Nylon (PA) print settings

The toughest common filament — but it drinks water out of the air and must be printed dry.

Enclosure: Expect warping, splitting layers or failed prints without one.

Bed surface & adhesion

Garolite (G10) is the classic answer; PEI with a glue stick also works.

Retraction starting points

Dry the filament first — with these, stringing is far more often moisture than retraction, and no retraction value fixes a wet spool.

Good for

• Living hinges, gears and bushings — it is self-lubricating
• Impact loads that would shatter PLA or crack PETG

Watch out for

• Dry it before every print — wet nylon pops, foams and prints weak
• Absorbs moisture in hours, not days; print from a dry box
• Highest shrinkage here — dimensional accuracy needs compensation

Other filaments

These are widely-published starting points for the generic material, not a specification. Individual spools vary by brand, colour and additive package — always defer to the figures printed on your spool.
