TPU-95A

eSUN TPU-95A Filament — High Flexibility & Superior Durability

eSUN TPU-95A features good flexibility with a hardness of 95A, is easy to print, and can quickly print large, complex, and accurate prototypes of elastomer parts. It offers excellent elasticity, and printed products with TPU filament are not easy to deform.

Key Features:

• Strong and Durable: Delivers exceptional wear and tear resistance, ensuring your 3D printed parts remain tough and intact even under heavy daily use
• Elastic and Soft: Features excellent flexibility and rebound resilience—it can easily bend and stretch while perfectly maintaining its original shape
• High Speed Printing: Specially optimized for smooth and consistent extrusion, enabling fast and stable printing without clogging or compromising quality

Specifications:

• Brand: eSUN
• Product: TPU-95A
• Diameter: 1.75mm
• Net Weight: 1KG/Spool
• Hardness: 95A

Physical Performance: Density 1.21 g/cm³, Melt Flow Index 1.2 g/10min (190°C/2.16kg).

Mechanical Properties: Tensile Strength 29.63 MPa (XY) / 4.43 MPa (Z), Elongation at Break >400% (XY) / 35.66% (Z).

Recommended Printing Parameters: Extruder 220–250°C, Bed 45–60°C, Fan Speed 100%, Printing Speed <100 mm/s, Heated Bed required. Dry at 55°C for >4h, direct-drive extruder recommended, slow printing.

Notes:

• Flexible materials are relatively soft and more prone to deforming at the extruder gears; lower the printing speed to reduce extrusion deformation
• Flexible materials have poorer cooling performance, reducing overhang and bridge effectiveness; adding supports is highly recommended
• Direct-drive printers are recommended for best results
• TPU is highly hygroscopic; if left unused for an extended period, dry at 60°C for more than 8 hours before printing
• Residue may build up in the nozzle during long print runs; use cleaning filament or replace the nozzle and throat tube if necessary
