Product description

Fiberlogy MattFlex 40D is a modern, flexible 3D printing filament featuring a matte finish and rubber-like properties. It is an excellent alternative to traditional TPU filaments, offering not only ease of printing but also an attractive appearance. The matte surface effectively hides layer lines, giving models a clean, aesthetic look without the need for post-processing.

Unlike many flexible filaments, MattFlex 40D allows high printing speeds – up to 60 mm/s – without compromising quality. This makes it user-friendly and suitable for both hobbyists and professional FDM users.

The filament offers impressive durability: it can stretch up to 6 times its length, withstand compression up to 50%, and has high impact resistance and elasticity. Additionally, MattFlex 40D is resistant to chemicals and low temperatures, making it suitable for demanding technical and industrial applications.

Thanks to its unique combination of flexibility and matte appearance, Fiberlogy MattFlex 40D is ideal for producing functional seals, shock absorbers, flexible hinges, guards, and load-bearing parts. At the same time, it is perfect for projects where durability is required alongside an elegant 3D printed finish.

Fiberlogy MattFlex 40D is a filament for users who want to combine the advantages of flexible materials with an attractive matte finish – a perfect choice for both home and professional applications.

To make it easier to choose the right color variant, we provide RAL and Pantone equivalents for filaments wherever possible. The given values are approximate and are intended to reflect the actual filament shade as closely as possible.

Why not HEX?

Providing the color of 3D printing filament in HEX format does not make sense because this notation was created to describe colors displayed on screens (RGB – monitors, TVs, mobile devices). HEX defines a mix of red, green and blue light, meaning a digital color. With filaments, however, we deal with a physical material. The same filament may look different in various photos and HEX cannot accurately represent the actual appearance of the material.

Much better references are color systems used in printing and industry, such as RAL or Pantone, which are based on real samples and allow for comparison of colors in physical reality.
