Typical applicationsStiff parts that must stay dimensionally stable in changing humidity — Polymaker sells this grade specifically on low moisture sensitivity[17][1]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 (Extrudr DURAPRO PA12 CF)[18]190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][4]
Bed temperature°C110 (Extrudr DURAPRO PA12 CF)[18]35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6]
Enclosure / chamber requirement1–5Enclosure required (passive)[19][1]Open frame is fine[5]
Part cooling fanNot documentedFan on[5]
Bed surface & adhesion aidPEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[20][19]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s12 at Extrudr's 150 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[18][21]Not documented
Warping tendency1–5Not documentedNone[5]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[20]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed[19]Not documented
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning[19]Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[22][5]
Extruder requirementNot documentedNozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[22]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA12-CF10 and recommends hardened steel or ruby[1]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[22][23]
Abrasiveness1–5Highly abrasive — standard CF composite; Polymaker puts brass nozzle life at roughly 9 h on PA12-CF10[1]Moderately abrasive — wood fill[22]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles[24]Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[22]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed[20]Not documented
Hotend requirementMay require an all-metal hot end (Simplify3D)[20]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High (0.8–2 %) — 1.5 % equilibrium, the lowest of Polymaker's nylon composites and less than half its PA6-GF25[1][25]High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5]
Equilibrium moisture content at ~50 % RH%1.5 equilibrium water absorption (Polymaker Fiberon PA12-CF10)[1]1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5]
Drying temperature & time80–100 °C; storage below 20 % RH[24][1]55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][22]
Symptoms when wetNot documentedBambu Lab flags pre-drying and ventilation as specific requirements for this grade[22]
Effect of moisture on strengthPolymaker's own dry/wet blocks for PA12-CF10 change little: at 2.92 % moisture tensile falls 77.4 → 71.7 MPa and modulus 3311 → 3132 MPa, against a halving for its PA6 grades[1][17]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[24][5]
Storage requirementSealed below 20 % RH with desiccant[24]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[26][27]Not documented
Mechanical Properties
Tensile strength (XY)MPa77.4 ± 1.1 printed XY dry (Polymaker Fiberon), 71.7 ± 0.7 conditioned to 2.92 % moisture, ISO 527; 3DXTech quotes 72 at break. Stratasys FDM Nylon 12CF spans 76.5-124 at break printed XZ across five machine and tip combinations (ASTM D638)[1][2][28]26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][4][6]
Young's modulusMPa3311 ± 135 printed XY dry and 3132 ± 124 conditioned, ISO 527 (Polymaker Fiberon); 3DXTech quotes 8000. Stratasys FDM Nylon 12CF spans 7910-15400 printed XZ against 2130-3000 in ZX (ASTM D638)[1][2][28]2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][4][6]
Elongation at break%4.2 ± 0.4 printed XY dry and 5.3 ± 0.3 conditioned, ISO 527 (Polymaker Fiberon); 3DXTech quotes 2.1 at break[1][2]4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][4][6]
Flexural strengthMPa90 (printed XY, 3DXTech, ISO 178). Stratasys FDM Nylon 12CF spans 152-200 printed XZ against 61-73 in ZX (ASTM D790)[2][28]55 ± 4 printed XY, ISO 178 (Bambu Lab)[5]
Flexural modulusMPa7900 (printed XY, 3DXTech, ISO 178)[2]2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5]
Charpy impact, notchedkJ/m²9.9 ± 0.7 printed XY dry and 10.2 ± 0.8 conditioned, ISO 179 notched (Polymaker Fiberon)[1]3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][4]
Other impact dataIzod notched 102-138 J/m printed XZ against 22.4-45.5 J/m in ZX (Stratasys FDM Nylon 12CF, ASTM D256)[28]Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][4]
