1. A die plate changing system configured to hold first and second die plates and selectively transition the first and second die plates into and out of communication with a material source, the die plate changing system comprising:
a frame having a body defining a first recess configured to receive the first die plate and a second recess configured to receive the second die plate, wherein the first and second die plates are disposed in the first and second recesses, respectively, and are heated; and
a movement assembly operably coupled to the frame and configured to selectively move the frame linearly along a direction between a first position, where the first die plate is configured to receive material from the material source, and a second position, where the second die plate is configured to receive the material from the material source, whereby the first position of the frame and the second position of the frame are offset from one another along the direction.
