Fiberlogy Flexible Filaments are advanced TPU (thermoplastic polyurethane) and TPE (thermoplastic elastomer) 3D printing materials designed for projects requiring flexibility, durability, and resilience. This product category includes a variety of flexible filament types - from the ultra-soft FiberFlex 30D, through the versatile FiberFlex 40D and matte MattFlex 40D, to the carbon fiber-reinforced FiberFlex CF. Such a wide range allows you to match the perfect material to your project and printing experience level.

FiberFlex 30D is a very soft filament (30D Shore hardness) with rubber-like properties. It’s ideal for parts that need to withstand bending, squeezing, or stretching, such as gaskets, seals, and shock absorbers. Like classic TPU/TPE filaments, it works best with a direct drive extruder and lower printing speeds.

FiberFlex 40D offers greater hardness and more versatility. It enables fast and stable 3D printing (up to 45 mm/s) while maintaining high impact resistance, abrasion resistance, chemical resistance, and low-temperature tolerance. It’s suitable for both hobby and professional applications.

MattFlex 40D stands out with its matte, non-gloss finish, which delivers clean, aesthetic prints without the need for post-processing. This flexible filament combines excellent printability with an attractive look. It can also be printed at speeds of up to 60 mm/s without sacrificing quality.

FiberFlex CF is an innovative TPU filament reinforced with 20% carbon fiber. It features increased stiffness (60D Shore hardness), temperature resistance up to 90 °C, and antistatic as well as electroconductive properties. It’s perfect for technical and industrial applications where flexibility must be combined with dimensional stability and durability.

Fiberlogy flexible filaments are ideal for functional projects where performance matters. They’re great for hobbyists and professionals alike - perfect for protective parts, phone cases, mounts, and technical components exposed to stress and strain. Whether you need a soft, rubber-like filament or a more rigid TPU, you’ll find the perfect match for your 3D printing needs.
