TPU-64D White elastic filament 1.75mm 1Kg eSun

The TPU-64D filament from eSun is a specially developed high-performance filament for 3D printers, impressing with its high hardness and elastic properties. With a Shore hardness of 64D, it is suitable for models that need to be particularly robust yet flexible. The modified composition ensures a lower processing temperature, uniform filament thickness, and a smooth surface during printing. This significantly reduces the risk of printing issues such as clogs or uneven flow. The material is resistant to oil, chemicals, and aging, making it especially durable and versatile. It also exhibits high impact resistance, allowing functional parts to be used reliably in everyday life. Since TPU absorbs moisture from the air, proper storage is crucial to ensure optimal print quality. Therefore, the filament should be dried in a dry box at 60–80 °C for 4–8 hours before printing. A short-feed extruder is recommended to increase the success rate in printing. The filament is suitable for complex models as it combines high detail precision with flexibility. Overall, TPU-64D is the ideal choice for users who need a robust, elastic, and reliable material.

Recommended Accessories:

• Filament Dry Box
• Filament Vacuum Set Pro 3 eVacuum by eSun

Hardness Comparison of Various TPU/TPE Materials:

• 83A (TPE) = very soft and rubber-like
• 87A (TPU) = soft to medium-hard, pleasantly elastic
• 95A (TPU) = medium hardness, still flexible and flexible
• 64D (TPU) = very hard, almost like a rigid plastic with residual flexibility

Properties:

• High hardness and elasticity allow for durable, yet flexible components.
• Good chemical and oil resistance ensures parts can be used in challenging environments.
• Excellent impact resistance increases the life span and stability of functional parts.
• Optimized processing temperature prevents excessive softening and facilitates printing even with complex geometries.
• High aging and UV resistance ensures long durability without significant material fatigue.
• Very good surface quality due to uniform filament thickness and low bubble formation with proper drying.
• Easy printability even at higher speeds up to 200 mm/s.

Handling TPU-64D:

• Moisture absorption: TPU quickly absorbs moisture from the air, leading to bubble formation, stringing, and rough surfaces. Therefore, the filament should be stored in a dry box (below 15% humidity) immediately after opening.
• Drying when wet: If the material has become wet, it should be dried in a dry box at 60–80 °C for 4–8 hours to restore print quality.
• Extruder choice: High-hardness TPU like 64D can be processed with Bowden extruders, but a direct extruder (short-range extruder) is recommended for higher success rates.

Application Examples
