Flexfill PEBA 90A | Fillamentum
This type of flexible filament has different properties than the regular TPE, TPU filament you might be used using. Based on polyether-block-amide, PEBA was specially developed for use with 3D printers. Although it is flexible with hardness 90 Shore A (equivalent to 42 Shore D), it exhibits different thermal, mechanical, and chemical behavior than the other Flexfill filaments (TPE/TPU). It is resistant to cyclic loading without getting damaged and has a high energy return, and still has the lowest density of all the Flexfill filaments. These properties can be leveraged in the production of custom-made shoe outsoles or ski-boots outsoles. PEBA excels in very low-temperature resistance, where its mechanical properties are reliable until -60°C!

How to store filaments
Humidity and UV light can decrease the filament quality and weaken its mechanical properties. We strongly recommend storing open filaments in a dry and dark place. You can find a complete guide on how to properly store your filament here
Where to throw print fails and supports?
We kindly ask our customers to cope with plastic waste responsibly. Failed prints, support material, rafts, or brims should be liquidated according to the local guidelines. Paradoxically, in most cases, it is better to throw this waste in the regular trash can, as most of the material waste created in 3D printing is not identified, which causes more problems than benefits in the waste sorting facilities.

Fillamentum recommends using Magigoo PA as an adhesive (it is not a mistake, as PEBA contains amide) and we don't recommend printing on PEI surfaces. Regarding cooling, the more you cool, the more brittle the final part will be.
Features:
- Excellent mechanical properties
- Flexible even at low temperatures
- High reversible deformation
- Rebound resilience preserved also at low temperature (down to -60 °C)
- Great chemical resistance, for mention against car fluids (gasoline, diesel, oil, ...)
- Resistant to cyclic loading without obvious damage
- High energy return, low hysteresis
- Tear resistance
- The lowest density from flexible filaments
- Recyclable, BPA free
- Low fumes released
- Safe for food contact applications (declaration sent per request)
- Safe to use in electrical and electronic equipment
General information about PEBA :
This type of flexible filament has different properties than the regular TPE or TPU filament you might be using. Based on Poly(ether-block-amide), PEBA was specially developed for use with 3D printers. Polyamide (aka nylon) is a hard hydrophilic segment that is responsible for higher mechanical strength. On the other side polyether is a soft hydrophobic part that gives flexibility. Thus, it offers a balanced combination of mechanical strength, breathability, flexibility, chemical resistance, and ease of processing.

Who is Fillamentum for?
Choose PLA Extrafill when colour and surface quality matter – for models, prototypes and decorations. CPE HG100 is a tougher, easy-to-print alternative to PETG for functional parts. The Flexfill range covers flexible parts from soft to semi-rigid, and the nylon grades suit wear-resistant mechanical parts; remember to dry nylon before printing.
Frequently asked questions
Where is Fillamentum made?
Fillamentum is a Czech brand. Its filaments are exported to more than 62 countries around the world.
What is CPE HG100?
CPE is a copolyester related to PETG. It was developed for users who want more toughness than PETG while keeping easy printing with no warping.
Which Flexfill should I choose?
The number in the name is the Shore hardness: the lower the number, the softer and more elastic the part. Flexible filaments print best slowly, ideally with a direct-drive extruder.
