This type of Flexfill is based on polyether-block-amide (PEBA), which was specially developed for processing by 3D printing. Although it is flexible with hardness 90 Shore A, it exhibits different thermal, mechanical, and chemical behavior from other Flexfill filaments (TPU, TPE)!

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

Working temperature:	225–245 °C
Heated bed:	70–90 °C
Diameter:	1.75 mm
Diameter tolerance:	+/- 0.10 mm
The length of the filament:	15 m
Available Spool variants:	Flexfill PEBA 90A "Natural"

3D Printing Guide
Webinars
The use of a direct drive extruder is highly recommended
For proper printing of flexible material with higher speed and quality, buy an appropriate printing device
For good adhesion use LockPAd, eventually on other bed types PVA glue or Magigoo PA
Moisture sensitive – keep in a protective resealable sachet
Drying filaments before processing
