  • Publication number: 20170182560
    Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a bulk metallic glass build material. By heating the bulk metallic glass at an elevated temperature in between an object and adjacent support structures, an interface layer can be interposed between the object and support where the bulk metallic glass becomes crystallized to create a more brittle interface that facilitates removal of the support structure from the object after fabrication.

  • Publication number: 20170173697
    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.

  • Publication number: 20170173878
    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.

  • Publication number: 20170173694
    Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a bulk metallic glass. A shearing engine within a feed path for the bulk metallic glass actively induces a shearing displacement of the bulk metallic glass to mitigate crystallization, more specifically to extend processing time for handling the bulk metallic glass at elevated temperatures.

  • Publication number: 20170173693
    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.

  • Publication number: 20170173692
    Abstract: In an aspect, a printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material. An ultrasonic vibrator is incorporated into the printer to improve the printing process, e.g., by disrupting a passivation layer on the deposited material to improve interlayer bonding, and to prevent adhesion of the metallic build material to a nozzle and other printer components.

  • Publication number: 20170173877
    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.

  • Publication number: 20170173879
    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.

  • Publication number: 20170173695
    Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material such as a bulk metallic glass. A thermal history of the object may be maintained, e.g., on a voxel-by-voxel basis in order to maintain a thermal budget throughout the object suitable for preserving the amorphous, uncrystallized state of the bulk metallic glass, and to provide a record for prospective use and analysis of the object.

  • Publication number: 20170056970
    Abstract: Thermal parameters for an additive manufacturing process are estimated using computer modeling, and these thermal parameters are used to control the additive manufacturing process. For example, the thermal parameters may be estimated based on bulk material properties, object geometry, control signals to thermal components of a system, and so forth.

  • Publication number: 20170056966
    Abstract: An additive manufacturing system uses electrohydrodynamic (EHD) printing techniques to form a metallic object based upon a digital model. A metal build material is melted within a reservoir and expelled through an outlet of an expeller in a controlled manner using EHD force to modulate surface tension on a meniscus of the liquid metal at the outlet of the expeller. Concurrently, a positioning robotics system moves the expeller relative to a print bed along a toolpath that forms the solidifying metal droplets into a net shape according to the digital model.

  • Publication number: 20170056967
    Abstract: A metallic electrohydrodynamic (EHD) three-dimensional printer fabricates an object while surface characteristics of the object are monitored. Sensors acquire data on surface characteristics, and feedback related to these surface characteristics is used to adjust the fabrication process, e.g., where the surface characteristics deviate from a target surface shape.

  • Patent number: 7571079
    Abstract: Processing data in a computer-aided design (CAD) system includes determining that a feature of a three-dimensional model has a condition that requires correction. The condition is automatically corrected by performing an action. The action may be an action that reorders a sequence of features in the three-dimensional model, an action that changes at least one parameter of the feature, an action that deletes a feature reference, or an action that changes a feature reference. Furthermore, the action may have one or more constraints that bound the action to a set of features that are directly and indirectly related to the feature on which the action operates.

  • Patent number: 7313504
    Abstract: Modeling of a three-dimensional object includes storing data representing a computer model of the three-dimensional object. The data includes a number of feature objects each of which defines a feature of the computer model. A feature chain is formed and includes at least one feature object having a design effect limited in scope such that an operation for removing material operates to affect the feature of the computer model defined by another feature object in the same feature chain and does not affect the feature of the computer model defined by the feature object not in said same feature chain. Multiple feature chains can be combined to form an interrelationship among feature objects that represents a hierarchy defining construction of the model from the feature objects.

  • Patent number: 6603486
    Abstract: Processing data objects of a two-dimensional drawing includes marking data objects corresponding to annotation, separating the drawing into a plurality of views, and associating each of the data objects corresponding to annotation with one of the views. Separating the drawing into a plurality of views may include constructing a plurality of intersection and proximity graphs and using the graphs to provide a plurality of connected sets, where each set may correspond to one of the views. The border views may be identified by determining which of the views include less than a predetermined number of elements, contain at least two other views, and are not contained in other views.
