Frequently Asked Questions

How to ensure good bed adhesion for eSUN eFlex TPU?

For optimal bed adhesion with eSUN eFlex TPU, ensure your print surface (e.g., PEI, glass with adhesive) is clean and level. Use a bed temperature of 50-60°C and apply a thin layer of glue stick or a dedicated flexible filament adhesive. Printing a brim can also significantly improve first-layer success, preventing warpage and detachment.

What print speed is recommended for eFlex TPU filament?

Due to its flexibility, eFlex TPU performs best at slower print speeds. Start with speeds around 20-30 mm/s to minimize extrusion issues like stretching or jamming in the hotend. Adjust retraction settings carefully, using minimal retraction distance and speed, to prevent clogs and ensure smooth filament flow throughout the print process.

Is eSUN eFlex TPU susceptible to moisture absorption?

Yes, like most TPU filaments, eSUN eFlex TPU is hygroscopic and can absorb ambient moisture, which degrades print quality and mechanical properties. Store the filament in a dry, airtight container with desiccant when not in use. If moisture is suspected, dry the spool in a filament dryer at 50-65°C for 4-6 hours before printing.

What are the best post-processing techniques for eFlex TPU parts?

eFlex TPU parts generally require minimal post-processing. Supports can be carefully removed with flush cutters; heating the area slightly can aid removal. Sanding is possible for surface refinement, but TPU's elasticity might make it challenging. Chemical smoothing is generally not recommended as it can compromise material properties.
