PA6/66 vs PLA Wood — documented properties and sources
PropertyPA66 (Nylon 66)PAWood-filled PLAPLA
Market snapshot
Listing priceUSD/kg; dated snapshotsNot documented$34.49/kg median; $13.99–$76.40/kg across 6 dated product listings
Identity & Market
Base polymer / chemistryPolyamide 66, condensed from hexamethylenediamine and adipic acid; melts around 40 °C above PA6[1]PLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[2][3]
Densityg/cm³1.14 (extruded unfilled PA66 stock)[4]1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[5][3][6]
Typical priceUSD/kgNot documented1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[7][8][9]
Price range across brandsUSD/kgNot documented14–76 across brands; SUNLU 14, ELEGOO 19, Bambu Lab 25, Prusament 44, Filament PM 49 on 0.5 kg spools, colorFabb 76[8][7][10][11][12][9]
Market availability1–5Special order, 1–2 makers worldwide — no unfilled PA66 filament appeared in any catalogue searched, and the 3DXTech nylon range offers PA6, PA12 and a 6/66 copolymer but no straight PA66[13][14]Stocked by most mainstream brands[7][8][11][6]
Spool sizes & diametersNot documented1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[11][6][7]
Typical applicationsNot documentedDecorative and model-making prints that are sanded and stained like timber[5][3]
Diameter tolerance± mmNot documented±0.03 (Bambu Lab)[5]
Printing Parameters
Nozzle temperature°CNot documented190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][3]
Bed temperature°CNot documented35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6]
Enclosure / chamber requirement1–5Enclosure required (passive)[1]Open frame is fine[5]
Part cooling fanNot documentedFan on[5]
Warping tendency1–5Not documentedNone[5]
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning[1]Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[15][5]
Extruder requirementNot documentedNozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[15]
Hardware Wear & Reliability
Nozzle hardness required1–4Not documentedBrass 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[15][16]
Abrasiveness1–5Not documentedModerately abrasive — wood fill[15]
Nozzle clog risk1–5Very high — frequent jams without careful setup[17][18]Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[15]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Very high (>2 %)[18]High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5]
Equilibrium moisture content at ~50 % RH%8.5 at saturation on extruded PA66 stock (ASTM D570) — the highest uptake of any polymer in this dataset[4]1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5]
Drying temperature & timeNot documented55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][15]
Symptoms when wetNot documentedBambu Lab flags pre-drying and ventilation as specific requirements for this grade[15]
Effect of moisture on strengthMeasured dry against wet on printed specimens at 6.16 % moisture (Polymaker CoPA): tensile 78.0 → 34.3 MPa, Young's modulus 2703 → 724 MPa, flexural strength 109.8 → 22.6 MPa, while notched Charpy rises 6.9 → 27.7 kJ/m² and elongation 12.7 → 13.2 %[19][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[18][5]
Mechanical Properties
Tensile strength (XY)MPa82.7 at yield and 84.8 at break on extruded PA66 stock (ASTM D638; converted from 12,000 and 12,300 psi) — no printed figure exists because no unfilled PA66 filament was found[4]26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][3][6]
Young's modulusMPa2413 on extruded PA66 stock (ASTM D638; converted from 350,000 psi)[4]2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][3][6]
Elongation at break%50 at break on extruded PA66 stock (ASTM D638)[4]4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][3][6]
Flexural strengthMPa113.8 on extruded PA66 stock (ASTM D790; converted from 16,500 psi)[4]55 ± 4 printed XY, ISO 178 (Bambu Lab)[5]
Flexural modulusMPa3034 on extruded PA66 stock (ASTM D790; converted from 440,000 psi)[4]2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5]

Other impact dataIzod 53 J/m on extruded PA66 stock, converted from 1.0 ft-lb/in (ASTM D256)[4]Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][3]
Layer adhesion / Z tensileMPaNot documented15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5]
Brittleness1–5Not documentedBrittle — snaps with little warning[5]
Hardness (scale-specific)Shore A / Shore D / RockwellShore D 86 and Rockwell 85 (108) — the source does not name the scales on extruded PA66 stock (ASTM D2240, D785)[4]Not documented
Creep resistance / sustained load1–5Not documentedPoor — no wood-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[20][21][22]
Fatigue / repeated-flex resistance1–5Excellent — living hinges viable[1]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[23][5]
Elasticity / flexibility1–5Semi-flexible[17]Rigid[5]
Z strength as % of XY%Not documented58 by tensile, 51 by flexural (printed, Bambu Lab)[5]
Wear resistance & frictionWear factor 200e-10 in3*min/(ft*lb*h) on extruded PA66 stock (ASTM D3702); Ensinger lists very good slide and wear properties[4]Not documented
Thermal Properties
HDT at 0.45 MPa°C232 on extruded PA66 stock (ASTM D648 at 66 psi; converted from 450 °F)[4]60 (ISO 75, 0.45 MPa)[5]
HDT at 1.8 MPa°C90 on extruded PA66 stock (ASTM D648 at 264 psi; converted from 194 °F) — the gap to the 0.45 MPa figure is the widest in the dataset[4]57 (ISO 75, 1.8 MPa)[5]
Glass transition (Tg)°CNot documented54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[5][6]

Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[24]
Electrical & ESD propertiesVolume resistance 1e15 ohm-cm and dielectric constant 4 on extruded PA66 stock (ASTM D257, D150)[4]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[25]Low hazard — minimal VOC and particle emission[25]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[25]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[25]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[25]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[25]None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[15]
Post-Processing
Sanding & machiningNot documentedSands and stains like timber — the usual reason for choosing it[3]
Support material pairingNot documentedSupport for PLA (Bambu Lab)[5]
Dimensional accuracy & detailNot documentedWood grain hides layer lines; colour darkens with nozzle temperature[5][3]
Solvents & Solubility
Soluble inDissolved at 23 °C by formic acid above ~80 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[26]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[27]
Softened or crazed byZinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[26]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[27][28]
Solvent welding & smoothing agentNone — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[26]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[29][28]
