Benefits of FibreX PEEK+GF20
- Inherently flame resistant and self-extinguishing
- Long-term hydrolytic stability even above 250C
- Outstanding resistance to a broad range of chemicals, including automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
- Low smoke and toxic gas emissions
- Excellent dimensional stability with low heat creep, low and uniform coefficient of thermal expansion, giving PEEK highly reproducible part-to-part dimensions
- High thermal properties with a Tg of 143C, CUT of 260C, and Tm of 343
- PEEK is an advanced, ultra-high-temperature polymer. It is not intended for standard desktop FDM printers
- For greater print success, we recommend these choices:
- PEKK: Similar high-performance family with improved printability for many users.
- ULTEM™ (PEI): High heat performance and excellent strength. Often a more forgiving option than PEEK.
- PPS: Strong chemical resistance and dimensional stability. Typically easier to process than PEEK
Yes, you can. Our 750g reels fit within the size requirements of popular automated material management systems like the Bambu AMS, Creality CFS, and Anycubic ACE Pro. That means you can run 3DXTECH’s engineering-grade filaments in your favorite system.
Weights and dimensions are close estimates. However, the exact numbers may vary slightly. Multi-material management system (MMS) compatibility is based on dimensions for a variety of systems by different manufacturers.

FibreX PEEK+GF20
FibreX PEEK+GF20 (PolyEtherEtherKetone) is one of the highest-performance polymers in the world. In fact, it’s one of the highest-performance plastics ever invented. Now reinforced 20% with glass fibers, PEEK+GF20 has exceptional mechanical, thermal, and chemical resistance properties along with its low warp, increased stiffness, and improved dimensional stability. PEEK+G20 is a go-to material in some of the most demanding applications where failure is not an option.
PEEK is an advanced, ultra-high-temperature polymer that demands industrial printing conditions to achieve consistent results. Plan on a 360–450°C hot end, 120–160°C bed, and a fully enclosed, actively heated chamber (70–150°C) to control warping and ensure strong layer adhesion. Best practices also include thorough filament drying, slow print speeds, and reduced or disabled part-cooling fan. Most standard desktop printers can’t reliably maintain these conditions.
For greater success, we recommend these high performance filaments:
PEKK: Delivers similar “PEAK-family” performance benefits but is often considered more forgiving to dial in than PEEK, with improved layer bonding and reduced warping sensitivity in many setups. It’s a strong step toward PEEK-level capability without as much process difficulty.
ULTEM™ (PEI): A high-performance polymer that typically prints more predictably than PEEK while still offering excellent heat resistance and strength. It’s a great choice when you want industrial-level performance with a more manageable processing window.
PPS: Known for strong chemical resistance and dimensional stability, and it can be an easier path to consistent parts compared to PEEK. It’s a smart option for environments involving fuels, solvents, or harsh chemicals where reliability matters.
MADE IN THE USA
We manufacture all of our filaments in our 68,000 ft² manufacturing facility (located in Grand Rapids, Michigan) using state-of-the-art equipment and processes. Our goal continues to be to make the most innovative filaments on the market – targeting difficult end-use applications.
