WHY CARBONX PEEK+CF10
8,100 MPa Modulus. 265°C HDT. Hardened Nozzle Required.
CarbonX™ PEEK+CF10 is 3DXTech’s carbon fiber reinforced PEEK — 10% high-modulus chopped carbon fiber delivers 2× the stiffness of unfilled PEEK with a 265°C heat deflection temperature. For aerospace, automotive, defense, and semiconductor applications where maximum performance is mandatory.
2× Stiffer Than Unfilled PEEK
10% high-modulus CF raises tensile modulus from ~3,600 MPa to 8,100 MPa. Dramatically reduced creep and deflection under sustained load at elevated temperatures.
265°C HDT
Heat deflection temperature at 0.45 MPa. One of the highest HDT values achievable in any FFF filament. Parts maintain structural integrity at temperatures that would deform most engineering thermoplastics.
Near-Zero Moisture Absorption
PEEK+CF10 absorbs virtually no moisture — dimensional stability is maintained in humid or wet environments without conditioning. Critical for precision instrumentation and semiconductor tooling.
Made in USA
Extruded and wound in-house at 3DXTech’s Grand Rapids, MI facility under ISO 9001:2015 certification. Full lot traceability throughout filament fabrication.
PRINTING WITH CARBONX PEEK+CF10
PEEK+CF10 — Carbon Fiber Reinforced for Extreme Performance
CarbonX PEEK+CF10 requires a hardened steel nozzle — standard brass will wear rapidly against the carbon fiber. Beyond nozzle requirement, process is similar to unfilled PEEK: industrial hardware, 400°C-capable hot end, and heated chamber deliver reliable results.
- Extruder Temp 380–410°C — all-metal hot end required
- Bed Temp 140–165°C — PEI or garolite build surface
- Chamber Temp ≥70°C recommended — heated enclosure strongly recommended
- Nozzle Hardened steel ≥0.4mm — MANDATORY. Standard brass nozzle will wear rapidly against CF.
- Drying 120°C / 4 hr minimum before every print session
- ⚠ Nozzle Warning Hardened nozzle is non-negotiable. Carbon fiber reinforcement is highly abrasive — a standard brass nozzle will show measurable wear within a single 500g spool. Use hardened steel, ruby, or sapphire nozzle. 0.4mm minimum diameter — small nozzles are more prone to CF bridging.
THERMAL DATA
265°C HDT — Highest Heat Deflection in the Filament Catalog
Four thermal milestones defining CarbonX™ PEEK+CF10’s operating envelope — verified against 3DXTech CarbonX CF PEEK TDS v3.
HDT at 0.45 MPa. The highest heat deflection temperature achievable in the 3DXTech filament catalog. Carbon fiber reinforcement raises HDT from ~140°C for unfilled PEEK to 265°C — approaching PEEK’s own melting point of 343°C.
Tg of the PEEK matrix. Semi-crystalline structure means significant stiffness is retained well above this point due to the crystalline phase and CF reinforcement — the 265°C HDT demonstrates this directly.
Estimated continuous-use temperature based on HDT performance and PEEK crystallinity. Carbon fiber reinforcement significantly extends practical use temperature above unfilled PEEK’s ~150°C.
Required before every session. Despite near-zero moisture absorption, consistent drying ensures print quality at 380–410°C extrusion temperatures. Pre-drying is best practice for all PEEK-family filaments.
CHEMICAL RESISTANCE
Exceptional Chemical Resistance Retained With CF Reinforcement
CarbonX™ PEEK+CF10’s PEEK matrix delivers the same broad chemical resistance as unfilled PEEK — with added resistance to dimensional creep under chemical exposure due to the CF reinforcement. Resistant to virtually all organic solvents, fuels, hydraulic fluids, and industrial process chemicals.

WHERE IT WORKS
Where CF-Reinforced PEEK Outperforms Every Other Option
When unfilled PEEK isn’t stiff enough, dimensionally stable enough, or thermally capable enough — CarbonX PEEK+CF10 delivers.
Aerospace
Structural brackets, ducting, and load-bearing components requiring 2× the stiffness of unfilled PEEK at temperatures up to 250°C.
Semiconductor
Precision tooling, wafer handling equipment, and process hardware requiring dimensional stability (low CTE), chemical resistance, and near-zero moisture absorption in cleanroom environments.
Automotive
High-temperature under-hood components, structural brackets, and sensor housings where thermal expansion must be minimized.
Defense
Ballistic and structural components requiring maximum stiffness and thermal performance; low smoke / inherent flame resistance.
Oil & Gas
Downhole tools, valve components, and manifolds requiring combined chemical resistance, stiffness, and high-temperature performance.
