NylonG
NylonG is a glass fiber reinforced nylon 3D printing filament which boasts incredible impact resistance and also impressive tensile strength. For makers looking to create with engineering grade materials or those in need of ultra high-performance nylon - this filament delivers.
Nylon G also comes in a black, white, red, blue, grey, orange, tan and olive green.
NylonG features glass fiber reinforcement which reduces the amount of flex in the base nylon. This means that printed parts under stress will hold their shape better, retaining dimensional accuracy. The glass fiber specifically adds much more impact resistance to printed parts, making this filament great for parts that take a beating. Popular in aerospace development and testing, glass fiber reinforced materials can absorb large amounts of energy while maintaining shape and structural integrity.

Additional Recommendations
G10 FR4 heated bed is preferred for printing surface.
Make sure to achieve a good first layer.
Might need to use a brim to increase adhesion.
Prints with a grainy texture but prints very well.
