An extrusion apparatus for producing thee-dimensional objects comprises at least one die, an extruder, and a rotatable cutter plate. The die is disposed adjacent to an outlet end of the extruder. The die forms an opening defining a two-dimensional shape, and the extruder forces an extrudable material through the opening in the die. The rotatable cutter plate is disposed adjacent to the die. The cutter plate is configured to obstruct different portions of the die opening at different times as the cutter plate rotates so as to vary the shape of the extrudable material forced through the opening in the die and thereby create a three-dimensional shape. The cutter plate is configured to fully obstruct the opening in the die during each revolution of the cutter plate so as to separate the extrudable material forced through the opening in the die into individual objects.
An extrusion apparatus for producing a three-dimensionally shaped product, comprising:
A rotatable cutter plate assembly for use in producing a three-dimensional shape, the plate assembly can be disposed adjacent to at least one die having an opening defining a two-dimensional shape, said die typically disposed adjacent to an extruder forcing an extrudable material through the opening in the die, the plate assembly comprising:
A method for producing a three-dimensionally shaped product, said method comprising:
