  • Publication number: 20110232855
    Abstract: A digital manufacturing system comprises a build chamber, a build platform disposed within the build chamber, at least one extrusion line configured to heat a metal-based alloy up to a temperature between solidus and liquidus temperatures of the metal-based alloy, a deposition head disposed within the build chamber and configured to deposit the heated metal-based alloy onto the build platform in a predetermined pattern, an umbilical having a first end located outside of the build chamber and a second end connected to the deposition head, and at least one gantry assembly configured to cause relative motion between the build platform and the deposition head within the build chamber, where the at least one gantry assembly comprises a motor disposed outside of the build chamber.

  • Patent number: 8014889
    Abstract: The present invention is a method (10) for manufacturing a three-dimensional object. The method (10) includes receiving (14) digital information of the three-dimensional object over a communication line and building (30) the three-dimensional object based at least in part on the received digital information, where at least part of the three-dimensional object is built by rapid manufacturing, and where the three-dimensional object comprises an exterior surface. The method also includes vapor smoothing (32) at least a portion of the exterior surface of the three-dimensional object.

  • Publication number: 20110074065
    Abstract: A ribbon liquefier comprising an outer liquefier portion configured to receive thermal energy from a heat transfer component, and a channel at least partially defined by the outer liquefier portion, where the channel has dimensions that are configured to receive the ribbon filament, and where the ribbon liquefier is configured to melt the ribbon filament received in the channel to at least an extrudable state with the received thermal energy to provide a melt flow. The dimensions of the channel are further configured to conform the melt flow from an axially-asymmetric flow to a substantially axially-symmetric flow in an extrusion tip connected to the ribbon liquefier.

  • Publication number: 20110076496
    Abstract: A consumable material for use in an extrusion-based digital manufacturing system, the consumable material comprising a length and a cross-sectional profile of at least a portion of the length that is axially asymmetric. The cross-sectional profile is configured to provide a response time with a non-cylindrical liquefier of the extrusion-based digital manufacturing system that is faster than a response time achievable with a cylindrical filament in a cylindrical liquefier for a same thermally limited, maximum volumetric flow rate.

  • Patent number: 5503785
    Abstract: Processes and apparatus are disclosed for producing three-dimensional objects having overhanging portions freely suspended in space without any material of the object in direct, supporting engagement therewith in the final geometry of the object. A support structure is formed by depositing material which will be under the ultimately suspended portions of the object to be formed, during a process in which material is built up in layers to form the object as well as the underlying support structure. A readily removable support structure is formed along an interface with the underside of the suspended portion of the object structure. A weak, removable or breakable joint is formed along that interface by the use of an interface material which forms a weak or dissolvable bond with the material of the object. The release material may be deposited as a separation layer, or as a thin coating.

  • Patent number: 5340433
    Abstract: Apparatus incorporating a movable dispensing head provided with a supply of material which solidifies at a predetermined temperature, and a base member, which are moved relative to each other along multiple axes in a predetermined pattern to create three-dimensional objects by building up material discharged from the dispensing head onto the base member at a controlled rate. The apparatus is preferably computer driven in a process utilizing computer aided design (CAD) and computer-aided (CAM) software to generate drive signals for controlled movement of the dispensing head and base member as material is being dispensed.Three-dimensional objects may be produced by depositing repeated layers of solidifying material until the shape is formed. Any material, such as self-hardening waxes, thermoplastic resins, molten metals, two-part epoxies, foaming plastics, and glass, which adheres to the previous layer with an adequate bond upon solidification, may be utilized.
