Flexibility of the new generation

Spectrum PEBA is based on a polyether-Block-amide (PEBA) copolymer and represents a new generation of flexible 3D printing materials – lighter, more dynamic and more durable than TPU.
Thanks to its unique molecular structure, Spectrum PEBA does not dampen energy like conventional TPU, but saves and releases it again. This ensures an exceptionally quick return to the original shape and high reaction capability of the material.

Dynamic feedback – high rebound effect
The high-rebound effect means that parts printed with Spectrum PEBA react dynamically and flexibly – instead of absorbing energy, they release them in the form of a rebound. In practice, this means, for example, a PEBA ball bounces off the ground, while shock-absorbing or sporting components retain their lightness and reactivity.

Designed for maximum performance in all conditions
The filament has a shore hardness of 92A and a breaking elongation of over 500%. It retains its mechanical and elastic properties in a wide temperature range from -40°C to +80°C. Spectrum PEBA remains flexible and dimensionally stable, where other elastomers lose their properties. The low density of 1.02 g/cm³ makes it possible to produce lightweight, flexible and robust functional components.

Stable printing process and excellent layer adhesion
Spectrum PEBA ensures excellent coating adhesion and a stable printing process. Thanks to its high elasticity, shock-absorbing components, flexible hinges, sport and protective components can be produced with a long life. Easy to process filament on direct-drive printers, and the optimum ratio between hardness (92A) and flexibility ensures excellent results even at moderate printing speeds.

Area of application
Dampening elements, shock absorbers, flexible hinges
Sports and protective equipment
Inserts, seals, flexible joints and belts
Components for robotics and automation
Functional prototypes with high elasticity and durability

PEBA (Polyether blockamide) is a versatile plastic that is highly resistant to many chemicals such as diluted acids, alkalis, salts, aliphatic hydrocarbons, alcohols, has oils and fats.
Therefore, it can be used flexibly for a variety of applications.
PEBA is less resistant to highly oxidizing acids, concentrated mineral acids and polar solvents such as ketones and esters.

Well resistant against:

Aqueous solutions: Diluted acids, alkalis, salts and salt solutions.
Alcohols and hydrocarbons: Aliphatic hydrocarbons (gasoline), alcohols.
Oils and fats: Mineral oils, fats, waxes.
Amines, organic acids

Attacked by:

Strong oxidizing media: Concentrated mineral acids (sulfuric acid, nitric acid), chromic acid
Polar organic solvents ketones, esters, chlorofluorocarbons (e.g. benzene, carbon tetrachloride).

PEBA is well resistant to many everyday and industrial media, but use in contact with highly oxidizing substances or polar solvents should be avoided as this may lead to swelling or decomposition.
