Development of a new technology which enables to reinforce parts with continuous fibres, multiplying in this way the mechanical properties while reducing the weight.

The CFIP (Continuous Fiber Injection Process) technology is a new post-processing, developed and patented by Eurecat, based on injecting the continuous fibers simultaneously with liquid resin inside tubular cavities in the part. Once cured the part, the solidified resin works as a mechanical interface between the fibers and the rest of the part.

CFIP technology aims to enable the use of 3D printing in new applications where high mechanical and lightweghting performance is required. The good results achieved demonstrate the added value that this technology brings in different sectors such as aerospace, automotive, sporting goods or health.

This innovative technology, which has counted with the participation of the Product Development Unit and the New Manufacturing Processes Unit, allows to reinforce parts made with any type of material, including plastics (rigid or flexile), metals or ceramics.

In addition, it also enables to integrally join different parts by providing fiber continuity between them, achieving in this way ultra-high joining performance. This allows the manufacturing of multi-material and multi-process structures, selecting the most efficient material and process according to the requirements in each zone of the structure.

Advantages of carbon fiber for 3D printing:

  • Reinforcing fibers in all directions and following complex trajectories
  • Stronger and lighter parts
  • Reinforcement of a wide variety of materials (plastic, metals, ceramics)
  • Integral joining of different parts (multi-material and multi-process structures)

Last May, the CFIP technology was awarded by the JEC World Innovation Award in the additive manufacturing category, in recognition of the innovation it brings to the industry.
