The R3D PEBA 90A Filament is designed for flexible, tough, and impact-resistant 3D-printed parts. With high elongation, strong layer bonding, and a soft 90A feel, it is ideal for protective components, flexible prototypes, wearable-style parts, shock-absorbing designs, soft grips, and functional elastic applications.
Flexible 90A Performance
Provides a soft yet durable feel for elastic parts, protective pieces, and flexible functional designs.
High Elongation Capacity
Offers over 550% elongation at break, making it suitable for parts that need bending, stretching, or repeated movement.
Strong Impact Resistance
Delivers 16 kJ/m² impact strength for printed components that need toughness in everyday use.
Reliable Layer Bonding
Provides strong interlayer adhesion, helping flexible parts maintain better structure and durability.
Not Recommended for AMS
Designed for direct or compatible flexible-filament feeding systems; AMS use is not recommended according to the TDS.
Printing Tips
| Setting | Recommendation |
| Nozzle Temperature | 210–240°C |
| Bed Temperature | 35–65°C |
| Build Surface | BuildTak®, glass, blue tape, or PEI |
| Cooling Fan | 10–100% |
| Printing Speed | Up to 200mm/s |
| Retraction Speed | 15–30mm/s |
| Nozzle Compatibility | 0.4–0.8mm nozzle, hardened steel or stainless steel |

For best results, print with a flexible-filament-compatible extruder and keep the filament path stable. Slower speeds and careful retraction settings can help reduce feeding issues. Dry the filament before printing if it has absorbed moisture.
FAQs
Q1: What is PEBA 90A best used for?
A: PEBA 90A is suitable for flexible prototypes, protective parts, soft grips, shock-absorbing pieces, wearable-style components, and functional elastic designs.
Q2: Is PEBA 90A flexible?
A: Yes. It has a 90A flexible material profile and offers over 550% elongation at break, making it suitable for parts that need bending or movement.
Q3: Can I print PEBA 90A with AMS?
A: No. PEBA 90A is not AMS compatible. Use a suitable flexible-filament feeding setup instead.
Q4: Is PEBA 90A easy to print?
A: It requires more care than PLA or PETG. A direct-drive or flexible-filament-compatible extruder is recommended, along with stable feeding and controlled print speed.
Q5: Should I dry PEBA 90A before printing?
A: If the filament has absorbed moisture, drying at 70°C for 8 hours is recommended before printing.
