摘要：
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.
