Nylon (PA) Print Settings and Common Problems

Nylon (PA) is strong and durable, but it's also the most moisture-sensitive material on this list by a wide margin. If you're having any quality issue with nylon at all, check drying before touching a single slicer setting.

Nozzle temp

240-270°C

Bed temp

70-100°C

Nylon absorbs atmospheric moisture faster than almost any other filament — sometimes within hours of being unsealed. Dry it before every print, and for long prints, consider feeding directly from a heated dry box rather than relying on pre-drying alone.

Common problems

  • Popping or crackling sounds while printing

    This is trapped moisture flash-boiling into steam as it hits the hot end — an unmistakable sign the filament needs drying, not a hardware problem. Dry the spool for several hours at the manufacturer's recommended temperature before trying again.

  • Stringing and oozing

    Wet nylon strings dramatically more than properly dried nylon at the same settings. Before adjusting retraction or temperature, dry the filament first — it's the more likely fix.

  • Poor bed adhesion

    Nylon doesn't stick well to standard surfaces without help. A dedicated nylon-safe adhesive, PVA-based glue stick, or a specific nylon bed surface makes a bigger difference here than on any other material on this list.

  • Weak, brittle layers

    Beyond moisture, nylon benefits from an enclosure and a heated chamber for larger parts — inconsistent ambient temperature during the print noticeably weakens layer bonding.
