Identity & Market
Base polymer / chemistryHigh-temperature carbon-fibre nylon. Bambu Lab's PAHT-CF and Polymaker's PA612-CF15 both use a long-chain polyamide matrix for lower moisture uptake than PA6[1][2]PLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[3][4]
Densityg/cm³1.03 (Polymaker PA612-CF15) and 1.06 (Bambu Lab), ISO 1183[1][2]1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[5][4][6]
Typical priceUSD/kg1 kg-equivalent spools cluster near 60[1][7]1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[8][9][10]
Price range across brandsUSD/kg50–70 across brands; Bambu Lab 50, Polymaker Fiberon PA612-CF15 70[1][7]14–76 across brands; SUNLU 14, ELEGOO 19, Bambu Lab 25, Prusament 44, Filament PM 49 on 0.5 kg spools, colorFabb 76[9][8][11][12][13][10]

Typical applicationsUnder-bonnet and near-motor parts needing 170 °C-plus heat deflection with less humidity drift than PA6[1][2]Decorative and model-making prints that are sanded and stained like timber[5][4]
Diameter tolerance± mmNot documented±0.03 (Bambu Lab)[5]
Printing Parameters
Nozzle temperature°C260–290 (Bambu Lab)[1]190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][4]
Bed temperature°CNot documented35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6]
Enclosure / chamber requirement1–5Enclosure required (passive) — Bambu Lab specifies a 45–60 °C chamber[1]Open frame is fine[5]
Recommended chamber temperature°C45–60 (Bambu Lab)[1]Not documented
Part cooling fanNot documentedFan on[5]
Bed surface & adhesion aidPEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[14][15]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s8 at Bambu Lab's 100 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][16]Not documented
Warping tendency1–5Not documentedNone[5]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[14]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed[15]Not documented
Overall printing difficulty1–5Expert / industrial hardware only[1][17]Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[18][5]
Extruder requirement0.6 mm nozzle recommended by Bambu Lab; 0.4 and 0.8 also supported[1]Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[18]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA612-CF15 and recommends hardened steel or ruby[2]Brass acceptable; hardened steel for volume work — Bambu Lab's PLA compatibility table lists no hardened-nozzle requirement, but its nozzle guide names wood among the abrasive filaments hardened steel exists for[18][19]
Abrasiveness1–5Highly abrasive — standard CF composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-CF15[2]Moderately abrasive — wood fill[18]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles[17]Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[18]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed[14]Not documented
Hotend requirementMay require an all-metal hot end (Simplify3D)[14]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High (0.8–2 %) — 0.88 % saturated at 25 °C / 55 % RH for Bambu Lab PAHT-CF, a third of its PA6-CF; Polymaker's PA612-CF15 reaches 2.2 % equilibrium[1][2][20]High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5]
Equilibrium moisture content at ~50 % RH%0.88 saturated at 25 °C / 55 % RH (Bambu Lab PAHT-CF); 2.2 equilibrium (Polymaker PA612-CF15)[1][2]1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5]
Drying temperature & time80 °C for 8–12 h (Bambu Lab)[1]55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][18]
Symptoms when wetNot documentedBambu Lab flags pre-drying and ventilation as specific requirements for this grade[18]
Effect of moisture on strengthPolymaker publishes dry and wet printed blocks for PA612-CF15 itself: at 2.57 % moisture tensile falls only 91.9 → 83.1 MPa and modulus 5137 → 3991 MPa — the PA612 backbone absorbs far less than PA6[2][21]No dry-versus-conditioned figures are published. At 1.25 % saturated uptake the practical loss shows as poor layer adhesion, rough surface and weak layers[17][5]
Storage requirementSealed below 20 % RH with desiccant[17]Not documented
Hydrolysis at melt temperaturePolymaker specifies an 80–100 °C dry and storage below 20 % RH; no molecular-weight loss figure is published, and the wet data it does publish is conditioning rather than melt hydrolysis[22][23]Not documented
Mechanical Properties
Tensile strength (XY)MPa92 ± 7 (Bambu Lab) and 91.9 ± 2.0 (Polymaker PA612-CF15, dry/annealed) printed XY, ISO 527; the Polymaker grade only falls to 83.1 ± 2.2 conditioned to 2.57 % moisture[1][2]26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][4][6]
Young's modulusMPa3860 ± 230 (Bambu Lab) and 5137 ± 192 (Polymaker PA612-CF15, dry) printed XY, ISO 527; Polymaker 3991 ± 137 conditioned[1][2]2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][4][6]
Elongation at break%2.6 ± 0.2 dry (Polymaker PA612-CF15) to 8.4 ± 1.8 (Bambu Lab) printed XY, ISO 527; Polymaker 4.1 ± 0.3 conditioned[1][2]4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][4][6]
Flexural strengthMPaNot documented55 ± 4 printed XY, ISO 178 (Bambu Lab)[5]
Flexural modulusMPa4230 ± 210 printed XY, ISO 178 (Bambu Lab)[1]2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5]
Charpy impact, notchedkJ/m²8.1 ± 0.8 printed XY dry and 7.7 ± 0.5 conditioned, ISO 179 notched (Polymaker PA612-CF15)[2]3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][4]
Other impact dataCharpy unnotched 57.5 ± 3.4 and notched 22.8 ± 1.8 printed XY (Bambu Lab, ISO 179)[1]Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][4]
Layer adhesion / Z tensileMPa47 ± 5 (Bambu Lab) and 48.3 ± 3.9 (Polymaker PA612-CF15, dry) printed Z, ISO 527; Polymaker 35.6 ± 3.0 conditioned[1][2]15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5]
Brittleness1–5Moderate[1]Brittle — snaps with little warning[5]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell M88 / R117 on extruded PA66-GF30 stock (ASTM D785); no figure is published for a carbon-fibre long-chain nylon filament[24]Not documented
Creep resistance / sustained load1–5Good. Ensinger rates its PA66-CF30 compound for sustained static and dynamic load with 110 °C continuous service; the long-chain PA612 matrix takes up 0.88 % at saturation, a third of the same maker's PA6-CF, so it holds dimension better[25][2]Poor — no wood-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[26][27][28]
Fatigue / repeated-flex resistance1–5Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[25]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the wood filler cuts elongation and the parts snap without warning[29][5]
Elasticity / flexibility1–5Rigid[1]Rigid[5]
Z strength as % of XY%51 (Bambu Lab) to 53 (Polymaker PA612-CF15), printed[1][2]58 by tensile, 51 by flexural (printed, Bambu Lab)[5]

RecyclabilityNot accepted in household plastic collection[15]Not documented
Electrical & ESD propertiesSurface resistivity above 10¹² ohm — insulating (Polymaker PA612-CF15, ANSI/ESD S11.11)[2]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[31]Low hazard — minimal VOC and particle emission[31]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[31]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[31]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[31]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[31]None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[18]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[22]Not documented
Post-Processing
Sanding & machiningSands poorly — gums rather than powders[14]Sands and stains like timber — the usual reason for choosing it[4]
Gluing & solvent weldingCyanoacrylate; no common solvent welds polyamide[14]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[14]Not documented
Support material pairingNot documentedSupport for PLA (Bambu Lab)[5]
Dimensional accuracy & detailNot documentedWood grain hides layer lines; colour darkens with nozzle temperature[5][4]
Solvents & Solubility
Soluble inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[32]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[33]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[32]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[33][34]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[32]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[35][34]
