eSUN TPU-95A Blue 3D Printing Filament 1.75mm 1kg

eSUN eTPU-95A Blue is a high-performance flexible TPU filament for FDM 3D printing, supplied in 1.75mm diameter with a 1kg net weight. With Shore 95A hardness, it combines flexibility, resilience, abrasion resistance, tear resistance, impact resistance and bending endurance while maintaining good dimensional stability and shape recovery, in a deep saturated solid-blue tone.

⭐ eSUN eTPU-95A stands out by balancing flexible TPU behavior with Shore 95A firmness, providing reliable shape recovery and strong wear, tear, impact and repeated-bending resistance while remaining more controllable than softer TPU grades.

📦 Product Information

⭐ Why Choose eSUN eTPU-95A Blue?

🔹 Shore 95A flexibility provides a useful balance between elasticity, firmness and printing control.

🔹 Good resilience allows parts to bend and stretch before recovering their original shape.

🔹 Strong abrasion, tear and cut resistance for parts exposed to friction and repeated use.

🔹 Good impact resistance and vibration absorption for protective parts, dampers and flexible bumpers.

🔹 Excellent bending endurance for repeatedly flexed components.

🔹 Low shrinkage and good dimensional stability help produce accurate flexible parts.

🔹 Blue provides a deep saturated solid-blue appearance close to dark royal blue and is distinct from eSUN Translucent Blue.

🖨️ Printer Compatibility

Compatible with FDM printers that support 1.75mm flexible filament and nozzle temperatures up to 250°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: 220–250°C

🔹 Build Surface Temperature: 45–60°C

🔹 Fan Speed: 100%

🔹 Printing Speed: under 100 mm/s

💡 Recommendations and Conditions of Use

🔹 Pre-drying: 55°C for more than 4 hours for best printing results.

🔹 After prolonged moisture exposure, eSUN recommends drying at 60°C for more than 8 hours before printing again.

🔹 Direct Drive is preferred because flexible filament may deform in the extruder gears at excessive feed speeds.

🔹 Bowden systems may require speeds around 20 mm/s or lower for stable feeding.

🔹 Keep TPU dry in a sealed container with desiccant because the material is highly hygroscopic.
