Fused granulate fabrication (FGF) is an Screw extrusion-based 3D printing technique where plastic pellets are fed and extruded through a nozzle. FGF may be referred to as Fused Granulate Fabrication, Fused Particle Fabrication, or Pellet 3D Printing.
FGF and FFF 3D printing differ primarily in material use. FGF uses melted plastic pellets, offering stronger extrusion and suitability for large industrial parts, lower costs, and environmentally friendly production. FFF uses plastic filaments, which can suffer material performance loss and filament breakage.
Pellet 3D printers offer outstanding material adaptability, supporting both traditional commercial thermoplastics and recycled materials like PLA, ABS, PETG, and TPU. Additionally, they are compatible with popular carbon fiber-reinforced materials for FGF printing, including PC-CF, PA-CF, PLA-CF, and ABS-CF.
