eSUN PEBA-90A White 3D Printing Filament 1.75mm 0.8kg

eSUN PEBA-90A White is a high-performance flexible PEBA thermoplastic elastomer filament for FDM 3D printing, supplied in 1.75mm diameter with a 0.8kg net weight. Its standout advantages are ultra-high resilience, low weight, excellent impact and fatigue resistance, and rapid shape recovery, with a maximum rebound of up to 70% for demanding cushioning, wearable, sports and flexible functional applications.

⭐ PEBA-90A stands out by combining flexibility, low weight and high energy return. With a density of only 1.01 g/cm³ and up to 70% rebound, eSUN states that it is around 15–20% lighter than TPU and can print more than three times faster than TPU at the same hardness.

📦 Product Information

🔹 Brand: eSUN

🔹 Product: eSUN PEBA-90A

🔹 Material: PEBA Polyether Block Amide

🔹 Material Type: High-performance flexible thermoplastic elastomer

⭐ Why Choose eSUN PEBA-90A?

🔹 Maximum rebound up to 70% for strong cushioning, rapid shape recovery and significant energy return.

🔹 Low density of 1.01 g/cm³; eSUN states that PEBA is approximately 15–20% lighter than TPU for lightweight flexible parts.

🔹 Excellent fatigue resistance for repeated bending and compression without rapid permanent deformation or performance loss.

🔹 Excellent flexibility and impact resistance across a wide temperature range with strong resistance to low-temperature embrittlement.

🔹 eSUN specifies a broad operating adaptability range of approximately -40°C to 90°C.

🔹 At the same hardness, eSUN states that PEBA can print more than three times faster than TPU, with a maximum volumetric flow rate of 9 mm³/s.

🔹 Strong wear and abrasion resistance for repeatedly flexed functional components.

🔹 Good chemical resistance to automotive oils including gasoline, diesel and engine oil according to the TDS.

🔹 White has a soft warm off-white appearance with a subtle ivory tone.

🖨️ Printer Compatibility

Compatible with FDM printers that support 1.75mm flexible filament and nozzle temperatures up to 260°C, including printers from:

🔹 Bambu Lab

🔹 Creality

🔹 Prusa Research

🔹 Anycubic

🔹 ELEGOO

🔹 AMS and similar systems do not support, so use of a Direct Drive setup or a short, low-resistance feed path to achieve more stable extrusion with flexible filament.

⚙️ Printing Settings

🔹 Nozzle Temperature: 230–260°C

🔹 Recommended Nozzle Temperature: 240°C

🔹 Build Surface Temperature: 60–90°C

🔹 Fan Speed: 10–50%

🔹 Printing Speed: 25–110 mm/s

💡 Recommendations and Conditions of Use

🔹 Drying: 70–75°C for 6–8 hours before printing.

🔹 eSUN recommends re-drying the filament after prolonged exposure to air.

🔹 Use a low-resistance filament feeding system because excessive spool resistance may cause under-extrusion or inconsistent feeding.

🔹 eSUN recommends using a clean hotend and avoiding a hotend previously used with fiber-reinforced filament.
