Identity & Market
Base polymer / chemistryABS compounded with a conductive carbon filler for static-dissipative parts[1]PA6/66 copolymer — a nylon alloy that lowers the melting point and improves printability against straight PA6[2][3]
Densityg/cm³1.09 (ISO 1183)[1]1.12 (ISO 1183, Polymaker CoPA)[2]
Typical priceUSD/kg1 kg-equivalent spools span 47–167; the middle of the market is about 103[4][5][6]1 kg-equivalent spools cluster near 65[7][8][9]
Price range across brandsUSD/kg47–167 across brands; IEMAI 47, YXPOLYER 65, 3DXTech 140 at 750 g pricing; the EMI-shielding ABS grade runs 167[4][5][6]62–113 across brands; add:north Adura 62, PrimaCreator NylonPower PA6/66 65 at 500 g, Polymaker CoPA 67, 3DXTech AmideX Nylon 6-66 113[7][4][8][9]
Market availability1–5Niche, a handful of specialist brands[4]Available from several mainstream brands[7][4]
Spool sizes & diameters1.75 and 2.85 mm; 750 g spools[4]1.75 and 2.85 mm; 0.5, 0.75 and 1 kg spools[7][4][8][9]
Typical applicationsElectronics handling fixtures, trays and jigs used around static-sensitive parts[1]General-purpose nylon parts and, unusually, CoPA can support itself if the support is removed before it absorbs moisture[2]
Printing Parameters
Nozzle temperature°CNot documented250–270 (Polymaker CoPA)[2]
Bed temperature°CNot documented25–50 (Polymaker CoPA)[2]
Enclosure / chamber requirement1–5Enclosure recommended[10]Enclosure required (passive) — Polymaker specifies a chamber at ambient temperature[2]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][11]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented16 at Polymaker's 200 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][12]
Warping tendency1–5High — enclosure needed for reliable large parts[10]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[10]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[13]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[10]Advanced — enclosure, hardware upgrades, tuning; must be kept below 20 % RH throughout[2][14]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely for unfilled grades[15]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Non-abrasive when unfilled[15]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-ABS, only an 80 °C pre-dry[16]Very high — frequent jams without careful setup[17][14]
Heat-creep / jam sensitivity1–5Slightly sensitive[11]Not documented
Hotend requirementNo special hot-end required[11]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[18][19][16]Very high (>2 %) — Polymaker's own wet-state specimens reached 6.16 % moisture content after 48 h immersion at 60 °C[2][14]
Drying temperature & timeNot documented100 °C for 8 h (Polymaker CoPA)[2]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[14]Popping and cracking during extrusion, then hard-to-diagnose defects[17]
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[14]Measured 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 %[2][17]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[14]Polymaker states CoPA must always be stored and used below 20 % relative humidity[2]
Hydrolysis at melt temperatureNot documentedPolymaker 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[2][20]
Mechanical Properties
Tensile strength (XY)MPa58 at break (printed XY, ISO 527) — the conductive filler raises strength above the unfilled grade's 42[1][21]78.0 ± 0.7 printed XY dry and 34.3 ± 2.5 wet, ISO 527 (Polymaker CoPA)[2]
Young's modulusMPa2130 (printed XY, ISO 527)[1]2703 ± 259 printed XY dry and 724 ± 61 wet, ISO 527 (Polymaker CoPA)[2]

Layer adhesion / Z tensileMPaNot documented45.8 ± 1.5 printed Z dry, falling to 13.7 ± 1.2 wet, ISO 527 (Polymaker CoPA)[2]
Brittleness1–5Moderate[1]Tough — absorbs impact, yields before breaking[2]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedShore D 86 and Rockwell 85 (108) — the source does not name the scales on extruded unfilled PA66 stock (ASTM D2240, D785)[22]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1]Not documented
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break 4 %, well below unfilled ABS[1][21]Excellent — living hinges viable[15]
Elasticity / flexibility1–5Rigid[1]Semi-flexible[17]
Z strength as % of XY%Not documented59 dry (45.8 Z against 78.0 XY) and 40 wet, printed[2]
Thermal Properties
HDT at 0.45 MPa°CNot documented111 (ISO 75, 0.45 MPa, Polymaker CoPA)[2]
HDT at 1.8 MPa°CNot documented70 (ISO 75, 1.8 MPa, Polymaker CoPA)[2]

Annealing responseNot documented80 °C for 6 h (Polymaker CoPA)[2]
Thermal expansion (CTE)µm/m·KNot documented81.0 on extruded unfilled PA66 stock (ASTM D696; source states 4.5e-5 in/in/°F) — the same chemistry as a PA6/66 copolymer[22]
Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[23]Not documented
Water / humidity resistance in service1–5Not documentedAbsorbs water, properties shift — 6.16 % uptake cost 56 % of tensile strength and 73 % of modulus[2]
Food contactNot food safe — Polymaker cites potential chemical leaching[13]Not documented
Biodegradability / compostabilityNot biodegradable[13]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[13]Not documented
Electrical & ESD propertiesSurface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ABS[1][21]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[24][10]Moderate — measurable VOCs and UFPs, ventilation advised[24]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[24]Up to 180 caprolactam, the dominant VOC from nylon; total VOC reached nearly 200 µg/min, the highest of the nine filaments tested[24]
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[24]≈2 × 10⁸ median — low for ultrafine particles despite the highest VOC mass of any filament tested[24]
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[24][10]Caprolactam, at up to 180 µg/min from nylon filament — the largest single-VOC emission rate measured in the study[24]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[24][10]Ventilated room or enclosure recommended[24]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[13]Not documented
Painting & finishingPaints readily after light abrasion[13]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[25][10]CoPA can support itself, but Polymaker warns the support bonds permanently if it absorbs moisture before removal[2]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[26][23]Dissolved at 23 °C by formic acid above ~50 %, phenol, m-cresol, 96 % sulphuric acid or hexafluoroisopropanol — laboratory reagents.[27]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[26][28]Zinc chloride solutions stress-crack it — 10 % marginal, 37 % not resistant; alcoholic calcium chloride dissolves it.[27]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[29]None — nylon's only solvents are formic acid, phenol and HFIP, all of which degrade the part they wet.[27]
