Prototyping to series production

Comparison of methods

In the field of material extrusion, two promising methods have emerged that we use today for the production of end products, tool manufacture and also the prototyping of end products.

Fused Filament Fabrication

In fused filament fabrication, a relatively expensive filament (plastic wire) made of thermoplastic material is heated by a liquefier (extruder) and applied layer by layer to form a component. The size of the nozzles can be customized and changed for each part.

Fused Granulate Fabrication

Fused Granulate Fabrication (FGF or Pellet Printing) is a similar process to FFF, but instead of an expensive filament, a cheaper granulate (pellet) of the material is used. The mechanics are similar to the FFF machine, but with a screw extrusion system similar to traditional plastic extrusion. A servo motor drives the screw, which feeds the pellets through a heated barrel so that the material gradually heats up and melts. Similar to FFF, the material is then pressed through a nozzle. The nozzles can also be adapted to the respective part and application.

Technical possibilities

  • Size: up to 600x600x600
  • Z-resolution: 0.1 to approx. 1 mm
  • Nozzle size: from 0.2 to 3 mm
  • Material PLA, ASA, ABS, PET, PP-CF, PP-GF, BDP (Green-TEC), PLA-ESD

Main parameters

The manufacturing costs are primarily influenced by the following properties:

  • Layer height
  • Nozzle size
  • Material

Conclusion from the comparison

Due to the rather expensive material costs, FFF is suitable for small, delicate parts where the material is not such a major cost factor.

Due to the lower material costs, FGF is more suitable for larger and coarser parts where the material costs are a relevant cost factor.
