Pellet 3D printing

As a raw material format, pellets are most commonly associated with forming processes like injection molding. However, some 3D printers are fitted with pellet hoppers and extruders instead of filament extruders.

There are several benefits to pellet extrusion, including low material cost compared to filament, the ability to use recycled materials, and the ability to print very large parts (thanks to wider nozzles and faster material flow).

Pellet-extruding 3D printers are often built for construction or other large-format printing projects.
