  • REMOVABLE SUPPORT STRUCTURE WITH AN INTERFACE FORMED BY CRYSTALLIZATION OF BULK METALLIC GLASS
    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.

  • FUSED FILAMENT FABRICATION EXTRUSION NOZZLE WITH CONCENTRIC RINGS
    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.

  • METAL PRINTER WITH VIBRATING ULTRASOUND NOZZLE
    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.

  • LAYER-FORMING NOZZLE EXIT FOR FUSED FILAMENT FABRICATION PROCESS
    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.

  • JOULE HEATING FOR IMPROVED INTERLAYER BONDING IN FUSED FILAMENT FABRICATION OF METALLIC OBJECTS
    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.

  • ADDITIVE MANUFACTURING WITH TEMPORAL AND SPATIAL TRACKING OF THERMAL INFORMATION
    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.

  • FUSED FILAMENT FABRICATION NOZZLE WITH CONTROLLABLE EXIT SHAPE
    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.

  • REMOVABLE SUPPORT STRUCTURE WITH AN INTERFACE FORMED BETWEEN THERMALLY MISMATCHED BULK METALLIC GLASSES
    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.

  • BULK METALLIC GLASS PRINTER WITH SHEARING ENGINE IN FEED PATH
    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.

  • Ceramic structures for enhanced shape memory and pseudoelastic effects
    Patent number: 9018117
    Abstract: Shape memory and pseudoelastic martensitic behavior is enabled by a structure in which there is provided a crystalline ceramic material that is capable of undergoing a reversible martensitic transformation and forming martensitic domains, during such martensitic transformation, that have an elongated domain length. The ceramic material is configured as a ceramic material structure including a structural feature that is smaller than the elongated domain length of the ceramic material.
