This printer has an industrial build envelope of 4’x4’x4’ (1220mm x 1220mm x 1220mm). A typical filament extruder is not capable of pumping enough plastic to cover this massive build volume. Therefore, Massive Dimension’s MDPH2 pellet extruder, which is capable of depositing 1 kg of molten plastic an hour, will be used to generate the layers for some massive objects. However, the MDPH2 weighs nearly 18lbs (~), which re
