FiberFlex+CF Filament - S2

Description

Fiberlogy FiberFlex CF is an advanced 3D printing filament that combines the flexibility of thermoplastic polyurethane (TPU) with the exceptional strength of carbon fiber. The material offers excellent shock-absorbing properties, elasticity, and high mechanical strength, making it an ideal choice for projects requiring flexible and durable prints.

FiberFlex CF contains 20% carbon fiber, which increases the material’s stiffness to 60D on the Shore scale, allowing for the creation of precise and durable parts. The increased stiffness makes the filament easier to print than other flexible TPU materials. Additionally, it has antistatic and electrically conductive properties, and its temperature resistance up to 90°C allows it to be used in harsh mechanical and environmental conditions.

FiberFlex CF is ideal for applications requiring a combination of flexibility and strength—such as shock absorbers, gaskets, protective components, industrial structures, or mechanical parts exposed to heavy loads and harsh conditions. The filament is resistant to deformation and maintains high dimensional accuracy, making it an excellent solution for professionals and hobbyists alike.

The FiberFlex CF production process is closely monitored, ensuring consistent filament properties, print repeatability, and reliability even in demanding projects.

Fiberlogy FiberFlex CF is a filament for users seeking a material that combines the flexibility of TPU with the strength of carbon fiber, offering precision, mechanical resistance, and the ability to perform in harsh conditions —ideal for technical projects and functional components.
