaths forming the gaps.

Abstract: A method of operating a multi-nozzle extruder in an additive manufacturing system enables support structure to be formed while an object is also being formed. The method includes opening more than one nozzle in the multi-nozzle extruder, and operating an actuator with a controller to move the multi-nozzle extruder along a path to form a first group of multiple parallel ribbons of support structure simultaneously with material extruded from the more than one open nozzle.

Abstract: An apparatus for distributing a hydrophobic material in a substrate includes a first roller, second roller that engages the first roller to form a nip, a heater operatively connected to the first roller and configured to heat the first roller to a first temperature that is greater than a second temperature of the second roller, and a substrate transport configured to move a substrate through the nip at a predetermined velocity. The first roller engages a first side of the substrate and the second roller engages a second side of the substrate to enable the hydrophobic material to penetrate into the substrate.