Layer adhesion / Z tensileMPa52.2 ± 0.8 printed Z dry (Polymaker Fiberon) — 67 % of XY, unusually isotropic for a filled nylon; 42.1 ± 1.8 conditioned. Stratasys FDM Nylon 12CF gives 32.7-38.4 at break printed ZX (ASTM D638)[1][28]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 PA12 filament[29]Not documented
Creep resistance / sustained load1–5Good. Ensinger rates its PA66-CF30 compound for sustained static and dynamic load at 110 °C continuous service; the PA12 matrix takes up 1.5 % equilibrium moisture against PA6's several per cent, so a PA12-CF part drifts less in service[30][1]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[31][32][33]
Fatigue / repeated-flex resistance1–5Good. Stratasys sells unfilled FDM Nylon 12 specifically for repetitive-flex parts on the strength of its fatigue properties, and Ensinger reports improved fatigue strength for carbon-filled nylon compounds[30]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[34][5]
Elasticity / flexibility1–5Rigid[1]Rigid[5]
Z strength as % of XY%31-50 (Stratasys FDM Nylon 12CF, ZX against XZ tensile at break, ASTM D638, five machine and tip combinations) against 67 (Polymaker Fiberon PA12-CF10, printed Z against XY)[1][28]58 by tensile, 51 by flexural (printed, Bambu Lab)[5]
Thermal Properties
HDT at 0.45 MPa°C131 (ISO 75, 0.45 MPa, Polymaker Fiberon). Stratasys FDM Nylon 12CF gives 160 printed XY and 168 ZX, and 175 with unidirectional toolpaths (ASTM D648 at 66 psi)[1][28]60 (ISO 75, 0.45 MPa)[5]
HDT at 1.8 MPa°C105 (ISO 75, 1.8 MPa, Polymaker Fiberon). Stratasys FDM Nylon 12CF gives 130 printed XY and 154 ZX (ASTM D648 at 264 psi)[1][28]57 (ISO 75, 1.8 MPa)[5]
Glass transition (Tg)°C55 (DSC, Polymaker Fiberon)[1]54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[5][6]
Melting point / Vicat°C171 melting (DSC); Vicat 170.2 (ISO 306)[1]156 peak melt (DSC)[5]
Thermal expansion (CTE)µm/m·KStratasys FDM Nylon 12CF gives 116 on XY-built and 37 on ZX-built specimens over -50 to 20 °C, rising to 181 (XY) and 46 (ZX) above the 37.5 °C glass transition (ASTM E831); Extrudr quotes 100 for DURAPRO PA12 CF (ISO 11359-2)[18][28]Not documented
Flammability / UL 94Flammable; no UL 94 rating published for the grades surveyed[26]Not documented
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement — unstabilised polyamide yellows under UV[19]Degrades within weeks outdoors[35]
Chemical resistanceWithstands oils, fuels and alkalis[19]Not documented
Water / humidity resistance in service1–5Good — minor absorption; the most humidity-stable nylon composite here[17][1]Not documented
Food contactNot food-contact certified as filament[19]Not documented
Biodegradability / compostabilityNot biodegradable[19]Not documented
RecyclabilityNot accepted in household plastic collection[19]Not documented
Electrical & ESD propertiesSurface resistivity above 10¹² ohm — insulating (Polymaker Fiberon, ANSI/ESD S11.11)[1]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[36]Low hazard — minimal VOC and particle emission[36]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[36]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[36]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[36]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[36]None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[22]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[26]Not documented
Post-Processing
Sanding & machiningSands poorly — gums rather than powders[20]Sands and stains like timber — the usual reason for choosing it[4]
Gluing & solvent weldingCyanoacrylate; no common solvent welds polyamide[20]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[20]Not documented
Support material pairingNot documentedSupport for PLA (Bambu Lab)[5]
Dimensional accuracy & detailPolymaker's own conditioning test found PA12-CF10 was the only nylon that did not grow past its original size after moisture conditioning[17]Wood 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.[37]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[38]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[37]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[38][39]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[37]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[40][39]
