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: 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 additive manufacturing system has a controller configured to operate an actuator to move a multi-nozzle extruder in an XY plane and rotate the multi-nozzle extruder about an axis perpendicular to the XY plane while operating the multi-nozzle extruder to form swaths in the XY plane. The controller operates the actuator and the multi-nozzle extruder to keep the nozzles of the extruder within perimeters formed for an object and to vary the speed and rotation of the extruder while extruding material to form precise structures.

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 process including providing a substantially flat printed image on a substrate; disposing a curable gellant composition onto the printed image in registration with the printed image, successively depositing additional amounts of the gellant composition to create a raised image in registration with the printed image; and curing the deposited raised image. A process including providing a printed image on a substrate; disposing a curable non-gellant composition onto the printed image in registration with the printed image; and disposing a curable gellant composition onto the printed image in registration with the printed image; to create a raised image in registration with the printed image; and curing the deposited raised image.
