eSun eTPU-95A 3D Printer Filament, 1.75mm, Transparent Red, 1kg

The eSun eTPU-95A 3D printer filament is a high-performance thermoplastic polyurethane material engineered for flexibility and durability. With a Shore hardness of 95A, this 1.75mm filament provides a balance between soft elasticity and structural integrity, making it a versatile choice for various additive manufacturing applications. The transparent red finish adds a distinct aesthetic quality to printed objects, while the material ensures consistent flow and reliable layer bonding during the printing process.

Advantages

This filament stands out due to its excellent mechanical properties, including high tear resistance and abrasion resistance. Its flexibility allows for the creation of parts that can bend or compress without breaking, which is essential for functional engineering components. The material is designed to minimize clogging and ensure a smooth extrusion experience, contributing to high-quality surface finishes and dimensional accuracy in finished prints.

Suitable for

• Flexible gaskets and seals
• Protective covers and cases
• Vibration dampeners
• Custom footwear components
• Flexible hinges and joints

When it may not be suitable

This material is not recommended for applications requiring high rigidity or structural load-bearing capabilities where deformation is undesirable. It may also be challenging to print on 3D printers with Bowden-style extruders due to the flexible nature of the filament, which can lead to buckling if the filament path is not well-constrained.

Key specifications

• Material: Thermoplastic Polyurethane (TPU)
• Shore Hardness: 95A
• Diameter: 1.75mm
• Weight: 1kg
• Color: Transparent Red

How to use

To achieve optimal results, ensure your 3D printer is equipped with a direct-drive extruder, which is generally preferred for flexible materials. Load the filament into the printer and adjust the temperature settings according to the manufacturer's recommendations for TPU. It is advisable to print at a slower speed to prevent the filament from tangling or slipping in the extruder gears. Ensure the build plate is properly leveled and consider using a brim or raft if adhesion issues occur with the print bed.

What to consider before purchase

• Check if your 3D printer extruder is compatible with flexible filaments.
• Verify the required printing temperature range for your specific printer model.
• Ensure your printer's slicer settings are adjusted for TPU, particularly regarding retraction and print speed.
• Store the filament in a dry, cool place to prevent moisture absorption.

Usage recommendations: For the best print quality, keep the filament in a sealed container with desiccant when not in use, as TPU is hygroscopic and can absorb moisture from the air, which may affect print performance.
