    Abstract: Printing devices and methods are provided that utilize high throughput extrusion to generate a printer material, such as a three-dimensional object. High-throughput extrusion systems as provided volumetrically pre-heat an extruded filament to a desired pre-heat temperature, and then either maintain or heat the extruded filament to a desired melt temperature prior to having the filament extruded out of the system and onto a surface, such as a build platform. By pre-heating the filament prior to heating it to the temperature at which it is excluded, it helps increase the throughput of the system. Likewise, by doing the heating volumetrically, it further helps increase the throughput of the system. Various embodiments of devices and methods typically used for printing in conjunction with the disclosed high throughput systems are also provided.

    Abstract: Fused deposition model printer system. The system prints cold slurry substances and includes a source of a cold slurry substance with a print platform supported for at least three axes of motion under computer control. An extruder head system including a nozzle extrudes a stream of the cold slurry substance from the source onto the print platform, the extruder head including a heater. A cryogen line is provided having a perforated section for surrounding the continuous stream of the cold slurry substance to spray a cryogen onto the cold slurry substance to cool it upon extrusion. A chilled compartment or freezer is provided in which the print platform, extruder head system, and cryogen line are contained to maintain those components at a selected temperature whereby the cold slurry substance is printed to form a desired three dimensional shape.

    Abstract: Printing devices and methods are provided that utilize high throughput extrusion to generate a printer material, such as a three-dimensional object. High-throughput extrusion systems in accordance with the present disclosure volumetrically pre-heat an extruded filament to a desired pre-heat temperature, and then either maintain or heat the extruded filament to a desired melt temperature prior to having the filament extruded out of the system and onto a surface, such as a build platform. By pre-heating the filament prior to heating it to the temperature at which it is excluded, it helps increase the throughput of the system. Likewise, by doing the heating volumetrically, it further helps increase the throughput of the system. Various embodiments of devices and methods typically used for printing in conjunction with the disclosed high throughput systems are also provided for in the present disclosure.
