Printing Parameters
Nozzle temperature°C260–290 (Bambu Lab); 280–300 (Polymaker Fiberon)[2][1]190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[6][4]
Bed temperature°C40–50 (Polymaker Fiberon)[1]35–45 (Bambu Lab); 50–70 (Fiberlogy)[6][7]
Enclosure / chamber requirement1–5Enclosure required (passive) — Bambu Lab specifies a 45–60 °C chamber, Polymaker room temperature[2][1]Open frame is fine[6]
Recommended chamber temperature°C45–60 (Bambu Lab); room temperature (Polymaker Fiberon)[2][1]Not documented
Part cooling fanNot documentedFan on[6]
Bed surface & adhesion aidEngineering or high-temperature plate with glue (Bambu Lab)[2]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; Polymaker rates its grade to 300 mm/s[2][1][18]Not documented
Warping tendency1–5Not documentedNone[6]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[2]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed[19]Not documented
Overall printing difficulty1–5Expert / industrial hardware only — enclosure, hardened nozzle, an 80 °C dry and a printer that can hold the filament dry throughout[2][1][20]Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[21][6]
Extruder requirement0.6 mm nozzle recommended by Bambu Lab; 0.4 and 0.8 also supported[2]Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[21]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA6-CF20 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[21][22]
Abrasiveness1–5Highly abrasive — standard CF composite; Polymaker puts brass nozzle life at roughly 9 h[1]Moderately abrasive — wood fill[21]
Nozzle clog risk1–5Very high — frequent jams without careful setup; the combination of moisture and fibre is the worst case in the dataset[20][1]Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[21]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed[23]Not documented
Hotend requirementHardened steel or ruby nozzle plus an all-metal hot end rated to 300 °C[1][2]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Very high (>2 %) — 2.35 % saturated at 25 °C / 55 % RH (Bambu Lab)[2]High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[6]
Equilibrium moisture content at ~50 % RH%2.35 saturated at 25 °C / 55 % RH (Bambu Lab)[2]1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[6]
Drying temperature & time80 °C for 8–12 h (Bambu Lab); 100 °C for 10 h (Polymaker Fiberon)[2][1]55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[6][21]
Symptoms when wetPopping and cracking during extrusion, then hard-to-diagnose defects[24]Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[21]
Effect of moisture on strengthPolymaker publishes dry and wet printed blocks for PA6-CF20 itself: at 5.30 % moisture tensile falls 109.3 → 54.7 MPa and modulus 8636 → 2508 MPa, while notched Charpy rises 11.0 → 35.6 kJ/m². Fibre reinforcement reduces but does not remove the effect[1][24]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[20][6]
Storage requirementSealed below 20 % RH with desiccant; often needs to stay in a dryer while printing[20]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[1][25]Not documented

Brittleness1–5Moderate[2][1]Brittle — snaps with little warning[6]
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 nylon filament[26]Not documented
Creep resistance / sustained load1–5Good. Ensinger rates its PA66-CF30 injection-moulding compound for exceptional performance under both static and dynamic loading with 110 °C continuous service; in a printed part the fibre restrains the matrix, but conditioning to equilibrium moisture still softens it[27][24]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[28][29][30]
Fatigue / repeated-flex resistance1–5Good. Ensinger states its PA66-CF30 compound has improved fatigue strength in tension, flexure and compression against unfilled and glass-filled PA66[27]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[31][6]
Elasticity / flexibility1–5Rigid[2]Rigid[6]

RecyclabilityFibre-filled polyamide is not accepted in household plastic collection[19]Not documented
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (3DXTech, ASTM D257)[5]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[34]Low hazard — minimal VOC and particle emission[34]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[34]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[34]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[34]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[34]None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[21]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[1]Not documented
Post-Processing
Sanding & machiningSands to a matte finish; the fibre makes it cut more cleanly than unfilled nylon[23]Sands and stains like timber — the usual reason for choosing it[4]
Gluing & solvent weldingCyanoacrylate; no common solvent welds polyamide[23]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[23]Not documented
Support material pairingPolyDissolve S1 (Polymaker Fiberon)[1]Support for PLA (Bambu Lab)[6]
Dimensional accuracy & detailConditioned parts grow; Polymaker declines to publish a standard dimensional allowance because it depends on geometry and infill[24]Wood grain hides layer lines; colour darkens with nozzle temperature[6][4]
Solvents & Solubility
Soluble inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[35]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[36]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[35]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[36][37]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[35]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[38][37]
