PAHT
High-Temperature Polyamide / High-Temp Nylon
Nylon rated for higher temperatures with lower moisture absorption than PA.
Skill level: Advanced
This filament is tricky to print, strong and heat-resistant. Worth watching: it can be moisture-sensitive and a bit smelly to print.

Things to watch
- Can warp on large or sharp-cornered prints
- Soaks up moisture quickly, keep it sealed and dry before printing
- Gives off noticeable fumes, print with ventilation or filtration
- Shrinks as it cools, which can affect dimensional accuracy
- Fussy about bed adhesion, use a brim, glue, or a textured plate
Strengths
- Strong parts that hold up under load
- Handles heat well
- Resists oils, solvents, and chemicals
- Layers bond strongly for clean, watertight prints
- Prints clean with minimal stringing
