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



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.


Market Applications


Manufacture on demand with XSTRAND® filaments. XSTRAND® filaments makes it possible to design, print, and make modifications to parts and tools on site. XSTRAND® GF30-PA6 ensures high performance, thermal stability and wear resistance for all your manufacturing and prototyping needs.

Industry and Tooling


Quick prototyping, testing, and custom design with an industrial grade material. Customize small scale production for new parts or rapidly prototype parts for testing.

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.

Frequently Asked Questions (FAQ)

What is the optimal print temperature?

  • PA - 240 - 260°C
  • If using adhesive solution (packaging tape, HDPE bed, etc.), much lower in the range of 30-50°C

What are the applications for the material?

  • Industrial usage including tools, fixtures, heavy duty replacement parts.
  • Sport and leisure parts.
  • Electronics and appliance parts, and many others.

How quickly does it degrade your hardened nozzle - e.g. how many grams printed before replacement?

  • On the ulti-maker, we have 2,432 hours of successful prints with GF-30 PP and GF-30 PA6 using the same tool steel nozzle.

What is the difference in surface finish between the two XSTRAND® GF-30 PP and GF-30 PA?

  • The GF-30 PA6 feels a little rougher and the GF-30 PP is silkier.

How much temperature can the printed part handle? Wet or dry?

  • This is linked to the Heat Temperature Deflection Test. We chose the highest ISO standard value at 1.8MPa and both materials standard specimen is handling 120°C in temperature. For this standard test, material are conditioned 48h at 23°C and 50% moisture air before the test. However, this is a general value that is totally dependent to the part geometry.

How is XSTRAND® filaments different than carbon fiber filled PA or PP?
