Identity & Market
Base polymer / chemistryPA6/66 copolymer — a nylon alloy that lowers the melting point and improves printability against straight 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/cm³1.12 (ISO 1183, Polymaker CoPA)[1]1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[5][4][6]
Typical priceUSD/kg1 kg-equivalent spools cluster near 65[7][8][9]1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[10][11][12]
Price range across brandsUSD/kg62–113 across brands; add:north Adura 62, PrimaCreator NylonPower PA6/66 65 at 500 g, Polymaker CoPA 67, 3DXTech AmideX Nylon 6-66 113[7][13][8][9]14–76 across brands; SUNLU 14, ELEGOO 19, Bambu Lab 25, Prusament 44, Filament PM 49 on 0.5 kg spools, colorFabb 76[11][10][14][15][16][12]
Market availability1–5Available from several mainstream brands[7][13]Stocked by most mainstream brands[10][11][15][6]
Spool sizes & diameters1.75 and 2.85 mm; 0.5, 0.75 and 1 kg spools[7][13][8][9]1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[15][6][10]
Typical applicationsGeneral-purpose nylon parts and, unusually, CoPA can support itself if the support is removed before it absorbs moisture[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°C250–270 (Polymaker CoPA)[1]190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][4]
Bed temperature°C25–50 (Polymaker CoPA)[1]35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6]
Enclosure / chamber requirement1–5Enclosure required (passive) — Polymaker specifies a chamber at ambient temperature[1]Open frame is fine[5]
Part cooling fanNot documentedFan on[5]
Maximum volumetric flow (mm³/s; see test conditions)mm³/s16 at Polymaker's 200 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][17]Not documented
Warping tendency1–5Not documentedNone[5]
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning; must be kept below 20 % RH throughout[1][18]Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[19][5]
Extruder requirementNot documentedNozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[19]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely for unfilled grades[20]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[19][21]
Abrasiveness1–5Non-abrasive when unfilled[20]Moderately abrasive — wood fill[19]
Nozzle clog risk1–5Very high — frequent jams without careful setup[22][18]Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[19]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Very high (>2 %) — Polymaker's own wet-state specimens reached 6.16 % moisture content after 48 h immersion at 60 °C[1][18]High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5]
Equilibrium moisture content at ~50 % RH%Not documented1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5]
Drying temperature & time100 °C for 8 h (Polymaker CoPA)[1]55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][19]
Symptoms when wetPopping and cracking during extrusion, then hard-to-diagnose defects[22]Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[19]
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 %[1][22]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]
Storage requirementPolymaker states CoPA must always be stored and used below 20 % relative humidity[1]Not documented
Hydrolysis at melt temperaturePolymaker requires a 100 °C dry for 8 h and storage below 20 % RH; no molecular-weight loss figure is published, and the published wet data is conditioning rather than melt hydrolysis[1][23]Not documented
Mechanical Properties

Elongation at break%12.7 ± 2.1 printed XY dry and 13.2 ± 2.3 wet, ISO 527 (Polymaker CoPA)[1]4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][4][6]

Charpy impact, notchedkJ/m²6.9 ± 1.4 printed XY dry and 27.7 ± 1.2 wet, ISO 179 notched (Polymaker CoPA) — impact quadruples when conditioned[1]3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][4]
Other impact dataNot documentedCharpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][4]
Layer adhesion / Z tensileMPa45.8 ± 1.5 printed Z dry, falling to 13.7 ± 1.2 wet, ISO 527 (Polymaker CoPA)[1]15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5]
Brittleness1–5Tough — absorbs impact, yields before breaking[1]Brittle — 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 unfilled PA66 stock (ASTM D2240, D785)[24]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[25][26][27]
Fatigue / repeated-flex resistance1–5Excellent — living hinges viable[20]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[28][5]
Elasticity / flexibility1–5Semi-flexible[22]Rigid[5]

Thermal expansion (CTE)µm/m·K81.0 on extruded unfilled PA66 stock (ASTM D696; source states 4.5e-5 in/in/°F) — the same chemistry as a PA6/66 copolymer[24]Not documented
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[29]
Water / humidity resistance in service1–5Absorbs water, properties shift — 6.16 % uptake cost 56 % of tensile strength and 73 % of modulus[1]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[30]Low hazard — minimal VOC and particle emission[30]
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[30]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[30]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[30]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[30]None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[19]
Post-Processing
Sanding & machiningNot documentedSands and stains like timber — the usual reason for choosing it[4]
Support material pairingCoPA can support itself, but Polymaker warns the support bonds permanently if it absorbs moisture before removal[1]Support for PLA (Bambu Lab)[5]
Dimensional accuracy & detailNot documentedWood grain hides layer lines; colour darkens with nozzle temperature[5][4]
Solvents & Solubility
Soluble inDissolved at 23 °C by formic acid above ~50 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[31]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[32]
Softened or crazed byZinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[31]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[32][33]
Solvent welding & smoothing agentNone — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[31]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[34][33]
