FLEX filament is a special type of flexible material designed for 3D printing that combines the elasticity of rubber with the strength of plastic. This type of filament is made from thermoplastic elastomers (TPE, TPU, or TPC), which enable the printing of flexible, stretchable, and impact-resistant parts.
FLEX filament is ideal for the production of seals, protective covers, bumpers, handles, damping elements, or ergonomic components, where flexibility, durability, and shape recovery are needed.


Unlike classic rigid filaments, FLEX makes it possible to create prints that deform under pressure but always return to their original shape.
This makes it popular both in technical applications and in the creation of functional prototypes and design elements. With the printer properly configured, it is possible to achieve uniform printing without gaps or deformations, while the resulting parts have a smooth and flexible surface.Main advantages of FLEX filaments:
High elasticity and tear resistance
Impact resistance and ability to absorb vibrations
Good layer adhesion and dimensional stability
Can be bent, stretched, and compressed without damage
Resistance to chemicals, grease, and wear
Suitable for mechanically stressed and damping components
Printing with flexible filaments requires a slightly different approach than with classic materials such as PLA filament or ABS filament. A direct drive extruder (Direct Drive) is recommended, as it provides better control over the feeding of flexible filament. The nozzle temperature usually ranges between 210–240 °C, and the print bed can be heated to 50–60 °C.
For best results, a lower print speed (20–40 mm/s) is recommended so that the filament has time to be deposited properly. After printing, the parts can be further processed – for example, trimmed or thermally shaped without losing their flexibility.
FLEX filaments are used wherever a combination of flexibility, durability, and reliability is needed.
Typical applications include:Seals, protective covers and sleeves
Shock and vibration dampers
Bumpers, pads, tapes, hoses, and sealing rings
Handles, anti-slip parts, or sports equipment
Decorative and functional design components
In our offer you will find FLEX filaments with different hardness levels (usually обозначенные in Shore units – e.g. Shore 85A to 98A). Softer types are very flexible, while harder ones provide greater stability and strength. FLEX is available in various colors, from classic black and white to transparent and bold shades, allowing you to tailor the appearance of prints as needed.
Thanks to its properties, FLEX filament is an ideal solution for applications where elasticity, impact resistance, and shape memory are important.
Prints made from this material retain their properties over the long term, even under repeated stress.The FLEX Filament Category offers a wide selection of flexible and durable filaments for professional and home 3D printing. A perfect choice for anyone who wants to experiment with functional materials, print flexible components, and harness the full potential of 3D printing in practice.
