eSun PEBA 90A Flexible 3D Print Filament 800g 1.75mm
eSun PEBA 90A is a premium flexible filament designed for parts that need rubber-like flexibility + excellent rebound. Compared with typical TPU/TPE, PEBA is known for its livelier elasticity, fatigue resistance, and low-temperature performance, making it ideal for functional flexible parts that need to spring back repeatedly.
Key Features
-
90A flexible hardness (rubber-like feel with strong resilience)
-
High rebound / elastic recovery for repeated flexing
-
Fatigue & impact resistance – great for functional flexible parts
-
Good low-temperature performance (stays more flexible in cooler conditions vs many elastomers)
-
Smooth surface finish and strong interlayer bonding
Best For
-
Wearables & soft-touch parts
-
Flexible hinges, clips, latches
-
Shock-absorbing feet, bumpers, gaskets, dampers
-
Flexible brackets, cable strain relief, protective covers
-
Springs, compliant mechanisms, vibration isolation parts
Print Settings
- Nozzle temp: 220–250°C
- Bed temp: 40–60°C
- Print speed: 20–60 mm/s (start slower for reliability)
- Retraction: Minimal (direct drive: low; Bowden: very low / test carefully)
- Cooling fan: 30–80% (tune for bridging vs layer bonding)
- Bed adhesion: PEI / textured PEI often works well; use glue stick if needed
- Drying: Recommended if stringing/bubbles appear (store dry after opening)
