20090314391 | SYSTEM AND METHOD FOR BUILDING THREE-DIMENSIONAL OBJECTS WITH METAL-BASED ALLOYS - 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. | 12-24-2009 |
20090321972 | Vapor smoothing surface finishing system - A system and method is provided for vapor smoothing a rapid manufactured three-dimensional object. A cabinet housing has a sealable interior. A heated vapor chamber in the interior of the cabinet housing contains solvent that is vaporizable to fill the vapor chamber with vapor for smoothing the object when the object is placed in the vapor chamber. A drying chamber is also provided in the interior of the cabinet housing that is separate from the vapor chamber for drying the object when the object is moved from the vapor chamber to the drying chamber. | 12-31-2009 |
20100327479 | CONSUMABLE MATERIALS HAVING CUSTOMIZED CHARACTERISTICS - A compounding system for forming a customized consumable material, comprising a plurality of drive mechanisms configured to feed stock materials at independent rates, and an extrusion component configured to receive the fed stock materials, and further configured to at least partially melt and blend the received stock materials to provide the consumable material in an extrudable state. Upon solidifying, the consumable material comprises customized characteristics based on characteristics of the stock materials. | 12-30-2010 |
20110232855 | SYSTEM AND METHOD FOR BUILDING THREE-DIMENSIONAL OBJECTS WITH METAL-BASED ALLOYS - 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. | 09-29-2011 |
20120018926 | Three-Dimensional Parts Having Porous Protective Structures - Three-dimensional parts having porous protective structures built with powder-based additive manufacturing systems, the porous protective structures being configured to protect the three-dimensional parts from damage during de-powdering processes. | 01-26-2012 |
20120231225 | CORE-SHELL CONSUMABLE MATERIALS FOR USE IN EXTRUSION-BASED ADDITIVE MANUFACTURING SYSTEMS - A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a first thermoplastic material, and a shell portion of a second thermoplastic material that is compositionally different from the first thermoplastic material, where the consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional object, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament. | 09-13-2012 |
20130224423 | ADDITIVE MANUFACTURING METHOD FOR BUILDING THREE-DIMENSIONAL OBJECTS WITH CORE-SHELL ARRANGEMENTS, AND THREE-DIMENSIONAL OBJECTS THEREOF - A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a first thermoplastic material, and a shell portion of a second thermoplastic material that is compositionally different from the first thermoplastic material, where the consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional object, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament. | 08-29-2013 |
