PA (Nylon)
Polyamide (PA6 / PA12)
Nylon is the toughest, most durable common filament. It offers exceptional layer adhesion and impact strength, but is the most demanding to print, requiring mandatory drying, active dry-box feeding, high temperatures, and an enclosure, with moderate warping, shrinkage, and moisture sensitivity that make it unsuitable for beginners.
Ease of use: Very hard
This filament is demanding to print. Worth watching: it can be very moisture-sensitive and low on heat resistance.

Things to watch
- Can warp on large or sharp-cornered prints
- Extremely thirsty, keep it sealed with desiccant and dry it right before printing
- Softens in heat, not for hot cars or near heat sources
- Shrinks as it cools, which can affect dimensional accuracy
- Fussy about bed adhesion, use a brim, glue, or a textured plate
Strengths
- Solid strength for everyday parts
- Resists oils, solvents, and chemicals
- Wear-resistant for moving and rubbing parts
- A little give without being floppy
- Layers bond strongly for clean, watertight prints
- Food-safe potential with the right setup
