Filament Management

Dry, load, and protect the filament path

Keep one dry spool in the DryBox and a smooth PTFE path.

1. Dry new or suspect spools

   Dry each new spool for 6 hours at 60 C before production, then let it cool for 4 hours before printing. Re-dry stored spools only when needed, at most once per week.

2. Keep one dry spool in the DryBox

   Keep only one spool inside and keep DryBox humidity below 20 percent.

3. Use heat and desiccant together

   Desiccant maintains low humidity between drying cycles. It does not replace the 6-hour, 60 C drying cycle, and active heat should not run while printing.

4. Prepare the filament before loading

   Cut the tip diagonally. Preheat before load or unload. Pull TPU out while it is still warm.

5. Protect the feed path

   Keep the PTFE path smooth. Avoid crushed tubing, hard bends, and unapproved material.
