3DXTech compounds CarbonX PEEK+CF10 in Grand Rapids, Michigan at its 68,000 sq ft facility, with published print and material data — no mystery filament. Rev1 Technologies is your authorized 3DXTech reseller and US support partner, Auburn Hills, Michigan.
One of the highest-performance thermoplastics — reinforced.
PEEK is already one of the most capable engineering thermoplastics ever produced — and CarbonX PEEK+CF10 raises it further with 10% high-modulus chopped carbon fiber. The result is an ultra-high-temperature filament with exceptional stiffness, strength, and dimensional stability, plus excellent chemical resistance, near-zero moisture absorption, and low smoke and toxic-gas emissions. It is used in some of the most demanding applications in aerospace, automotive, defense, semiconductor, and oil-and-gas — the parts where failure is not an option. 3DXTech compounds it in the USA into consistent, printable filament so you can print true end-use PEEK components in-house.

Extreme stiffness that holds its shape when it gets hot.
A 265°C HDT and an 8100 MPa modulus, in a printable filament.
Carbon-fiber reinforcement gives CarbonX PEEK+CF10 an 8100 MPa tensile modulus — the stiffness engineers need to lightweight structural parts — while the PEEK base delivers a 265 °C heat-deflection temperature that keeps parts stable far beyond where ordinary filaments soften. Add excellent chemical resistance, a low coefficient of thermal expansion, and near-zero moisture absorption, and you have a material for functional end-use components that run hot, carry load, and see aggressive fluids.
Stiffness, heat, and chemical resistance at the top of the class.
CarbonX PEEK+CF10 is built for the most demanding structural, high-temperature applications. Numbers below are from the published TDS (Rev 3.0, ISO-tested, printed at 400 °C on a 0.4 mm nozzle, 100% infill).
High-modulus carbon fiber (ISO 527) — exceptional stiffness for structural, load-bearing parts.
Strength at break (ISO 527) — holds up under sustained mechanical load at temperature.
Rigid in bending (ISO 178) with an 8300 MPa flexural modulus — stiff, not floppy.
Deflection temperature at 0.45 MPa (ISO 75) — far above engineering nylons or PC.
DSC-measured Tg — comfortably above the service temperatures of most other polymers.
Measured per ASTM D257 — standard for the composition, informs ESD-sensitive use.
A true high-temp printer — hot end, hot bed, heated chamber.
This is an advanced material: it needs a genuine high-temperature printer with an actively heated, fully enclosed chamber. These are 3DXTech's recommended starting conditions — dry the filament first, print slowly, and purge the nozzle of PEEK at the end of every job.
Requires a genuine high-temp hotend rated for 400 °C-plus — not a standard all-metal hotend.
A high-temperature heated bed with a suitable adhesive for reliable first-layer grip on PEEK.
A fully enclosed, actively heated chamber controls warping and drives strong layer adhesion.
Use a hardened-steel nozzle — carbon fiber is abrasive and wears out brass fast.
Dry thoroughly at 120 °C for ~4 hours; keep dry for the best surface and strength.
Print slowly with the cooling fan reduced or disabled, and fully purge PEEK from the nozzle after printing.
End-use parts for the environments where failure is not an option.
Because it combines extreme heat resistance, high stiffness, chemical resistance, and near-zero moisture absorption, CarbonX PEEK+CF10 lands in the most demanding industries — printed in-house instead of machined from billet or waiting on injection tooling. These are the sectors 3DXTech calls out for this grade.
Matte carbon-fiber black — 1.75 mm, four reel sizes.
CarbonX PEEK+CF10 ships in a single, purpose-built color: a deep matte carbon-fiber black. Carbon fiber is inherently black — there are no other color options for this material. It's available in 1.75 mm on 250 g, 500 g, 1 kg, and 2 kg reels; choose your reel size in the buy-box, or ask us about the 2 kg special-order size and bulk pricing. 3DXTech's 750 g-class reels are sized to fit popular automated material systems — check the reel dimensions below against your printer.

FAQ
3DXTech CarbonX PEEK+CF10 — Common Questions
What kind of printer do I need?
A true high-temperature machine. CarbonX PEEK+CF10 prints at 380–410°C, so you need a genuine high-temp hotend, a high-temperature heated bed (120–160°C), a hardened-steel nozzle, and — critically — a fully enclosed, actively heated chamber at 70–150°C. Standard desktop FDM printers cannot run this material.
Why is a heated chamber required?
PEEK is semi-crystalline and highly temperature-sensitive as it cools. An actively heated chamber controls warping and drives strong layer adhesion — without it, large PEEK parts warp, crack, and delaminate. Unlike carbon-fiber nylon, a chamber is not optional for this grade.
Do I need a hardened nozzle?
Yes. The carbon fiber that gives this filament its stiffness is abrasive and will quickly wear out a standard brass nozzle. Use a hardened-steel or other abrasion-resistant nozzle, 0.4 mm minimum.
How should I dry it?
Dry the filament thoroughly at 120°C for about 4 hours before printing and keep it in a dry box. PEEK+CF10 has near-zero moisture absorption once dry, but drying before the first print gives the best surface finish and layer strength.
Any print tips for best results?
Print slowly, reduce or disable the part-cooling fan, and always fully purge PEEK from the nozzle at the end of a job so it doesn't carbonize on the next heat-up. Slicing at 0.25 mm layers or higher gives the most consistent flow with the filled filament. It ships matte black, 1.75 mm, on 250 g, 500 g, 1 kg, and 2 kg reels — the 2 kg is a special-order (MOQ) size.
Where does CarbonX PEEK+CF10 get used, and is it USA-made?
It lands in the most demanding sectors — aerospace, automotive, defense, semiconductor, and oil-and-gas — for end-use parts that run hot, carry load, and see aggressive chemicals, often printed in-house to replace machined metal or injection-molded PEEK. 3DXTech manufactures it at its 68,000 sq ft facility in Grand Rapids, Michigan, with published data and lot traceability.
