PA6-CF carbon fibre nylon 3D printing service · UK · quoted in 6 hours.
Our stiffest, strongest material · and it prints without a heated chamber, unusual for a CF nylon.
Four quick visuals. Start with which material to pick and where PA6-CF works; the engineering detail is at the end if you want it.
Climate-controlled indoor CF nylon · fuel-system parts · drone airframes · classic-car bracketry · humid service where PA6-CF gives up
Peak dry stiffness = PA6-CF · driest moisture story = PA12-CF · sustained outdoor UV with optics = ASA / UV-stable PC · UL94 V-0 = PA6-FR / PPS
PA6 is the high-crystallinity workhorse nylon · highest stiffness and strength of the nylon family, but the most moisture-sensitive. 20% chopped CF aligns with extrusion · drives XY strength + 2.14× anisotropy.
Plan orientation in CAD before slicing · annealing 100°C/16h locks in crystallinity. Wet state anisotropy rises to 2.33× as Z weakens faster than XY.
"James handled the 3D printing for a functional heat resistant component we needed in batch production. He helped dial in the prototype first with their design service, then produced the final batch with really consistent results. Super fast 3D print turnaround and great quality across all the 3D printed parts. Will 100% be coming back."
"We needed a sit-in F1-car for an exhibition to showcase our new racing game. 3D Printing Express took our CAD, optimised it for strength and weight as we had no idea how it all worked! Turned out beautifully. They colour matched the finish and was looking like the real deal. On show day the cockpit ran non-stop, adults and kids jumped in. Multiple visitors asked who built it."
"We ordered a batch of 100 PA-12 parts from 3D Printing Express and could not be happier. Every part arrived consistent, dimensionally accurate, and ready for use straight from the box. The PA-12 gave us the strength and stability we needed for functional testing, with minimal post-processing required. Delivery was on time, communication was excellent, and their QC clearly made a difference."
The strongest CF nylon we print. Drops ~53% to 54.7 MPa when moisture-saturated · PA6 is the most hygroscopic nylon we stock. Dry-service only.
The stiffest material 3DPE prints · ~2.5× plain PLA and well above PET-CF (5481) and PPS-CF (5447). Falls ~71% to 2508 MPa wet · keep it dry.
Holds shape to 215°C @ 0.45 MPa, 173°C @ 1.8 MPa structural load (after the mandatory anneal). Genuine engineering heat tolerance.
~60% lighter than aluminium for the same load path. Heavier than PA12-CF (1.06) but far stronger and stiffer.
The use cases where PA6-CF earns its place · high-strength outdoor CF nylon, fuel-resistant chemistry, room-temperature chamber, and a printable lead time when CNC or moulding can't justify the cost.
Engineering materials are bought on what they can do · sold on what they can't. Pick a different filament if any of these apply to your part.
The moisture story is the lead. PA6-CF loses ~53% tensile and ~71% stiffness when wet · it is a dry-service material. For a drone that lives on an airfield year-round, PA12-CF (moisture-immune) or PA612-CF is the right call, not PA6-CF.
PA6 is the workhorse engineering nylon used in injection-moulded automotive interior, industrial machinery, and load-bearing parts. Engine-bay temperatures, hydrocarbon exposure, vibration · all within the chemistry's design envelope.
For 1970-2000 cars where the original injection-moulded part is no longer available. Fuel/oil resistance + UV tolerance + dimensional stability over decades makes PA6-CF the no-compromise replacement.
Workshop environments that are humid or oily · vinyl-coating lines, paint shops, washdown areas. Where PA6-CF would lose stiffness wet and PA12-CF would bend under heat, PA6-CF holds both.
A side-by-side of the three carbon-fibre engineering nylons most engineers compare. PA6-CF wins on peak dry strength + stiffness + heat; PA12-CF wins on moisture-immune dimensional stability; PA612-CF balances strength with far lower wet loss.

