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.

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.

Frequently Asked Questions (FAQ)

What is the optimal print temperature?

  • PP - 250 - 280°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?
