Nylon absorbs moisture quickly, which affects extrusion, layer bonding, dimensions and surface quality. It must be dried before critical printing and protected continuously.
Why control moisture
- Water vapor creates bubbles.
- Flow becomes unstable.
- Layer strength falls.
- Dimensions drift.
Protection process
Dry the whole spool at a safe temperature, cool it and store in a sealed box with desiccant. Keep the spool protected during printing.
Verify
- Mass.
- Reference print.
- Layer strength.
| Stage | Control | Record |
|---|---|---|
| Storage | Sealed | Date |
| Drying | Temperature/time | Cycle |
| Printing | Protected spool | Profile |
| Verification | Reference part | Result |
Common engineering mistakes
- Printing wet nylon.
- Drying only the surface.
- Sealing a hot spool.
- Using PETG profile.
- No comparison print.
Buyer checklist
- Is the nylon dry?
- Is storage sealed?
- Is drying documented?
- Is the spool protected during printing?
- Is the part tested?
