Filaflex

Filaflex: The Ultimate Flexible Filament

Revolutionize your 3D printing with elasticity, adhesion and durability

Discover the most renowned flexible filament on the market, developed by Recreus. Filaflex transforms any 3D printer into a tool for creating flexible, elastic and highly durable parts.

What is Filaflex?

Filaflex is a highly elastic and resistant TPU (thermoplastic polyurethane) filament designed to print flexible objects on any FDM printer. Unlike conventional rigid filaments, Filaflex bends, stretches and adapts, opening new possibilities in prototyping, footwear, fashion, medicine and beyond.

Thanks to its exclusive formula developed by Recreus, Filaflex does not require a heated bed, adheres perfectly to the print surface and avoids warping.

When and Why Was Filaflex Born?

Filaflex was created in 2013 in Elda, a town in the province of Alicante, Spain. It was born from the need to develop a truly elastic and innovative material—something that was missing from the 3D printing market at the time.

Unlike rigid filaments available back then, Filaflex aimed to expand the possibilities of additive manufacturing by introducing flexibility and softness to 3D printed parts.

Key Features

  • High elasticity: stretch up to 950% in its most flexible version (Filaflex 60A).
  • No warping and no heated bed required: prints directly on glass, without BuildTak or blue tape.
  • Excellent interlayer adhesion: more resistant and uniform parts.
  • Material Safety: Non-toxic and skin-safe formulation.
  • Wide range of hardnesses: 60A (ultra-flexible), 70A, 82A (standard), and 95A (semi-rigid).

Discover the Advantages of Filaflex

Elasticity that Adapts

Prints with true elasticity: returns to shape after deformation without losing structure. Ideal for wearables, grippers, and flexible mechanisms.

Outstanding Bed Adhesion

Print directly onto glass or common surfaces: no heated bed, tape or sprays required. Zero warping, maximum reliability.

Durability & Chemical Resistance

Built to last. Withstands solvents and impact. Perfect for demanding environments and functional 3D parts.

Skin Contact Safety

Safe for skin contact, odorless and FDA/EU compliant. Trusted by professionals for medical, fashion and industrial applications.

Recommended Applications

  • Custom footwear and orthopedic insoles.
  • Wearables and medical devices.
  • Gaskets, seals and flexible components.
  • Prosthetics, grippers and soft robotics.
  • Fashion accessories and textile elements.

Filaflex Range by Hardness

Filaflex 60A

The most elastic of all. Perfect for parts that require extreme deformation and recovery.

Filaflex 70A

Great balance between flexibility and ease of printing. High interlayer bonding strength.

Filaflex 82A

The most versatile and widely used formulation worldwide. Compatible with most extruders.
