WHY CARBONX Nylon 6+CF
3,800 MPa Modulus. 147°C HDT. Gen3 Formulation.
CarbonX™ Nylon 6+CF (PA6+CF Gen3) is 3DXTech’s carbon fiber reinforced Polyamide 6 — delivering 3,800 MPa tensile modulus, 147°C heat deflection temperature, and broad chemical resistance to fuels, oils, and hydraulic fluids. The third-generation formulation improves interlayer adhesion and print reliability over earlier PA6+CF variants. For structural applications where PA6’s higher crystallinity, lower cost, and chemical profile outperform PA12.
Gen3 Formulation — Improved Interlayer Adhesion
Third-generation PA6+CF compound with enhanced bonding chemistry. Improved Z-strength and layer-to-layer cohesion over first- and second-generation PA6+CF materials reduces delamination risk in structural parts.
147°C HDT — Semi-Crystalline Advantage
PA6 Tg is just 70°C, yet HDT reaches 147°C at 0.45 MPa — a direct result of PA6’s high crystallinity. Parts maintain structural integrity far above the glass transition, enabling continuous-use temperatures unfilled PA6 cannot match.
Chemical Resistance: Oils, Fuels, Hydraulic Fluid
PA6 exhibits stronger resistance to mineral oils, fuels, and hydraulic fluids than PA12. A more chemically aggressive nylon for fluid-contact structural components in automotive, industrial, and off-highway applications.
Lower Cost than PA12+CF
PA6 raw material costs less than PA12. CarbonX Nylon 6+CF starts at $78/500g — lower cost of entry versus the PA12-based CF variant for applications where PA6 chemistry meets requirements.
PRINTING WITH CARBONX Nylon 6+CF
PA6+CF Gen3 — Moisture Management Is Critical
CarbonX Nylon 6+CF requires a hardened steel nozzle — standard brass will wear rapidly against the carbon fiber. PA6 absorbs moisture significantly faster than PA12 — strict drying protocol before every print session is non-negotiable. Industrial hardware with a heated enclosure delivers the most reliable results.
- Extruder Temp 260–285°C — all-metal hot end required
- Bed Temp 70–90°C — PEI or garolite build surface
- Chamber Temp Recommended — heated enclosure reduces Nylon 6 warping tendency
- Nozzle Hardened steel ≥0.4mm — MANDATORY. Standard brass nozzle will wear rapidly against CF.
- ⚠ Drying Warning PA6 absorbs moisture faster than PA12. Dry at 80°C for 4 hours minimum before every print session — no exceptions. Print directly from dryer for best results. Wet PA6 filament prints with bubbling, stringing, and severely degraded layer adhesion.
- ⚠ 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
147°C HDT — Semi-Crystalline PA6 Outperforms Its Tg
PA6 has a relatively low glass transition (70°C), yet its high-crystallinity structure delivers a 147°C heat deflection temperature. This semi-crystalline advantage means parts maintain structural integrity far above Tg — a key reason PA6 outperforms amorphous materials in long-term structural applications.
HDT at 0.45 MPa. Significantly higher than Tg due to PA6’s semi-crystalline morphology — the crystalline phase retains stiffness well above the glass transition temperature. CF reinforcement further elevates HDT over unfilled PA6.
PA6 Tg is relatively low compared to PA12 (158°C). This is not a service-temperature limit — the crystalline phase dominates structural performance. HDT of 147°C demonstrates stiffness retention well above Tg in crystalline domains.
Estimated continuous-use temperature for PA6+CF under load. CF reinforcement improves stiffness retention; semi-crystalline PA6 maintains structural performance at temperatures that would deform amorphous materials with similar Tg values.
Required before every session. PA6 absorbs moisture faster than PA12 — re-dry even a spool opened hours earlier. Print directly from a heated dry-box for best interlayer adhesion. Wet PA6 prints with bubbling and layer delamination.
CHEMICAL RESISTANCE
Stronger Chemical Resistance Than PA12 for Oils, Fuels & Hydraulic Fluid
CarbonX™ Nylon 6+CF’s PA6 matrix delivers broader resistance to mineral oils, fuels, and hydraulic fluids than PA12-based CF variants. For fluid-contact structural components in automotive, industrial, and off-highway applications, PA6 chemistry provides a meaningful advantage over PA12.

