CFIP, a Revolutionary Post-Processing Technique That Reinforces 3D Printed Parts With Continuous Fibers

In additive manufacturing, there are four fundamental stages: design, lamination, printing and post-processing. This last step is especially important, regardless of the manufacturing technology used, as it gives the parts an optimal surface finish. In addition, many post-processing techniques are used to reinforce the physical and mechanical properties of the parts. Take for example a new post-processing system that is expected to set a milestone in the additive manufacturing industry. The so-called “Delta” is a machine developed by the startup Reinforce3D using their patented CFIP (Continuous Fibre Injection Process) technology. This solution makes it possible to reinforce 3D printed parts by injecting continuous fibers making them lighter while allowing for a higher mechanical performance.

Reinforce3D was born as a project within the Eurecat technology center, located in Catalonia, Spain. But since 2022, an investment fund decided to invest and launch the startup we know today. Specifically, it was founded by BeAble Innvierte Kets Fund (BIKF), Eurecat and Marc Crescenti with the aim of developing a new post-processing solution for the 3D printing industry. Led by its CEO, Blanca Garro, the company has been growing while maturing its technology in a short period of time. Thus, its Delta industrial solution, which uses the CFIP process, will be presented during Formnext 2023, in Frankfurt, and aims to change the paradigm of post-treatment that we knew until now. To understand a little more about what this new system consists of, as well as the applications Delta and the performance of CFIP technology and industries it is aimed at, we tell you below all its properties and characteristics.

A Closer Look at Reinforce3D’s Delta and the CFIP Technology

The process of reinforcing 3D printed parts using CFIP represents a significant innovation in the additive manufacturing industry. What was once only a developing technology is now a reality with the advent of Delta. Instead of strengthening parts during the manufacturing process, as is common in conventional 3D printing, the CFIP system focuses on improving part properties in a subsequent step. Specifically, this method involves injecting continuous fibers into the parts to drastically improve their strength and performance. Instead of using short fibers, continuous fibers (such as carbon fibers) are injected into pre-designed tubular cavities in the part. These fibers are carried by a resin that cures, strengthening the structure of the part.
