XSTRAND™ Glass Fiber Polypropylene is an engineering grade 3D printing filament is developed by Owens Corning, a world leader in glass fiber composites.
Key filament attributes:
- Reinforced PP filament with 30% glass fiber
- Up to 250% stronger than ABS (Tensile Modulus (MPa) ISO 527)
- Designed for functional prototyping and industrial applications
- Excellent layer adhesion and reduced warping effect compare to neat materials
- Very stiff and strong materials
- Large operational temperature range -20°C to 120°C Good chemical and UV resistance
Filament diameter: 2.85mm
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™ is an abrasive filament due to its glass reinforcement. For this reason we recommend using a steel hardened nozzle when printing with this material.

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 Ultimaker, 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?
