WHY CARBONX PEKK-A+CF15 [AERO]
9,125 MPa Modulus. 165°C Tg. Easier to Print Than CF PEEK.
CarbonX™ PEKK-A+CF15 is 3DXTech’s aerospace-oriented carbon fiber PEKK-A filament — 15% high-modulus chopped CF delivers 9,125 MPa tensile modulus, 285°C HDT, and inherent UL 94 V-0 flame resistance. PEKK-A’s 60/40 copolymer structure enables a lower, easier print window (360–390°C) than CF PEEK — with higher Tg and stronger mechanical performance.
Higher Tg Than CF PEEK (165°C)
PEKK-A’s 60/40 copolymer structure yields a 165°C glass transition — 22°C above PEEK’s 143°C Tg. Parts retain stiffness at temperatures where CF PEEK would begin to soften.
Easier to Print Than CF PEEK
360–390°C extrusion vs. 380–410°C for CF PEEK. Wider process window reduces the risk of degradation and makes PEKK-A+CF15 accessible on a broader range of industrial hardware.
Inherently UL 94 V-0
PEKK base resin is inherently flame resistant to UL 94 V-0 — not a coating, not an additive. Critical for aerospace, defense, and electrical applications where self-extinguishing behavior is specified.
Made in USA — AERO Grade
Extruded in Grand Rapids, MI under ISO 9001:2015 certification. CarbonX [AERO] is positioned for aerospace and defense supply chains requiring lot traceability and domestic manufacture.
PRINTING WITH CARBONX PEKK-A+CF15
PEKK-A+CF15 — Easier Process Window Than CF PEEK
CarbonX PEKK-A+CF15 requires a hardened steel nozzle — standard brass will wear rapidly against the carbon fiber. The 360–390°C extrusion window is notably wider and lower than CF PEEK’s 380–410°C, making it more accessible on industrial-grade open-platform printers. Heated bed and enclosure are required.
- Extruder Temp 360–390°C — all-metal hot end required (easier than CF PEEK’s 380–410°C)
- Bed Temp 120–140°C — PEI or garolite build surface
- Chamber Temp Up to 140°C recommended — heated enclosure strongly recommended
- Nozzle Hardened steel ≥0.4mm — MANDATORY. Standard brass nozzle will wear rapidly against CF.
- Drying 120–140°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 250g spool. Use hardened steel, ruby, or sapphire nozzle. 0.4mm minimum diameter — small nozzles are more prone to CF bridging.
THERMAL DATA
285°C HDT — Higher Tg and Easier Processing Than CF PEEK
Four thermal milestones defining CarbonX™ PEKK-A+CF15’s operating envelope — verified against 3DXTech CarbonX CF15 PEKK-A TDS v1.
HDT at 0.45 MPa. 20°C higher than CarbonX PEEK+CF10’s 265°C. The PEKK-A matrix’s higher Tg (165°C vs. 143°C) directly contributes to this superior heat resistance at load.
PEKK-A (60/40 copolymer) glass transition. 22°C above PEEK’s 143°C Tg — parts retain stiffness at temperatures where CF PEEK structures begin to soften. Significant advantage in elevated-temperature structural applications.
Estimated continuous-use temperature based on PEKK-A HDT and crystallinity. CF reinforcement extends practical use temperature well above unfilled PEKK-A’s capabilities.
Required before every session. Consistent drying at 120–140°C ensures print quality and prevents moisture-related extrusion defects at 360–390°C. Pre-drying is best practice for all PAEK-family filaments.
CHEMICAL RESISTANCE
Exceptional Chemical Resistance Retained With CF Reinforcement
CarbonX™ PEKK-A+CF15’s PEKK-A matrix delivers broad chemical resistance comparable to 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.

MATERIAL CARE
Moisture Is the Enemy. A Proper Protocol Eliminates It.
PEKK-A+CF15 requires consistent drying before printing at 360–390°C. Follow this protocol every session to maintain print quality and part properties.
