As a intermediate loading glass fiber reinforced nylon, it’s much improved in mechanical strength, rigidity, modulus, etc comparing to pure nylon filament.

Availability: In stock SKU: 50975


The printing consumables developed based on nylon 6/66 copolymers are added with 25% glass fiber, which greatly enhances the strength and rigidity of nylon, and can be used as a substitute for metal in many occasions; self-lubricating and wear-resistant properties make it suitable for printing gears; strong Toughness and impact resistance, can be used to print durable parts; high temperature resistance, heat distortion temperature up to 120 ℃; low shrinkage, not easy to warp and crack during printing, the surface of the printed items is matte.

Print recommend Drying at 70℃/>12h, using hardened steel, ruby ​​nozzle

1. ePA-GF needs to be dried (70℃/>12H) before printing to achieve the best printing effect. It is recommended to use it with the eBOX cartridge when printing.
2. The ePA-GF line has strong rigidity and is not easy to bend. In the feeding pipe, excessive bending of the wire should be avoided as much as possible.
3. ePA-GF is very easy to grind nozzles and extruder gears. It is recommended to use hardened steel nozzles or ruby nozzles. If conditions permit, you can choose hardened steel extruder gears. If the printing time is long, the throat and nozzles need to be replaced.
4. It is recommended to set the skirt to make it better for taking the model from the forming plate.



Highly durable, flexible material.

Nylon has high impact and abrasion resistance; offering a high amount of tensile strength whilst also being a flexible material. It is one of the most heat-stable filaments, remaining unchanged in high temperature environments. 

It is hygroscopic, meaning that the filament will absorb moisture easily which will cause prints to warp and fail. This can be circumvented by keeping the filament in an air-tight, dry environment. Nylon can warp easily; depending on the printer and slicer used, some trial and error may be needed to prevent this. Printed items will degrade from UV radiation if left in sunlight for long periods of time.

Used for: Gears, Screws, and Cable ties.

Some manufacturers provide PA6 & PA12 Nylons, PA12 has increased moisture stability and is more resistant to moisture absorption. The same applies to Nylon 66 compared to Nylon 6.