PA6-CF is 20% carbon-fibre-reinforced polyamide 6 · a semi-crystalline aliphatic nylon reinforced with chopped carbon fibre. PA6 is the workhorse engineering nylon · high crystallinity gives it the highest stiffness and strength of the nylon family. Carbon-fibre at 20 wt% delivers 115.3 MPa tensile XY dry, an 8636 MPa Young's modulus (the highest of any material 3DPE prints), 215°C HDT at 0.45 MPa, density 1.17 g/cm³. The trade-off is moisture: PA6 is the most hygroscopic nylon we stock · a fully-saturated specimen loses ~53% tensile (115.3 → 54.7 MPa) and ~71% stiffness (8636 → 2508 MPa), while notched impact actually rises (11.0 → 35.6 kJ/m²) as the plasticised matrix toughens. The defining design consideration is therefore drying discipline · print and store bone-dry. It is the dry-service strength/stiffness/heat champion, NOT an outdoor or humid-service material.
"PA6-CF is the CF nylon I reach for when the part has to be as strong and stiff as we can print and it lives somewhere dry. Nothing else we stock touches its 8636 MPa modulus. The catch is moisture · it loses about half its tensile and most of its stiffness if it picks up water, so it goes in the dryer before printing and the finished part is for climate-controlled service. The trade is anisotropy · 2.1× XY-to-Z means you really do need to think about orientation before you slice. For anything humid or outdoor I send people to PA612-CF or PA12-CF instead."
Three questions every engineer Googles when picking PA6-CF · the polyamide chemistry, how 20% carbon fibre changes it, and what the UV claim actually means in service.
PA6 (nylon 6) has the shortest repeat unit of the common nylons · 6 carbons between amide groups means the highest density of hydrogen-bonding amide sites, giving the highest crystallinity, stiffness and strength of the family · and the highest moisture uptake. Tm 218.5°C, HDT 215°C @ 0.45 MPa, equilibrium water ~3.3%.
20% chopped carbon fibre (~100-200 micron length) aligns along extrusion direction during deposition · drives the 2.14× XY/Z anisotropy ratio. Higher than PA12-CF (1.48×) because the 20% CF loading is denser than PA12-CF's 10%. Design load paths along XY whenever possible.
PA6-CF loses ~53% of its tensile XY wet (115.3 → 54.7 MPa per ISO 527, 2.57% moisture) and ~71% of its stiffness (8636 → 2508 MPa) · the most moisture-sensitive nylon we stock. Notched impact moves the other way, rising 11.0 → 35.6 kJ/m² as the plasticised matrix toughens. The design takeaway: print and store bone-dry; for humid/outdoor service use PA612-CF or PA12-CF.
Polyamide 6 (PA6, nylon 6) is a semi-crystalline aliphatic polyamide · a single 6-carbon repeat unit (from caprolactam) gives it the shortest amide spacing of the common nylons. That high density of hydrogen-bonding amide groups is why PA6 has the highest crystallinity, stiffness and strength of the nylon family · and also why it is the most hygroscopic: those same amide sites attract water, which plasticises the matrix and drives the large wet-property drop. The 20% chopped carbon fibre carries the dry stiffness to 8636 MPa, the highest of any material 3DPE prints.
The commercial pedigree is fuel-line tubing. PA612 is the engineering polymer used as the inner layer of multi-layer automotive fuel-line systems specifically because of its resistance to extraction by petrol, diesel, E85 ethanol-blends, and engine oils over decades of service. The same hydrocarbon-resistance carries through to the FDM-printed grade · engine-bay fixturing, fuel-system brackets, and oil-environment service parts inherit the chemistry's pedigree.
Every amide linkage in a nylon chain is a potential hydrogen-bonding site for water molecules. More amides per unit length means more water-attackable sites. PA6 has one amide every 6 carbons (the most). PA12 has one every 12 (the fewest). PA612 averages roughly one amide every 9 carbons · materially fewer than PA6 but more than PA12. The practical result: 3.3% equilibrium water absorption (TDS value) vs 3.33% for PA6 and 1.5% for PA12.
The wet-state penalty is the price of PA6's high crystallinity. PA6-CF loses ~53% of dry tensile and ~71% of stiffness when fully saturated (115.3 → 54.7 MPa, 8636 → 2508 MPa). PA612-CF loses far less (~22% stiffness); PA12-CF is essentially moisture-immune but starts from a lower stiffness baseline (3311 MPa). No CF nylon gives you both peak dry strength AND wet stability · PA6-CF is the peak-dry-strength end of that trade.
