Extrusion-based 3D printing is one of the most common additive manufacturing methods, but the technology often requires materials to be fabricated to filaments, which limits the applicability. In addition, filament-based printing poses challenges such as back-pressure buildup or rough surface formation caused by flow instability. Pellet extrusion 3D printing is a versatile, filament-free capability that enables additive manufacturing of a variety of polymeric materials that are difficult to form filaments. This capability also enables prototype printing using new polymers or nanocomposites to assess their printability.