MATERIAL CARE
PA6 Absorbs Moisture Fast — Strict Drying Protocol Is Non-Negotiable
PA6 absorbs moisture significantly faster than PA12 — even brief ambient exposure between print sessions can degrade layer adhesion. Follow this protocol every session. Print directly from dryer for best results.
Dry Before Every Session
80°C minimum / 4 hours minimum. PA6 absorbs moisture faster than PA12 — even a spool that was sealed yesterday benefits from a fresh drying cycle before printing.
Print From the Dryer
For best interlayer adhesion, print directly from a heated dry-box or dryer system. PA6 moisture re-absorption during long print runs causes degraded layer bonding and surface quality.
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 with fresh desiccant is recommended.
Recognize Wet Filament Symptoms
Popping or crackling during extrusion, rough surface texture, layer delamination, and visible bubbling in the melt are signs of moisture contamination. Re-dry at 80°C / 4 hr and restart.
HOW IT COMPARES
CarbonX™ Nylon 6+CF vs. Commonly Evaluated Alternatives

FREQUENTLY ASKED
CarbonX™ Nylon 6+CF — Buyer Questions Answered
What is CarbonX™ Nylon 6+CF?
CarbonX™ Nylon 6+CF is 3DXTech’s Gen3 carbon fiber reinforced Polyamide 6 (PA6) filament. It delivers 3,800 MPa tensile modulus and 147°C heat deflection temperature. Available in Black only. A hardened steel nozzle is mandatory — CF reinforcement is abrasive and will rapidly wear brass nozzles. PA6 absorbs moisture quickly — strict drying at 80°C / 4 hr is required before every print session.
What temperatures does CarbonX™ Nylon 6+CF require?
CarbonX™ Nylon 6+CF requires an extruder temperature of 260–285°C and a bed temperature of 70–90°C. A heated enclosure is recommended to control warping. Dry at 80°C for 4 hours minimum before every print session — PA6 is significantly more hygroscopic than PA12. All-metal hot end rated to 300°C+ is required.
Why is PA6 Tg only 70°C but HDT is 147°C?
PA6 is semi-crystalline. The glass transition at 70°C represents the amorphous domains softening — but the crystalline phase retains stiffness well above Tg. This is why PA6 heat deflection temperature (147°C at 0.45 MPa) is dramatically higher than its Tg. For structural applications, HDT is the relevant thermal performance metric — not Tg.
How does Nylon 6+CF compare to Nylon 12+CF?
Key differences: PA6+CF has better chemical resistance to mineral oils, fuels, and hydraulic fluids. PA6+CF is lower cost ($78 vs. $88/500g). PA12+CF has near-zero moisture absorption (PA6 is significantly more hygroscopic) — making PA12 easier to dry and maintain. PA12+CF also has 8,000 MPa tensile modulus vs. 3,800 MPa for PA6+CF. Choose PA6 for chemical resistance and cost; choose PA12 for higher modulus and simpler moisture management.
Why does CarbonX™ Nylon 6+CF 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.
What applications use CarbonX™ Nylon 6+CF?
CarbonX™ Nylon 6+CF is used in automotive under-hood structural components, industrial fluid system brackets, production tooling and fixtures requiring stiffness at elevated temperatures, aerospace ground support hardware, and off-highway equipment structural parts. Any application where PA6 chemistry (chemical resistance to oils/fuels, lower cost) outweighs the moisture management trade-off versus PA12.
What is the Gen3 formulation improvement?
3DXTech’s Gen3 designation indicates the third-generation PA6+CF compound, featuring improved interlayer adhesion chemistry and enhanced print reliability vs. earlier PA6+CF materials. Gen3 reduces delamination tendency in structural parts and extends the printable process window. Full processing parameters are documented in the CarbonX PA6+CF Gen3 TDS.
Should I choose Nylon 6+CF or PC+CF?
CarbonX™ PC+CF has a higher Tg (~147°C vs. 70°C for PA6) and lower moisture absorption. Choose Nylon 6+CF when chemical resistance to fuels, oils, and hydraulic fluids is the primary requirement, or when lower material cost is a priority. Choose PC+CF when a higher glass transition temperature and inherently lower moisture uptake are required for the application.