Our stocked grade is 20% carbon fibre by weight, chopped to short segments (typically 100-200 microns long, not continuous strands). The fibres orient along the print-head direction as the molten filament extrudes. That orientation drives the 2.14× XY/Z anisotropy ratio · XY (in the print plane) inherits the fibre-alignment strength; Z (layer-to-layer) relies on polymer-to-polymer bonding with minimal fibre bridging across layers.
On the UV claim · the manufacturer's product page publishes a 92% tensile strength retention figure after 1,000 hours of UV exposure. This is a real published number on the supplier-side, and the PA6 nylon backbone chemistry in PA612 does support better UV behaviour than PA6. However, the TDS V1.0 does not specify the test method (ISO 4892, ASTM G154, QUV cycle, or otherwise) or the specific exposure conditions. We present this on the page as the manufacturer's published claim rather than as an ISO-tested specification. For mission-critical outdoor specifications, request a 3DPE-printed coupon for third-party accelerated-weathering testing.

According to the Fiberon PA6-CF20 TDS, PA6-CF20 reaches Young's modulus 8636 MPa (XY) dry per ISO 527 · the stiffest grade in the Polymaker/Fiberon range · but drops 71% to 2508 MPa when moisture-conditioned (eq. water ~3.3%), with HDT 215 °C @ 0.45 MPa and Tm 218.5 °C.
Two reasons. First, the PA6 base polymer is the workhorse engineering nylon · widely used in injection-moulded automotive, industrial, and consumer parts. Higher mechanical performance than PA12 or PA612, with the trade-off of higher moisture sensitivity (better than PA6 or PA66). Second, the manufacturer publishes a wet/dry mechanical pair published · the most honest moisture-sensitivity disclosure of any PA-CF grade on the carbon-fibre grade · though we note the test method and standard are not specified in the TDS V1.0, so we present this as the manufacturer's published claim rather than as an ISO-tested specification. For service applications that need real outdoor tolerance over months and years, PA6-CF is the only commodity CF nylon with a published UV claim · everything else (PA12-CF, PA6-CF) yellows and embrittles in sustained UK sun.
Yes · density 1.17 g/cm³ vs PA12-CF at 1.06 g/cm³. The TDS V1.0 publishes 1.17 g/cm³ for this specific grade · and the chemistry supports it (20% CF loading at 1.8 g/cm³ raises composite density less than 25% glass-fibre at 2.5 g/cm³ in PA6-GF which is why PA6-GF density is 1.20). Lowest-density CF engineering nylon on our shelf.
PA6-CF wins on strength (115 vs 77 MPa XY tensile dry), stiffness (8636 vs 3311 MPa Young's modulus), and HDT (215 vs 131°C at 0.45 MPa). PA12-CF wins decisively on moisture stability (moisture-immune vs PA6 losing ~53% tensile wet), anisotropy (1.48× vs 2.14×), and ductility. For dry high-load service, PA6-CF. For humid/outdoor or dimensional stability, PA12-CF.
PA6-CF is the strongest, stiffest CF nylon we print (115.3 MPa tensile XY, 8636 MPa modulus, 215°C HDT) but the most moisture-sensitive · it loses ~53% tensile and ~71% stiffness when saturated, while notched impact rises (11.0 → 35.6). For humid or outdoor service use PA612-CF (far lower wet loss) or PA12-CF (moisture-immune). PA6-CF is a dry-service strength/stiffness hero.
No · the TDS specifies room temperature chamber. PA6-CF prints reliably on a build plate at 40-50°C without enclosure heating · same as PA6-GF. This is the practical advantage vs PA12-CF (typically prefers some chamber heating to suppress warp on large parts) or PC (needs 70-100°C chamber). PA6-CF runs on standard open-frame industrial FDM.
