Abstract: An actuation method comprising applying a force to a first rod of build material disposed within an actuation volume. The first rod of build material may include at least one metal. The method may further comprise moving the first rod of build material in a direction substantially parallel to or substantially coaxial with a longitudinal axis of the first rod of build material toward an extrusion head and loading a second rod of build material into the actuation volume. The second rod of build material may include at least one metal. A longitudinal axis of the second rod may be substantially coaxial with the longitudinal axis of the first rod. The applying step and the moving step may be repeated for the second rod of build material.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process. The exit of the nozzle may include a number of concentric rings, where each of which may be selectively opened or closed during extrusion to control extrusion properties such as a volume of extrudate or a mixture of material exiting the nozzle.

Abstract: Embodiments of the present disclosure are drawn to systems and methods for adjusting a three-dimensional (3D) model used in metal additive manufacturing to maintain dimensional accuracy and repeatability of a fabricated 3D part. These embodiments may be used to reduce or remove geometric distortions in the fabricated 3D part. One exemplary method may include: receiving, via one or more processors, a selection made by a user; receiving a 3D model of a desired part; retrieving at least one model constant based on the user's selection; receiving an input of at least one process variable setting from a set of process variable settings; generating transformation factors based on the at least one process variable parameter and the at least one model constant; transforming the 3D model of the desired part based on the transformation factors; and generating processing instructions for fabricating the transformed 3D model of the desired part.

Abstract: Methods of printing an object via a 3-dimensional printer include provide for printed objects having a higher density. A printer head is operated to deposit build material in lines under controlled parameters including lateral position, height, extrustion rate, extrusion temperature, and/or extrusion material. The printer may print first lines forming channels at a given layer, and then second lines to fill those channels. The printer may operate with other approaches to fill gaps between printed lines, such as offset and/or smaller lines aligned with those gaps. The resulting object has greater density while maintaining an accurate object shape.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process. The shape of an extrusion nozzle may be varied during extrusion to control, e.g., an amount of build material deposited, a shape of extrudate exiting the nozzle, a feature resolution, and the like.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a bulk metallic glass build material. By using thermally mismatched bulk metallic glasses for an object and adjacent support structures, the interface layer between these structures can be melted and crystallized to create a more brittle interface that facilitates removal of the support structure from the object after fabrication.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material. Joule heating is applied to an interface between adjacent layers of the object by creating an electrical circuit across the interface and applying pulsed current sufficient to join the metallic build material across the adjacent layers.

Abstract: A camera assembly is employed in additive manufacturing to improve the fidelity of a printed object. The camera may scan the surface of a build plate of a 3D printer and an object as it is being printed to generate image data. The image data is processed to detect errors in the build plate or printed object. The printer compensates for the detected errors, which can including modifying the printer configuration and/or modifying the instructions for printing a given object. Using the updated configuration, subsequent objects may then be printed, under a corrected process, to produce an object with fidelity to an original object model.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material. A build plate that receives the object during fabrication includes a coating of material with a low melt temperature, such as a low melt temperature solder. In particular, the material may be an alloy that can be solidified while receiving the object, and then heated into a liquid state to facilitate removal of the object after fabrication is complete at a temperature sufficiently low that the adjacent, fabricated object does not melt or deform.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process. A former extending from a nozzle of the printer supplements a layer fusion process by applying a normal force on new material as it is deposited to form the object. The former may use a variety of techniques such as heat and rolling to improve physical bonding between layers.
