Drying Guide
How to Dry TPU Filament Correctly
TPU absorbs moisture quickly and benefits from controlled drying and dry-box feeding.
Key Points
- Use 45–55°C for 4–6 hours as a typical starting range.
- Avoid temperatures that can deform the spool or soften the filament.
- Feed directly from a dry box during long jobs when possible.
- Reduce stringing only after moisture and feeding conditions are controlled.
Practical Decision Process
Begin with the part requirement and the target printer. Record the filament condition, spool history, nozzle, build surface, temperature profile and expected production duration. Change one variable at a time so the result can be compared rather than guessed.
Drying recommendations are starting ranges, not universal certification values. Follow the product TDS, dryer instructions and spool temperature limits. Printer configuration, ambient humidity and print duration affect the final result.
Wholesale and Production Review
For a trial or wholesale program, define the material, quantity, destination, printer type and application before selecting colors. Confirm packaging, storage, technical documents and repeat-order requirements before scaling from sample evaluation to regular supply.

Free samples · Freight credit
Samples are free; the customer pays sample shipping. On the first wholesale order, 1,000 rolls or more receive a credit for 100% of the sample shipping paid. Below 1,000 rolls, the credit is proportional: sample shipping paid × first-order roll quantity ÷ 1,000.
Examples: 100 rolls → 10%; 250 rolls → 25%; 500 rolls → 50%; 1,000+ rolls → 100%.
