20120068378 | METHOD FOR BUILDING THREE-DIMENSIONAL MODELS WITH EXTRUSION-BASED ADDITIVE MANUFACTURING SYSTEMS - A method for building a three-dimensional model with an extrusion-based additive manufacturing system having an extrusion head, the method comprising depositing a consumable material from a liquefier assembly at an extrusion rate to substantially normalize a meniscus height within the liquefier assembly. | 03-22-2012 |
20120070523 | LIQUEFIER ASSEMBLY FOR USE IN EXTRUSION-BASED ADDITIVE MANUFACTURING SYSTEMS - A liquefier assembly for use in an extrusion-based additive manufacturing system, the liquefier assembly comprising a downstream portion having a first average inner cross-sectional area, and an upstream having a second average inner cross-sectional area that is less than the first inner cross-sectional area, the upstream portion defining a shoulder configured to restrict movement of a melt meniscus of a consumable material. | 03-22-2012 |
20120162305 | PRINT HEAD FOR USE IN FUSED DEPOSITION MODELING SYSTEM - A print head for use in a fused deposition modeling system, the print head includes a cartridge assembly and a liquefier pump assembly retained by the cartridge assembly. | 06-28-2012 |
20120164256 | PRINT HEAD ASSEMBLY AND PRINT HEAD FOR USE IN FUSED DEPOSITION MODELING SYSTEM - A print head assembly that includes a print head carriage and multiple, replaceable print heads that are configured to be removably retained in receptacles of the print head carriage. The print heads each include a cartridge assembly and a liquefier pump assembly retained by the cartridge assembly. | 06-28-2012 |
20130161439 | SPOOL ASSEMBLY WITH LOCKING MECHANISM FOR ADDITIVE MANUFACTURING SYSTEM, AND METHODS OF USE THEREOF - A spool assembly comprising a housing structure, a spool rotatably retained in an interior region of the housing structure, and a sealed sheath encasing the housing structure to define a barrier for the encased housing structure and the rotatably retained spool. The spool assembly further comprises a locking arm disposed outside of the sealed sheath and configured to operably engage the spool through the sealed sheath and through the housing structure in a manner that does not penetrate the sealed sheath, where the locking arm prevents the spool from rotating relative to the housing mechanism when operably engaged with the spool. The locking arm may disengage from the spool in a hands-free manner when the spool assembly is loaded into a bay of an additive manufacturing system. | 06-27-2013 |
20130161442 | SPOOL ASSEMBLY FOR ADDITIVE MANUFACTURING SYSTEM, AND METHODS OF MANUFACTURE AND USE THEREOF - A spool assembly for use in an additive manufacturing system, comprising a spool rotatably retained in a sealed sheath in a hub-less manner, and a locking mechanism configured to operably engage with the spool to prevent the spool from rotating. | 06-27-2013 |
20140120194 | PRINT HEAD ASSEMBLY AND PRINT HEAD FOR USE IN FUSED DEPOSITION MODELING SYSTEM - A print head assembly that includes a print head carriage and multiple, replaceable print heads that are configured to be removably retained in receptacles of the print head carriage. The print heads each include a cartridge assembly and a liquefier pump assembly retained by the cartridge assembly. | 05-01-2014 |
20140120197 | LIQUEFIER ASSEMBLY FOR USE IN EXTRUSION-BASED ADDITIVE MANUFACTURING SYSTEMS - A liquefier assembly for use in an extrusion-based additive manufacturing system, the liquefier assembly comprising a downstream portion having a first average inner cross-sectional area, and an upstream having a second average inner cross-sectional area that is less than the first inner cross-sectional area, the upstream portion defining a shoulder configured to restrict movement of a melt meniscus of a consumable material. | 05-01-2014 |
