Description

eSUN Flex TPU 87A filament is engineered as a transparent, soft, and highly elastic material, offering superior flexibility and exceptional mechanical properties including high flexural tensile resistance, wear resistance, and anti-aging characteristics. This material exhibits remarkable chemical resistance to water, oils, and various solvents, making it suitable for durable functional parts. Additionally, it provides waterproof, cold-proof, and anti-ultraviolet features, extending its application versatility.

Achieving successful prints with flexible filaments like eSUN Flex TPU requires careful printer calibration and attention to settings. It is crucial to ensure proper bed adhesion and consider slower print speeds, as well as a direct filament path to the extruder to prevent buckling. While compatible with most FDM 3D printers, optimal results are achieved on machines specifically designed or modified for flexible material handling, ensuring consistent extrusion and precise layer bonding for resilient final products.

Frequently Asked Questions

What printing considerations are important for eSUN Flex TPU 87A?

Printing flexible filaments like eSUN Flex TPU 87A requires a direct drive extruder setup and slower print speeds, typically 20-40 mm/s, to prevent tangling and material compression. Ensure retraction settings are minimal to avoid clogs. Keep the filament path smooth and free of sharp bends for consistent extrusion.

How can I ensure good bed adhesion with eSUN Flex TPU 87A?

Optimal bed adhesion for eSUN Flex TPU 87A is achieved with a heated bed set between 80-90°C. Using an adhesive, such as a PVA-based glue stick or Kapton tape, significantly improves first-layer grip. Calibrate your Z-offset carefully to ensure the initial layer is slightly compressed without squishing too much.

Is it necessary to dry eSUN Flex TPU 87A filament before printing?

Yes, TPU is hygroscopic and absorbs moisture from the air, which can lead to poor print quality, bubbles, and weak layer adhesion. It's highly recommended to dry eSUN Flex TPU 87A at 55-65°C for at least 6-8 hours before printing, and ideally, store it in a dry box.

What are the best practices for storing eSUN Flex TPU 87A?

To maintain the material's properties and prevent moisture absorption, store eSUN Flex TPU 87A in an airtight container or a resealable bag with desiccant packets immediately after use. This helps preserve print quality, minimizes material degradation, and ensures the filament is ready for future prints without additional drying.
