摘要： A three-dimensional object printer includes a controller that operates at least one ejector to place a layer of photopolymer material on a substrate. The controller is configured to cure the ejected photopolymer layer partially and position fiber on the cured layer before continuing to eject photopolymer material onto the fibers. The fibers can be loose or organized into a mesh. The pieces of mesh position on a cured layer can be pre-cut or a cutting device can be operated to cut pieces of mesh having a shape that corresponds to the shape of the layer of photopolymer material. The fibers reinforce the layers of photopolymer material and add strength and durability to the overall part being formed with the photopolymer material.

摘要： An additive manufacturing system includes a slip clutch coupled to an actuator of a mechanical driver that feeds solid extrusion material into a heater for supplying thermoplastic material to a manifold in an extruder head. A speed of the actuator can be set to enable the actuator to operate at a rotational speed that is slightly greater than the rotational speed of the mechanical mover. This configuration enables the pressure of the thermoplastic material in the manifold of the extruder head to be in a predetermined range no matter how many nozzles are opened in the extruder head.

摘要： A three-dimensional object printer uses stereolithography to form a structure and then embed one or more objects in the structure. The printer includes a controller that operates a source of ultraviolet (UV) radiation to cure a portion of a liquid photopolymer at an interface between the liquid photopolymer and the external surface of an embedded object with reference to a meniscus formed between the liquid photopolymer and the external surface of an embedded object. The incorporation of the embedded object speeds formation of the final object and increases the durability of the final object.

摘要： A three-dimensional object printing system improves the interlayer adhesion of an object. The printing system includes a platform on which a three-dimensional object is built. A material applicator in the printing system expels material to form layers of the object on the platform. The material applicator also includes a heater configured to heat the layer of the object ahead of the material applicator when the material applicator moves in a first direction and a second direction, both directions being parallel to the platform.

摘要： A multi-nozzle extrusion printhead includes a chamber with an inlet to receive an extrusion material and a plurality of outlets fluidly coupled to the chamber. The printhead also includes a plurality of valves that control flow of extrusion material through the fluid outlets to nozzles in the printhead. Each valve includes a member and an electromechanical actuator configured to move the member to a first position to block a flow of the extrusion material through one of the fluid outlets and nozzles and to a second position to enable the flow of the extrusion material through the fluid outlet and nozzles.

摘要： A three-dimensional object printing system improves the interlayer adhesion of an object. The printing system includes a platform on which a three-dimensional object is built. A material applicator in the printing system expels material to form layers of the object on the platform. The material applicator also includes a heater mounted to an arm that is configured to rotate about the material applicator to position the heater so the heater heats the layer of the object ahead of the material applicator as the material applicator moves relative to the platform.

摘要： A method of operating a multi-nozzle extrusion printhead includes operating with a controller a first actuator to produce relative movement between the printhead and an image receiving surface along a predetermined path for one layer of a three-dimensional printed object. The method further includes first printing an outline of a given layer and then printing the interior of the given layer using a plurality of extrusion nozzles. The method further optionally includes extruding material through a portion of the plurality of nozzles and turning on or off individual nozzles to ensure the swaths printed in the interior conform to the profile of the outline.

摘要： A printer is configured with at least two printheads that are separated from one another in a cross-process direction by an integral multiple of printhead widths. This configuration enables parallel swaths of material to be ejected and then movement of the printheads in the cross-process direction by a distance corresponding to one or more integral numbers of the printhead width enables the area between the swaths to be completed and the area outside of the original swaths printed.

摘要： A printhead including a plurality of actuators, wherein each actuator of the plurality of actuators includes a plurality of drive electrodes, a plurality of diaphragms, and a single nozzle. Each drive electrode is uniquely paired with one of the diaphragms. In an embodiment, the printhead may be configured so that all drive electrodes for a single actuator always activate simultaneously to eject ink from the single nozzle. In another embodiment, the printhead may be configured so that each drive electrode of the plurality of drive electrodes for a single actuator are individually addressable and may be fired independently of the other drive electrodes of the single actuator.
