eSun eTPU-95A - Transluscent Blue - 1.75 - 1kg Filament

eSUN eTPU‑95A Filament – Technical Specifications

• Plastic Type – TPU (Thermoplastic Polyurethane, Shore 95A hardness)

• Plastic Diameter – 1.75mm

• Density (g/cm³) – 1.21

• Melt Flow Index (g/10min) – 1.2 (190°C / 2.16kg)

• Tensile Strength (MPa) – 35

• Elongation at Break (%) – ≥800%

• Flexural Strength / Modulus – N/A (material too flexible for standard flexural testing)

• Impact Resistance – High toughness, strong tear and wear resistance

• Filament Weight – 1kg spool

Suggested Print Settings

• Nozzle Temperature (°C) – 220 to 250

• Bed Temperature (°C) – 45 to 60

• Print Speed (mm/s) – 20 to 50 (slower speeds recommended for flexible materials)

• Nozzle Diameter – ≥0.4mm recommended

• Cooling Fan – 100% (helps with surface finish and dimensional stability)

• Extruder Type – Direct‑drive extruder strongly recommended – Bowden setups possible only at very slow speeds (~20mm/s)

• Drying Recommendations – Dry filament at 55°C for 4+ hours before printing for best results

Key Features

• Excellent elasticity – parts resist deformation and bounce back after stress

• High wear and tear resistance – suitable for demanding mechanical applications

• Stable dimensional tolerance – low warping, smooth feeding, minimal stringing

• Durable and resilient – withstands repeated bending and stretching

• Transparent blue finish – aesthetic flexibility for design projects

Applications

• Shoe soles and insoles

• Watch straps and phone cases

• Medical prosthetics and orthotics

• Shock‑absorbing pads and seals

• Automotive and machinery flexible parts

• Sporting goods and protective gear

• Conveying pipelines and industrial components

Packaging

• Supplied on 1kg spool

• Vacuum‑sealed with desiccant for moisture protection

• Compatible with most FDM printers capable of handling flexible filaments

This filament is ideal for functional, flexible parts that need durability and resilience. It prints more easily than softer TPE (83A) but still requires careful handling (slow speeds, direct‑drive extruder preferred).
