20150314531 | METHODS FOR COMPOSITE FILAMENT THREADING IN THREE DIMENSIONAL PRINTING - Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to applying the filament from the conduit nozzle. | 11-05-2015 |
20150290875 | THREE DIMENSIONAL PRINTING OF COMPOSITE REINFORCED STRUCTURES - Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle. | 10-15-2015 |
20150266243 | THREE DIMENSIONAL PRINTER FOR FIBER REINFORCED COMPOSITE FILAMENT FABRICATION - Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to applying the filament from the conduit nozzle. | 09-24-2015 |
20150210007 | 3D PRINTING WITH KINEMATIC COUPLING - A three dimensional printer incorporates a kinematic coupling between the build platform and movable stage which holds the build platform, of three curved protrusions attached to one of the build platform or the movable stage and six locating features formed in receivers of the other. At least two flexures differentially change a Z position of each of two of the curved protrusions. 3D printing is paused at a preset level of completion, and the build platform may be removed for external operations. A print resume circuit resumes printing of additional printed layers at the previous position in response to a return detection circuit that responds to an input (e.g., a touch screen confirmation). | 07-30-2015 |
20150108677 | THREE DIMENSIONAL PRINTER WITH COMPOSITE FILAMENT FABRICATION - Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle. | 04-23-2015 |