The TDS V1.0 lists Tg as N/A · not separately published for this specific grade. Literature values for PA6 base polymer range from 46°C (polymerprocessing.com) to ~70°C in CF-filled variants. For practical design margin, assume Tg 74.2°C · loaded parts above this temperature transition from glassy to leathery. HDT at 0.45 MPa is 215°C (3-minute load test) and HDT at 1.8 MPa is 114°C. Sustained load above 90-100°C is a red-line.
Hardened steel or ruby. Carbon-fibre is abrasive · brass nozzle lifetime is ~9 hours per the TDS, same as PA12-CF and PA6-CF. We run hardened steel on every CF print as standard, included in the quote · no surcharge.
Excellent for hydrocarbons · the long-chain PA6 polymer is used commercially as the inner layer of multi-layer fuel-line tubing in modern automotive systems specifically because of its low extractables under petrol, diesel, ethanol-blend fuels, and engine oils. Native pass for fuel chemistry. Limited against acetone, MEK, and strong alkalis. Fails against strong acids, formic acid, chlorinated solvents, and sustained hot water above 80°C.

|---|---|---|
| Petrol / gasoline | Excellent | PA612 commercial fuel-line inner-layer chemistry |
| Diesel | Excellent | Including biodiesel and E85 ethanol-blends |
| Engine oil, gear oil, hydraulic oil | Excellent | All standard service grades |

| Coolant / antifreeze (ethylene glycol) | Excellent | Including diluted service coolant |
| Methanol, ethanol, IPA | Excellent | Cleaning + assembly OK |
| Detergents, soap, weak alkalis | Excellent | Workshop wash-down OK · better than PA6 chemistry |
| Sea water / saline solution | Good | Better than PA6 thanks to long-chain backbone · short-to-medium term immersion |
| Hydrogen peroxide ≤ 6% | Good | Stronger H₂O₂ attacks long-term |
| Acetone | Limited | Surface attack + softening over hours |
| MEK, toluene, xylene | Limited | Brief contact only · no soak |
| Strong alkalis (NaOH > 10%) | Limited | Polymer-chain hydrolysis risk |
| Weak organic acids (acetic, citric) | Limited | Slow attack over weeks |
| Hot water (sustained > 80°C) | Limited | Hydrolysis risk · better than PA6 but worse than PA12 |
| Strong acids (sulphuric, HCl, nitric) | Fails | Polymer chain breakdown |
| Chlorinated solvents long-term (TCE, DCM) | Fails | Solvent crazing + dissolution |
| Phenols | Fails | Strong PA solvent |
| Formic acid | Fails | Industry-standard PA dissolution solvent |
Ratings reflect long-term immersion / sustained exposure. Brief contact (cleaning wipes, splashes) is more forgiving. For mission-critical chemical service, request a 7-day immersion sample before committing the design.
Yes · the TDS strongly recommends 100°C for 16 hours post-print. Annealing relaxes residual print stresses, raises crystallinity, and gains 10-20% tensile and HDT. Causes ~0.1% XY and ~0.2% Z shrinkage (per the manufacturer shrinkage block · 40mm specimen). For load-bearing engineering parts, annealing is the recommended default.
Standard PA6-CF20 is rated UL94 HB at 1.5mm wall · the lowest horizontal-burn rating, but rated. For UL94 V-0 / V-2 self-certification we stock dedicated flame-retardant grades on request, including PA6-FR (real injection-moulding category, not currently in our filament range).
No · standard PA6-CF20 is insulative. Surface resistivity is >10¹² Ω/sq per the TDS (rated OL · overload, beyond ESD-safe range). The 20% CF loading sits at the edge of the percolation threshold but is not consistently conductive. For ESD-sensitive applications use PA612-ESD (dedicated anti-static grade in the same base polymer family) or PETG-ESD.
Continuous service (dry): -40 to ~90°C (Tg ~74°C-limited). Short-term load: up to ~215°C (HDT at 0.45 MPa). Outdoor / humid: NO · loses ~53% tensile + ~71% stiffness saturated · use PA612-CF or PA12-CF instead. Print and store bone-dry. Not for steam autoclave (Tg too low), not for ESD service (insulative), not for live hinges (CF brittleness).