Medical/Industrial Tooling
Sterilizable fixtures, jigs, and end-use device components requiring elevated stiffness and dimensional precision.
MATERIAL CARE
Moisture Is the Enemy. A Proper Protocol Eliminates It.
PEEK+CF10 has near-zero moisture absorption — the carbon fiber does not change this behavior. However, the PEEK matrix still requires consistent drying before printing at 380–410°C. Follow this protocol every session.
Dry Before Every Session
120°C minimum / 4 hours minimum. No exceptions — even a sealed spool that has been open for a few days benefits from a fresh drying cycle.
Print From the Dryer
For best results, print directly from a heated dry-box or dryer system. Ambient humidity will re-absorb into the filament during extended print runs.
Store Sealed With Desiccant
Return unused filament to an airtight bag or container with fresh desiccant immediately after printing. Long-term storage in original sealed packaging is acceptable.
Recognize Wet Filament Symptoms
Popping or crackling during extrusion, rough surface texture, reduced layer adhesion, and visible bubbling in the melt are signs of moisture contamination. Re-dry and restart.
HOW IT COMPARES
CarbonX™ PEEK+CF10 vs. Commonly Evaluated Alternatives
Buyers evaluating CarbonX PEEK+CF10 typically compare against unfilled ThermaX PEEK for a more ductile option, CarbonX PEKK-A+CF15 for a slightly higher CF loading in a different polymer, and Stratasys CF PEEK for a platform-locked alternative.

FREQUENTLY ASKED
CarbonX™ PEEK+CF10 — Buyer Questions Answered
What is CarbonX™ PEEK+CF10?
CarbonX™ PEEK+CF10 is 3DXTech’s 10% high-modulus chopped carbon fiber reinforced PEEK filament. It is semi-crystalline, available in Black only, and delivers 8,100 MPa tensile modulus and 265°C heat deflection temperature. A hardened steel nozzle is mandatory — the CF reinforcement is abrasive and will rapidly wear brass nozzles.
What temperatures does CarbonX™ PEEK+CF10 require?
CarbonX™ PEEK+CF10 requires an extruder temperature of 380–410°C and a bed temperature of 140–165°C. A heated enclosure at ≥70°C is strongly recommended. Dry at 120°C for 4 hours minimum before every print session. All-metal hot end rated to 410°C+ is required.
Why does CarbonX™ PEEK+CF10 need a hardened steel nozzle?
Carbon fiber is highly abrasive. A standard brass nozzle will show measurable wear within a single 500g spool of CF filament. Hardened steel, ruby-tipped, or sapphire nozzles all work. 0.4mm minimum diameter — smaller nozzles are more prone to CF bridging and clogging.
How does PEEK+CF10 compare to unfilled PEEK?
CF10 reinforcement approximately doubles tensile modulus (8,100 MPa vs. ~3,600 MPa for unfilled PEEK) and raises HDT from ~140°C to 265°C. Trade-off: elongation drops from ~35% to 3% — PEEK+CF10 is less ductile and more brittle than unfilled PEEK. Choose CF10 when stiffness and thermal performance outweigh toughness requirements.
What applications use CarbonX™ PEEK+CF10?
CarbonX™ PEEK+CF10 is used in aerospace structural brackets, semiconductor wafer handling tooling, automotive high-heat under-hood components, defense structural parts, and oil & gas downhole tools. Any application requiring maximum stiffness, 265°C thermal performance, and near-zero moisture absorption.
Is CarbonX™ PEEK+CF10 chemically resistant?
Yes. The PEEK matrix maintains full chemical resistance — the CF reinforcement does not affect the chemical compatibility profile. CarbonX™ PEEK+CF10 is resistant to virtually all organic solvents, fuels, hydraulic fluids, and industrial process chemicals. Consult the TDS v3 for specific fluid compatibility data.
How does CarbonX™ PEEK+CF10 compare to Stratasys CF PEEK?
Both use 10% CF-reinforced PEEK chemistry with similar performance targets. Stratasys CF PEEK is platform-locked to Fortus/F900 systems. CarbonX™ PEEK+CF10 runs on any open-material machine with a hardened nozzle and 400°C+ hot end — same chemistry, fraction of system cost, no platform lock-in.
Should I choose PEEK+CF10 or PEKK-A+CF15?
CarbonX™ PEKK-A+CF15 has slightly higher fiber loading and modulus, with a higher Tg (158°C) and is often considered easier to print than PEEK. Choose PEEK+CF10 when the established PEEK chemistry is required (qualification, supply chain), or when maximum HDT (265°C) is the primary driver. PEKK-A+CF15 is typically lower cost and more printable on a wider range of machines.
