Nylon (PA) filament is one of the most rewarding engineering materials — and one of the most punishing if you skip the basics. Follow this checklist and you'll print strong, wear-resistant parts instead of spaghetti.
The #1 rule: dry it, then keep it dry
Nylon absorbs moisture aggressively — a wet spool prints with bubbles, stringing and weak, brittle layers. Dry 8 h at 80 °C before printing (VOXFIL ships vacuum-sealed, so new spools are ready). Feed from a dry box or reseal immediately after each session.
Recommended settings for VOXFIL PA
| Parameter | Value |
|---|---|
| Nozzle temperature | 250–270 °C (260 °C sweet spot) |
| Bed temperature | 60–80 °C, PEI or glue stick |
| Print speed | 30–60 mm/s |
| Cooling fan | 10–30% (low) |
| Enclosure | Recommended for large parts |
| Drying | 8 h @ 80 °C, mandatory |
Adhesion without the fight
- Use a glue stick on PEI/smooth plates — nylon bonds aggressively to bare PEI
- Print a brim on tall or small-footprint parts
- Bed at 60–80 °C; too hot causes elephant's foot, too cold causes lifting
Fixing the three classic nylon failures
- Bubbles/hissing → wet filament. Dry 8 h at 80 °C, don't skip.
- Stringing → dry + lower cooling + tune retraction 1–2 mm.
- Warping/cracking → raise chamber temp, slow down, add a brim.
Nylon vs nylon-CF
Plain PA is tough and fatigue-proof — ideal for gears and living hinges. PA-CF adds stiffness and dimensional stability for drone frames and brackets. Same drying discipline, different end use.
