Product description

LAST UNITS! Filament wound on an old-type spool. Spool dimensions: 200 mm x 84 mm. The spool is not compatible with BambuLab AMS. It can be used with BambuLab AMS Lite.

FiberFlex 40D is a flexible TPU filament with a Shore hardness of 40D that allows for fast and precise 3D printing at speeds of up to 45 mm/s without compromising print quality. This material is designed to make printing flexible models simple and convenient – the filament feeds easily and layers bond perfectly, ensuring strong and aesthetically pleasing prints.

FiberFlex 40D stands out for its high resistance to impact, abrasion, low temperatures, and chemicals, making it suitable for a wide range of applications – from hobby projects to professional models requiring flexibility and durability.

The filament is available in a wide range of colors, allowing you to match the material to any project.

RAL/Pantone

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.
