Our aim is to create the knowledge hub for 3D Printing covering all minor and major topics. Providing one source of reliable Information for everybody regardless of Beginner or Expert.

Introduction to Fused Granulate Fabrication (FGF)

Fused Granulate Fabrication (FGF) is a groundbreaking technology in the realm of 3D printing, also known as additive manufacturing. This blog post delves into FGF, providing a comprehensive overview of its workings, benefits, drawbacks, and comparisons with other technologies like FFF (Fused Filament Fabrication) and FDM (Fused Deposition Modeling), all under the umbrella of Material Extrusion (MEX).

Understanding Material Extrusion (MEX)

The Basics of MEX

Material Extrusion is a parent technology in 3D printing where material is dispensed through a nozzle or orifice. It’s a popular choice due to its simplicity and effectiveness.

FGF vs. Other MEX Technologies

FGF stands out within the MEX category for its unique approach to material handling and deposition. Unlike FFF and FDM, which use filament, FGF utilizes granulated material, offering distinct advantages.

How FGF Works

FGF works by extruding heated, granulated plastic through a nozzle, layer by layer, to create a 3D object. This process allows for greater material flexibility and efficient use.

Advantages of FGF

  • Material Efficiency: FGF’s use of granulated plastic reduces waste and can be more cost-effective.
  • Scalability: Larger nozzle sizes allow for faster printing of larger objects.
  • Material Variety: FGF can work with a wider range of materials, including recycled plastics.

Disadvantages of FGF

  • Surface Finish: The larger granules can result in a rougher surface finish compared to FFF or FDM.
  • Precision: FGF may struggle with the intricate details that smaller filament printers can achieve.

Comparing FGF with FFF and FDM

Similarities and Differences

While FGF, FFF, and FDM all fall under MEX, they differ in their material handling. FFF and FDM use filaments, providing finer resolution but at the cost of material versatility and printing speed.

Pros and Cons Analysis

  • FGF: Best for large, fast prints and material efficiency, but not ideal for detailed work.
  • FFF/FDM: Suitable for detailed and smooth prints, but less efficient for large-scale manufacturing.

Future of FGF in Additive Manufacturing

FGF’s potential in sustainability, especially with recycled materials, positions it as a key player in the future of 3D printing. Its scalability makes it ideal for industrial applications.


Fused Granulate Fabrication stands as a powerful technology in the 3D printing landscape. Its unique approach to material extrusion offers both opportunities and challenges, making it a compelling choice for specific applications in additive manufacturing.


What sets FGF apart from FFF and FDM in 3D printing? FGF uses granulated material, enabling larger scale prints and material diversity.

Is FGF more cost-effective than other MEX technologies? Yes, due to its efficient use of granulated material and potential for using recycled plastics.

Can FGF achieve the same level of detail as FFF or FDM? No, FGF typically has a rougher finish and is less suited for intricate details compared to FFF/FDM.

What are the main advantages of FGF? Material efficiency, scalability, and a broader range of usable materials.

Is FGF suitable for industrial applications? Yes, its scalability and material efficiency make it well-suited for industrial uses.
