Economical large-format 3D printing with Q.BIG 3D’s VFGF process

Large-volume 3D printing of components is becoming increasingly economically feasible thanks to the VFGF (Variable Fused Granulate Fabrication) process from Q.BIG 3D. This process offers an efficient solution for the production of large components by combining the advantages of additive manufacturing with cost-efficient materials.

The VFGF process is characterized by the use of a variable nozzle that can switch between turbo and detail mode. In turbo mode, the nozzle enables a high material throughput, ideal for the rapid creation of in-fill areas within a geometry. In detail mode, on the other hand, the nozzle ensures precise and high-quality surfaces, which is particularly advantageous for complex structures such as fastening elements or thin-walled areas. This flexibility makes it possible to produce large components with high resolution and short production times at the same time.

A key advantage of the VFGF process is the use of commercially available plastic granules instead of expensive filaments. This significantly reduces material costs and makes large-format 3D printing economically competitive with traditional, tool-based processes such as injection molding. It also eliminates the high tooling costs and long lead times that characterize conventional methods.

Practical examples show the versatility of the VFGF process. In caravan construction, thin-walled functional samples were manufactured quickly and precisely, while in the automotive sector, precise measuring devices could be produced in a short time. Another example is a pipe elbow for a hydroelectric power plant, which was realized within four weeks thanks to the VFGF process, achieving a cost saving of 50 percent compared to conventional methods.

The VFGF process from Q.BIG 3D opens up new possibilities in large-format 3D printing by combining economical production, high precision and flexible application. This innovation makes a significant contribution to further advancing additive manufacturing and opening up new market potential.
