Overview
(Glass Fiber) GF-Nylon uses nylon 12 as a base; we use this material for the application of high wear. ie gears, sliding interfaces.
It shares many of the benefits of out CF-Nylon, but trades a bit of tensile strength for wear resistance and lubricity:
Low moisture absorption → Nylon Moisture Absorption Properties
Highly dimensionally stable
highly resistant to hydrocarbons, alkalis, fats, oils, fuel, ethers, esters, and ketones
Our GF-Nylon has been used for assembly jigging, power transmission gears, and wear bars.

FAQ
Is annealing needed or recommended:
Annealing is not recommended; it adds 3-4% in tensile strength and risks warping the part; you need to pack it in with sand/salt, and it's a massive pain for the benefits.
Is the base nylon 12
Yes

Common Limitations
The most significant faults of GF-Nylon are:
Nylon 12 has low surface energy, making painting more challenging
it has a lower print speed than our CF-PETG by about 35%
does not like thin walls, minimum 2.5 mm
