A type of material extrusion additive manufacturing where polymer pellets, the same raw material used in injection molding, are melted, then fed into a heated extruder and deposited on the current build layer. It varies from FDM/FFF in size of the build volume, the diameter of the nozzle, and use of pellet material instead of filament. These systems utilize large industrial gantries and material handling equipment from injection molding to position and feed material to the extruder. The build volume size is only limited by the size of the gantry used. It is often utilized to create large tools and molds or large structures.
Abbreviated as BAAM.
