Owens Corning


Glass Fiber Reinforced Polyamide 6 Filament

GF30-PA6 was developed to meet the demands of the real world. GF30-PA6 is a reinforced PA6 nylon filament with 30% glass fiber that is up to 250% stronger than carbon fiber reinforced ABS.


Performance Attributes

Thermal Stability
Superior Strength
High Wear Resistance


Up to 250% stronger than common filaments, XSTRAND® GF30-PP AND GF30-PA6 ensure high performance and wear resistance in the most extreme conditions. Developed with superior durability, XSTRAND® products give you the ability to design and print parts on site in a fraction of the time at a fraction of the cost. Advantages include chemical and UV resistance, thermal stability, superior durability, easy to use, high performance, design flexibility and the ability to test solutions in real world conditions.

XSTRAND® products are designed to be compatible with most open Fused Filament Fabricated 3D Printers.

WARNING: When melted, XSTRAND® filament can be abrasive due to its glass reinforcement. Printing with XSTRAND® may reduce lifespan of brass nozzles and extruder driving wheels. It is advised to use hardened steel nozzles and extruder driving wheels.

IMPORTANT NOTICE: We recommend the use local exhaust ventilation equipped with HEPA filters to remove ultra-fine particles and/or carbon filters to remove VOCs on all 3D printers.

Nozzle Settings

Hardened steel nozzle is highly recommended to print XSTRAND® filaments. When melted, XSTRAND® filament can be abrasive due to its glass reinforcement. Using hardened steel nozzles and extruder driving wheels is advised.

Bed Components

  • Bed Temperature: 80 - 110°C
  • If printing on glass either use reinforced strapping packaging tape (ie: Scotch Extreme Tape) on the bed with a bed temperature around 30 - 50°C or use Wolfbite ultra for polypropylene from Airwolf.
  • It is recommended to use a thicker bed (1/4" to 3/8"), such as high density polyethylene plate as a printing surface, instead of a glass plate for bed temperatures 30 - 50°C.
  • For large flat surfaces, a raft is required to reduce warping. 5-8mm raft offset and an airgap of .16 - .18 are recommended for best results.

Storage and Drying

XSTRAND® filaments must be stored in a dark and temperate location. It is recommended that the product remain closed in its original packaging until use.

* IMPORTANT NOTE: GF30-PA6 is very sensitive to moisture. For optimal printing results, the product must be dried at least 4 hours in the oven at 80°C prior to use and stored in a dry, Pelican like case, even during printing.