Dry Before Every Session
120–140°C / 4 hours minimum. No exceptions — even a sealed spool that has been open for a few days benefits from a fresh drying cycle before printing.
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 at production temperatures.
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.

FREQUENTLY ASKED
CarbonX™ PEKK-A+CF15 — Buyer Questions Answered
What is CarbonX™ PEKK-A+CF15 [AERO]?
CarbonX™ PEKK-A+CF15 [AERO] is 3DXTech’s 15% high-modulus chopped carbon fiber reinforced PEKK-A (60/40 copolymer) filament. Available in Black only, it delivers 9,125 MPa tensile modulus, 285°C HDT, and inherent UL 94 V-0 flame resistance. Positioned for aerospace, defense, and industrial applications. A hardened steel nozzle is mandatory — CF reinforcement is abrasive and will rapidly wear brass nozzles.
What temperatures does CarbonX™ PEKK-A+CF15 require?
CarbonX™ PEKK-A+CF15 requires an extruder temperature of 360–390°C and a bed temperature of 120–140°C. A heated enclosure up to 140°C is recommended. Dry at 120–140°C for 4 hours minimum before every print session. All-metal hot end rated to 390°C+ is required.
Why does CarbonX™ PEKK-A+CF15 need a hardened steel nozzle?
Carbon fiber is highly abrasive. A standard brass nozzle will show measurable wear within a single 250g 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 PEKK-A+CF15 compare to PEEK+CF10?
PEKK-A+CF15 has a higher Tg (165°C vs. 143°C), higher HDT (285°C vs. 265°C), greater tensile modulus (9,125 vs. 8,100 MPa), much higher flexural strength (178 vs. 136 MPa), and inherent UL 94 V-0 flame resistance (PEEK does not carry this inherent rating for its CF variant). PEKK-A+CF15 also prints at lower temperatures (360–390°C vs. 380–410°C) and costs significantly less ($88 vs. $195 / 250g). For most applications, PEKK-A+CF15 is the stronger, more affordable, and more printable choice.
What applications use CarbonX™ PEKK-A+CF15?
CarbonX™ PEKK-A+CF15 is used in aerospace structural brackets and cabin interior components (UL 94 V-0 compliance), defense and military structural parts, semiconductor precision tooling, oil & gas downhole components, and automotive high-temperature structural applications. Any application requiring the combination of maximum stiffness, 285°C thermal performance, and inherent flame resistance.
Is CarbonX™ PEKK-A+CF15 UL 94 V-0 rated?
Yes — PEKK base resin is inherently UL 94 V-0 flame resistant. This is not a coating, additive, or external treatment. The flame resistance is built into the polymer chemistry and is retained throughout the printed part. This makes PEKK-A+CF15 uniquely suitable for aerospace, defense, and electrical applications where self-extinguishing behavior is a specification requirement.
How does CarbonX™ PEKK-A+CF15 compare to Stratasys CF PEKK?
Both use carbon fiber reinforced PEKK chemistry with similar performance targets. Stratasys CF PEKK is platform-locked to Fortus/F900 series machines. CarbonX™ PEKK-A+CF15 runs on any open-material industrial machine with a hardened nozzle and 390°C+ hot end — same PEKK chemistry class, fraction of system cost, no platform lock-in. Open-material access also simplifies multi-supplier qualification.
What is the difference between PEKK and PEEK chemistry?
Both are PAEK (PolyArylEtherKetone) family polymers. PEEK (PolyEtherEtherKetone) has one ether and one ketone group per repeat unit; PEKK (PolyEtherKetoneKetone) has two ketone groups. The 60/40 PEKK-A copolymer ratio yields a higher Tg (165°C vs. 143°C), a lower melt temperature (305°C vs. 343°C for PEEK), and inherent UL 94 V-0 behavior. In practice: PEKK-A is easier to print, has a higher Tg, and costs less — PEEK is the established standard with broader existing material qualifications.
