What is the minimum pellet volume required for the EX2?

Since polymers and additives vary widely, determining exact minimum amounts can be challenging. As a general rule when operating the extruders, ensure the barrel remains full.

The EX2 screw void is 1.75 cubic in, however, in order to push that material out of the barrel, you will need at least that same amount in the hopper to push the material through effectively.
