3D printing flexible filament eSun eTPU-95A 1.75 mm, 1 kg, transparent orange

eSun eTPU-95A 1.75 mm flexible filament in transparent orange is a thermoplastic polyurethane (TPU) material formulated for FDM/FFF 3D printers. Supplied on a 1 kg spool, the filament offers high elasticity and good abrasion resistance suitable for parts that require repeated deformation and impact absorption. The transparent orange color provides visual appeal while allowing some light transmission through thin sections. Designed for printers that accept flexible filaments, this material requires specific print settings to achieve reliable extrusion and layer adhesion.

Advantages

The filament combines softness and resilience, enabling printed parts to stretch and return to shape without permanent deformation. Its abrasion resistance and tear strength make it appropriate for functional components exposed to mechanical stress. The 1.75 mm diameter ensures broad compatibility with many desktop FDM/FFF machines that support TPU-type materials. The transparent orange hue offers aesthetic versatility for prototyping and consumer products where partial translucency is desired.

Suitable for

• Gaskets and seals that require elasticity and compression recovery
• Wearable components and flexible straps
• Shock-absorbing elements and bumpers
• Flexible prototypes and functional test parts

Key specifications

• Material type: Thermoplastic polyurethane (flexible TPU)
• Diameter: 1.75 mm
• Spool weight: 1 kg
• Color: Transparent orange
• Mechanical properties: high elasticity, good abrasion resistance
• Print technology: FDM/FFF

How to use

Load the filament onto a printer compatible with flexible TPU materials and set filament diameter to 1.75 mm in the slicer. Use a direct-drive or suitably tuned Bowden extruder to reduce feeding issues, and configure retraction, print speed, and temperature according to the printer manufacturer’s guidelines for TPU. Typical adjustments include lower print speeds, reduced retraction distance, and optimized nozzle temperature to achieve consistent extrusion and layer adhesion. Bed adhesion aids such as a PEI sheet, glue stick, or blue tape can help secure the first layer. After printing, allow parts to cool before removing them from the build plate to reduce deformation.

Usage recommendations

For best results, start with conservative print speeds and small retraction settings, calibrate extrusion multiplier if necessary, and store the filament in a dry environment to prevent moisture absorption. Test print small samples to fine-tune temperatures and speeds for your specific printer setup.
